STEP2: SETSYMBOLOGY

In this step, you will learn how to change the symbology of layers in ArcMap.

Click theLaunch ArcMapbutton inArcCatalogto start theArcMapapplication.

InArcMap, confirm thatA new empty mapis chosen and click OK.

Resize theArcCatalogandArcMapwindows so you can clearly see both

applications.

Click the Citiesfeature class from theAdminfeature dataset and drag and drop it

intoArcMap.

MaximizeArcMap.


15/168


Using geodatabase data in ArcMap

Click theAdd Databutton and navigate to the folder connection you created

earlier (C:\Student\CEPA\Database\ShelbyCounty) and open Shelby.mdb.

In theAdminfeature dataset, click County, and clickAddto add the layer to themap.

NOTE: Dragging and dropping from Catalog and using the Add Data buttonare two ways to get layers into ArcMap.

Next, you will experiment with the symbology of both

layers. There are many ways to change the symbology of a

layer. You will try three different methods. Under the layers

name in the Table of Contents there is a patch that represents

what that layer looks like in the map.

Right-click on the patch for County, and experiment with different colors includingtheNo Coloroption.

Close the Symbol Selectordialog.

Left-click on the patch for Cities.

Notice how there are more options for customizing the symbol than if you had right-

clicked. By left-clicking the symbol you have access to the Outline Color and Width,

as well as the Fill Color, and you can choose from many Stylesheets. Right-clicking

gives you access to only the Fill Color.

These methods change the color for all of the features in the layer. In other words, all

the cities are the same color. The third option for changing symbology addresses that

issue.

Click Cancelto close the Symbol Selector.

The Layer Properties context menu contains many useful options for setting

symbology.

Right-click the Citieslayer (the text, not the patch), and click Properties.

NOTE: You can also access this menu by double-clicking on the layer.

Click the Symbologytab.

Notice that the current symbology is set to Single symbol. Most layers are symbolized

this way by default. Next, you will symbolize the cities so that each city is a different

color.

Patch


16/168


Creating and Editing Parcels with ArcGIS Desktop Using geodatabase data in ArcMap

On the left side of the active window, just below Single symbol, click Categories.

This will allow you to symbolize the cities individually, based on unique values from a

field in the attribute table.

For Value Field, chooseNAMEfrom the dropdown list.

Click theAdd All Values button.

Every unique value for the NAME field is added to the list. You can change the color

scheme by selecting a predefined scheme from the dropdown list. You can also change

individual symbols within a scheme by double-clicking a color patch in the

Symbology Preview window.

Your Layer Properties dialog should look like the example below.

Click OKto apply the changes, and close theLayer Propertiesdialog.

NOTE: Apply will also apply the changes, but it will leave the LayerProperties dialog open. When you click OK, ArcMap assumes you arefinished changing properties, so it closes the dialog.


17/168



Using either one of the methods you have already learned for adding a layer to a

map, add theMap_Gridlayer from theIndexfeature dataset.

Question 7: Where did the cities and counties go? _________________________

Layers in the Table of Contents draw from the bottom to the top. The Map_Grid layer

is just covering the other layers in your map. You can drag layers up and down in the

Table of Contents to change the draw order.

Click theMap_Gridlayer, and drag it under the Citieslayer and drop it.

The Cities and Counties should now display on top of the Map_Grid layer.

Click the symbol for theMap_Gridlayer.

For Fill Color, clickNo Color.

For Outline Width, click 1.

For Outline Color, click a red color from the palette and click OK.

Drag theMap_Grid layer back to the top of the Table of Contents.

You should now be able to see the outline of the Map_Grid, the cities with unique

colors, and the county areas.

Select all three layers by holding the Ctrlkey and clicking each layer name.

Right-click one of the selected layers and click

Group.

Notice that all three layers are now included in a

group layer called New Group Layer. Group layers

are a way to group certain layers together so you

can toggle them all off and on together.

Next, you will change the name of your group layer.

Click onNew Group Layer, pause for a second,then click again (this is not a double-click, or a

right-click. The second click makes the text

editable). Change the name of the group layer to BaseLayer

NOTE: You can also change the name of a layer by going to the LayerProperties > General tab.


18/168



Right-click onBase Layer, and click Save As Layer File.

Save this layer file in the C:\Student\CEPA\Exercise02 directory asBaseLayer.

Click Save.

Start a new map by clicking theNew Map Filebutton .

When prompted to save changes to Untitled, chooseNo.

In your new map, click theAdd Databutton.

Navigate to and addBase Layer.lyrto your map. Notice how the symbology you

created earlier is maintained.

NOTE: Layer files are a way to store symbology properties, as well as anyother properties you can change within the Layer Properties dialog. You canadd layer files to maps as you just did, or you can import the symbology froma .lyr file into another layer. The idea is that once you create a certain type ofsymbology, you can always reuse the layer files instead of re-creating thesymbology every time you want it.

STEP3: NAVIGATEAROUNDTHEMAP

In this step, you will learn how to use the Pan and Zoom tools located on the Tools

toolbar in ArcMap. These tools are very useful for exploring your data. You will also

make some attribute selections.

Add the stand-alone Streets_classfeature class from the Shelby.mdbto your map.

NOTE: For the purposes of this class, you are only working with a subset ofthe roads.

Right-click the Streets_classlayer, and clickZoom To Layer.

Notice how the streets are symbolized by unique values

based on the Street_Type field. This is because the streets

have subtypes. Feature classes that contain subtypes are

rendered this way by default.


19/168



Next you will use the zooming tools on the Tools toolbar. Experiment with the

following tools: Zoom In, Zoom Out, Fixed Zoom In, Fixed Zoom Out, Pan, Full

Extent, Go Back To Previous Extent, and Go To Next Extent. The Tools toolbar should

be floating in your map.

Now you will find the intersection of Creek Bend and Winter Harbor roads. There are

many ways to accomplish this goal. You will combine two methods in the following

steps.

From the Selectionmenu, click Select By Attributes.

This operation will select features based on attribute values in the layers table. This

dialog works by creating SQL (Structured Query Language) statements. You can type

or click in your query (SQL statements are syntax sensitive).

In the Select By Attributesdialog, setLayerto Streets_class, andMethodto Create

a new selection.

Double-click the [NAME]field from the Fieldslist to add it to the SQL query.

Single-click the equals sign.

Click the Get Unique Values button to get all of the values for names to show up in

the list.

Scroll down and locate Creek Bendand double-click it.

Zoom Out

20/168



Your Select By Attributes dialog should appear as follows:

If your expression is different that what is shown above, you can click the Clear button

to start over.

Click the Verifybutton to ensure the syntax of your expression is correct.

If your query is successful, clickApply. If it was unsuccessful, Clearit and try

building it again.

All street segments with the name of Creek Bend should be highlighted in a light blue

in the map. The selected streets appear on the left side of the streets layer about half

way down.

NOTE: If you wanted to zoom into the selected streets, you could right-clickthe layer and choose Selection > Zoom to Selected Features, or you could useany of the zooming tools you learned about earlier.


21/168



In the Select By Attributes dialog,change theMethodtoAdd to current selection,

and replace Creek Bendwith Winter Harbor.

ClickApply.

Close the Select By Attributesdialog.

You have selected all of the streets named Creek Bend and Winter Harbor. Next you

will zoom to the selected features.

Right-click on Streets_classin the Table of Contents, and click Selection > Zoom To

Selected Features.

Another way of locating specific features is by using the Find button. The Find button

looks like a pair of binoculars and is located on the Tools toolbar.

Click the Findbutton .

Click or verify that the Featurestab is chosen.

For Find, type Grand Bay

ForIn layers, click the Streets_class.

For Search, clickIn fields, choose the [NAME]field from the list, then click Find.

Click the title bar of the Finddialog and drag it to the lower right corner ofArcMap.


22/168



Right-click Grand Bayin the Finddialog, and choose Flash featurefrom the

context menu.

Grand Bay street should flash on the left side of the map.

Question 8: Does Grand Bay intersect Creek Bend? ________________________

Close the Finddialog.

The Identify tool is also useful for finding and inspecting features. This tool is located

next to the Find button.

Click theIdentifytool and click the street that intersects Grand Bay.

Question 9: What is the name of the intersecting street? _____________________

In theIdentify Resultsdialog, forLayers, click in the dropdown and choose

Map_Grid.

Notice how the only features that get identified are ones in the Map_Grid layer.

Click on Grand BaytoIdentifywhat grid it falls inside of.


23/168



Question 10: What map number does Grand Bay fall within? ________________

The Measure tool is located on the Tools toolbar as well. It allows you to measure

linear distances between features. Measurements appear on the status bar in the lowerleft corner of the ArcMap display. You can clear the results by double-clicking or

hovering your mouse over another tool or button. When you are through using the

Measure tool, it is good practice to click the black pointer on the Tools toolbar as a

default pointer.

Locate the street namedDouble Springsusing one of the methods you learned

earlier. It is in the general vicinity of Grand Bay.

Use theMeasuretool to find out the length ofDouble Springs.

Question 11: Approximately how long is Double Springs? __________________

Question 12: What is the value in the SHAPE_Length field of Double Springs? __

Hint: You can use the Identify tool to find out.

NOTE: The point of the two questions above is to show you that you cannotget the exact length of the line while using the Measure tool.

You have learned how to select, find, and zoom to specific features on the map as well

as how to control the appearance of those features by setting symbology. These skills

will be necessary in order to find where to do your edits in the following lessons and

more importantly, in your work environment.

ExitArcMapwithout saving any changes.

Preparing to edit

EXERCISE3: PREPARINGTOEDIT

In this exercise, you will learn some skills you need to understand before editing in

ArcMap. In order to edit data in ArcMap there are some environment and drawing

variables that you must set first. Some of these options will only be set once, while

some will be changed every time you edit.

STEP1: SETSYMBOLOGYANDCREATEALAYERFILE

First you will symbolize the important layers you will use throughout the class and

save them as a group layer file. This will allow you to create the symbology once and

when you add the group layer to any map you will see all of the layers you need and

they will be symbolized correctly.

StartArcMap, and clickA new empty map.

Click theAdd Databutton, and navigate to the Cadastralfeature dataset in the

Shelby.mdb.

Add Cadastral_Topologyto the map by clicking on it and clickingAdd.

NOTE: Double-clicking it would also add it to the map and close the AddData dialog.

Choose Yeswhen promptedDo you also want to add all the feature classes that

participate in Cadastral_Topology to the map?

This is a method of adding more than one feature class to the display at once. You also

could have added them one at a time or selected certain ones to add.

Also from the Cadastralfeature dataset, add the Parcel_Anno, Parcel_Dim_Anno,

and ConstructionLines layers as well.

Hint: You can hold the Ctrl button in order to select multiple layers to add at once.

! Notice how long it takes for these layers to finish drawing.When these layers finish drawing, you are unable to see what the computer has spentall that energy drawing. This is a prime example of when visible scale range is

important. You will be setting symbology for many layers in the coming steps, so it is

not necessary for your machine to try and redraw the map every time you make a

change.

Tun off the visibility for every layer in your map.


30/168


Creating and Editing Parcels with ArcGIS Desktop The ArcMap editing environment

In order to locate the parcels you want to edit, you will also need the Streets layer.

Add the stand-alone Streets_classfeature class from Shelby.mdbto the map and turn

off its visibility.

You will not need the Plan_Pointslayer for this class, so right-click that layer and

clickRemove.

Many layers in the map have subtypes and therefore take up a lot of space in the Table

of Contents. You will solve that problem in the next couple of tasks.

At the bottom of the Table of Contentsensure theDisplaytab is active.

Click the minus sign beside each layer to hide its symbology and save space in the

Table of Contents. Your TOC should look like the following picture.

Right-click on the Parcel_Lineslayer, and click Properties(or you can double-click

on the layer to open theLayer Propertiesdialog).

Click the Symbologytab and notice that the lines are symbolized using Unique

Valuesfrom the Value FieldcalledLINE_TYPE.

This symbology was applied automatically because the Parcel_Lines feature class is

divided into subtypes. When feature classes with subtypes are added to ArcMap they

are automatically symbolized by subtype. You saw this earlier with the Streets_class

layer. You can change this symbology however you want. Sometimes for editing

purposes, it is nice to see where lines come together and where they are continuous.

You can accomplish this task easily by setting symbology to include points at the ends

of lines.


31/168


Preparing to edit

For Show, click Features.

Now all of the Parcel lines will appear the same regardless of subtype. Now you will

set exactly how you want the lines to look.

Left-click the current symbol for Parcel_Lines (see above)to open the SymbolSelector.

Click Propertiesto take you to the Symbol Property Editor.

For Type, click the dropdown and change it to Cartographic Line Symbol.

Click the Color button and change the color to Cretean Blue (third column from the

right, third blue from the top).

NOTE: You can hover your mouse over the color to display its name.

For Width, confirm or set it to 1.

Click theLine Propertiestab to set symbology for the ends of the lines.

UnderLine Decorations, click the bottom option that places arrows at the beginning

and end of lines.

Click Propertiesso that you can set the properties of the arrows and change them to

circles.

Current Symbol


32/168



In theLine Decoration Editor, click Symbol, and change the symbol to a Circle, Size

to 6, and Colorto Cretean Blue.

Click OKto all of the dialogs to see the changes in the map display.

Now you can tell how many lines are meeting in any particular spot by how many dots

you can see.

Set the symbology for ConstructionLinesjust like ParcelLines, but make the lines

and the line decoration marks red.

Hint: Look back to the previous page to remember the steps for symbolizing as a

cartographic line symbol with line decorations.

Next you will symbolize the Parcels and Streets_class layers.

Right-click the Parcelslayer in the Table of Contents, and choose Properties.

On the Symbologytab, for Show, click Featuresto draw the Parcelslayer with a

Single Symbol.

Click Symbol, and choose theBeigefill symbol.

Click OKtwice.

Change the Streets_classlayer to a Single Symbollegend with a black line symbol,

Size 1.

Next you will set a minimum display scale for Parcel_Lines and the two annotation

layers. This will allow for faster draw time because every single feature will not

always have to be redrawn, depending on scale.

Open the Propertiesof the Parcel_Lineslayer, and click the Generaltab.

For Scale Range, click the option button next toDont show layer when zoomed.

In the Out beyondbox, type 10000, and click OK.


33/168


Preparing to edit

Repeat the process for both annotation layers and set each of their minimum scale

to 3000

Turn on every layer except Parcelsand Zoom to full extent.

Your map should look like the graphic above.

Next you will create a group layer file containing all of the layers in your map. In

subsequent exercises you will be adding this layer file to your maps so you will haveall the necessary layers needed and they will be symbolized the for efficient display.

Like you did in Exercise 2, hold down the Ctrlkey and click each layer in the Table

of Contentsto select it.

Once they are all selected, right-click and click Group.

Rename the new group layerEditing_Layers.

Right-clickEditing_Layers, and click Save As Layer File.

Navigate to the C:\Student\Database\ShelbyCounty directory, and verify that theNameisEditing_Layers.lyr, and click Save.


34/168



At this point, you have two feature layers without scale ranges, one feature layer with

scale range, two annotation layers with scale ranges, a topology layer, and a parcels

layer that is turned off, all packaged together into one group layer called

Editing_Layers. In upcoming exercises you will be adding the group layer to new mapdocuments.

STEP2: SETEDITINGOPTIONS

Now you must prepare your application for editing. You will be turning on toolbars

and arranging them on your desktop. Placement of these toolbars is up to you, but the

suggestions in this manual are a great starting point.

Turn on theEditorToolbarby clicking theEditor Toolbarbutton, as seen on the

graphic below.

NOTE: Your Standard toolbar may be docked in the interface.

Dock theEditorToolbarjust below the Standardtoolbar on the top left of your

screen by clicking its title bar and dragging it.

Most of the tools are inactive because you have not started an edit session yet.

NOTE: A complete list of toolbars can be found by right-clicking in blankgray space anywhere within the ArcMap interface or by clicking View >Toolbars from the ArcMap interface. The Editor Toolbar can be turned on andoff from here as well.

On theEditorToolbar, click theEditor >More Editing Tools.

NOTE: This is an easy way to find toolbars directly related to editing.


35/168


Preparing to edit

Activate both the TopologyandAdvanced Editingtoolbars and dock them beneath

theEditorToolbar.

Most of the tools you need while editing can be found on these three toolbars. Take a

moment to look at the tools. You can inspect them further by choosing the Whats

This? tool , then clicking on any button or tool for more information on that

particular command. You can also use Shift + F1 to get context sensitive help.

Question 1: What license is needed in order to use the Planarize Lines tool on

the Topology toolbar? (Use the What's This? tool) _________________________

Hint: To save time look towards the bottom of the pop-up window.

Now you are ready to start editing in ArcMap. Before you do any edits you must beginan edit session.

ChooseEditor > Start Editing.


36/168



Now that ArcMap is in edit mode, you can expose the snapping environment.

Snapping is a very important aspect of editing. When you set snapping, you are

ensuring that the new features you create are snapping to existing features where

expected. This is important if you are dealing with a topology. A topology containsrules your features must abide by when edited, and snapping will help you obey those

rules.

ChooseEditor > Snapping.

Arrange the Snappingmenu so that it fits below the Table of Contents by clicking

and dragging it by the double horizontal lines.

! As mentioned before, when you are editing, snapping is crucial!

Next you will go to the Options menu of the Editor Toolbar to explore some of the

functionality it offers, as well as change some properties.

ClickEditor > Options.

You may have to pullor adjust from these points


37/168


Preparing to edit

The Editing Options dialog has many useful options including snapping tolerance and

the list of potential editing tasks. Take a moment to explore the contents of each tab.

Click each tab in theEditing Optionsdialog to see what properties can be set.

Next you will change the units.

Click the Unitstab.

SetDirection Typeto Quadrant Bearing.

SetDirection Units toDegrees Minutes Seconds.

SetDisplay angles usingto 0decimal places.

NOTE: This is the format in which you will receive survey data in this class.

Question 2: What is the snapping tolerance set to? _________________________

Hint: Switch tabs.

Click OK.

STEP3: PERFORMAROUGHSKETCHOFAPARCELSPLIT

The parcel split that you will perform in Exercise 4 is located just east of the

intersection of Winchester and County Gate roads.

Using the methods you have already learned, find and zoom to this intersection.

The best method may be to use Select By Attributes.


38/168



After you zoom into the area of interest, clear the selected features.

Hint: There are several ways to clear selections. The Selection dropdown, the

Selection tab, and clicking in white space with the Select Features tool are threeways.

Turn on the Parcelslayer.

Right click on the Streets_class and turn onLabel Features.

Pull out the hardcopy of Plat 1 to inspect it. This plat contains the legal outline of a

new parcel split that you will enter into the database in Exercise 5. Look at the

southwest corner. This new parcel is defined by a closed traverse of five segments,

beginning in the southwest corner at a point 295.43 feet from the centerline of County

Gate Road. You can clearly see the intersection of County Gate Road and WinchesterRoad on the map, but on the plat you can see that the center of County Gate Road is

295.43 feet from the western edge of the new parcel. Below is the area of interest.

Next, you will do a quick drawing using the Measure tool and the measures on plat 1

to see how the new parcel will fit into the existing parcel framework. In Exercise 4,

you will use other tools to create the new parcel, but for now you are just eyeballing

the new parcel.

Your new parcelwill go here


39/168


Preparing to edit

Click theMeasuretool and click the centerline of County Gate Road as shown

below.

Drag theMeasuretool, as shown below, until the status bar (lower left corner of

ArcMap) shows approximately 295 feet, and then click one time.

This will allow you to make other measurements from that point which is roughly 295

feet from the centerline of County Gate Road, just like on the plat. You already have

the first measure. Now use the plat and the measurements on it for the new parcel to

sketch out where the new parcel will be placed.

Move your cursor up roughly 158 feet from the first point, as shown below, and

click.

Begin measurementhere

2nd Click


40/168



As seen on the plat, the northern boundary of the parcel is 102 feet from the point

you just added. Make that measurement and click to add a point as seen below.

Add the next segment, which is 170 feet from the last point heading south. See

graphic below.

The final segment is a little trickier. The plat reads 18.2 feet for the final line. It isclearly longer than 18.2 feet. See the horizontal bar on the lower left corner of the plat.

This gives you some measures and angles. Notice the Arc Length is 84.53 feet. Your

next measure will use the sum of 18.2 and 84.53 (102.73).

From your last point, measure roughly 103 feet and it should end near the other

parcel edge. See graphic below.

Click roughly 102

feet from last point

Click roughly 170

feet from last point

The last click


41/168


Preparing to edit

Now you have a rough sketch using the Measure tool as to how this new parcel will fit

into the existing ones. With the editing tools you will be adding a new parcel. With the

Measure tool you are just seeing where it will lie. Notice that you cannot get the exact

measure with the Measure tool, as seen earlier. The edit tools will allow you to enterthe exact distances from the plat.

Double-click to clear the measure lines.

STEP4: VALIDATETHETOPOLOGYINYOURAREAOFINTEREST

Some of the layers you will be editing participate in a topology. Next you will explore

the rules in the topology and validate it to see if there are any errors in the current

extent.

Right-click the Cadastral_Topologyin the Table of Contents, and click Properties.

Click theRulestab.

Question 3: What rules are present in this topology? _______________________

Hint: You dont need to write down every rule, just familiarize yourself with the

topology rules present in this topology.

Use the scroll bar to scroll right and left to see which feature classes take part in any

given specific rule.

NOTE: Notice that rules may be set across feature classes, as well as withinthe same feature class.

Click OKto close theLayer Propertiesdialog.

On the Topologytoolbar, click the Validate Topology in Current Extentbutton.

You should not see any topology errors. However, you may see topology errors

depending on how tight you zoomed into the street intersection of interest.

! You want to be certain not to Validate Entire Topology as this could takea long time.NOTE: The Validate Entire Topology button is to the right of the ValidateTopology In Current Extent button.


42/168



Validating checks to ensure that no parcels are overlapping, that parcel lines are

coincident with parcel boundaries, that no parcel lines contain dangles, and so on. In

other words, you want to make sure your area is topologically valid before you begin

editing. This way when you validate the topology after performing your edits you canbe sure that any topology errors you find will be errors that you have just made.

STEP5: SETSELECTABLELAYERS

The Selection tab is an important part of the Table of Contents. With it you can toggle

on and off the selectability of a layer, as well as see how many features in each layer

are selected.

Click the Selectiontab.

A check mark next to the layer name means it is selectable.

Question 4: Which layers are currently selectable? _________________________

Click theDisplaytab and uncheck the two annotation layers so they are no longer

visible. Then click on the Selectiontab again.

Click the Select Featurestool .


43/168


Preparing to edit

Draw a box around the intersection of Winchester and County Gate roads including

the corner parcels. You may want to zoom in a little. See graphic below.

Once you release the mouse button you should see selected features in the map and if

you look at the Table of Contents, the Selection tab reports to you how many features

were selected in each layer.

Question 5: How many features were selected? ___________________________

NOTE: The number of features you have selected may vary slightly from theanswer at the end of this lesson.

Click the check boxes next to Streets_classand Parcel_linesto make them

unselectable.

Clear your current selection by clicking where there are no features or by choosing

Selection > Clear Selected Features.

Draw the box again to select features.


44/168



Question 6: How many features were selected this time? ____________________

NOTE: Again, the number may vary, but it should be less than before.

Go to Selection > Clear Selected Featuresto clear the selection.

Make the Streets_classand Parcel_Lineslayers selectable again.

Editing in ArcMap requires constant changing of selectable layers, visible layers,

snapping environment, and the active tool. Being familiar with how, where, and why

to change these settings is crucial.

You will be adding features to the Parcel_Lines layer in upcoming exercises by

snapping new lines to known points on existing lines and then creating Parcels from

the framework defined in plats and deeds. Your layers are now ready to edit.

ExitArcMap without saving.

The parcel editing process

EXERCISE4: THEPARCELEDITINGPROCESS

This exercise is designed to have you go through the process of doing a parcel split

without worrying much about perfecting the individual steps. The point is more for

you to envision the entire process in general. You will detail each part of the process as

this course progresses over the next few days.

STEP1: LOCATETHEAREAOFINTEREST

The first step in editing data is to add the layers to ArcMap and zoom into the area of

interest.

StartArcMap.

Choose Start using ArcMapwithA new empty map.

Add theEditing_Layers layer file to your map.

Use the Findbutton to locate the parcel whose Parcel ID is d0255 00576. Make

sure you put three spaces between D0255 and 00576. Make your Finddialog look

like the one below.

Click Find.


50/168


Creating and Editing Parcels with ArcGIS Desktop The parcel editing process

Right-click on the search result, and clickZoom To Feature.

Close the Finddialog.

This parcels area is about 255 acres. You are going to create a new, landlocked parcelinside the bigger parcel.

STEP2: CREATELINESANDUPDATEATTRIBUTES

ClickEditor > Start Editing.

On theEditor Toolbar, set the Taskto Create 2-Point Line Features, and the Target

to Parcel_Lines: Parcel Line.

Click theRectangletool on theAdvanced Editingtoolbar.


51/168



Click to begin a rectangle in the parcel as shown below. Move your mouse to size

the new rectangle and click again to finish it.

NOTE: The exact size of your new parcel is not important as long as it fits

completely inside the old parcel. However, a smaller parcel will make thingsa bit easier when you create annotation.

You just entered four new parcel lines, but the lines do not have attributes.

Click theAttributes button on the right side of theEditor Toolbar.


52/168



You should notice that these lines have a few attributes, but the majority of the fields

are blank.

NOTE: Your OBJECTID values may differ.

OBJECTID values are generated automatically for every feature; these are system IDs.

LINE_TYPE is the field that defines the subtypes and was automatically populated by

setting the Target to Parcel Line. SHAPE_Length is automatically generated and

updated by the geodatabase.

Tax maps are normally annotated with the legal length and/or direction of the lines that

make up each parcel. Those lengths and directions are missing in the current map.

Next, you will add those attributes by using a button on the Advanced Editing toolbar.

On theAdvanced Editingtoolbar, click theInverse button.

Notice that all four of your new lines now have the COGO attributes of Angle and

Distance.

Click on each feature in theAttributesdialog to see the attributes for each.

NOTE: The features are the four entries under the Parcel_Lines layer. If youclick one of the features in the Attributes dialog, you can see thecorresponding feature on the map highlight momentarily.

You have now created the attributes necessary to annotate the parcel lines. In most

workflow scenarios the COGO attributes are populated by creating the lines from legal

descriptions. In future exercises you will spend a lot of time learning how to

accomplish that task.


53/168



STEP3: CREATINGPOLYGONS

You have created lines in the Parcel_Lines feature class but no polygons in the Parcels

feature class. Try turning on and off those two layers so that you can see exactly whatyou have and don't have.

Click the check boxes next to the Parcel_Linesand Parcelslayers to toggle them

on and off in order to see what is in each.

Confirm your four new lines are selected.

Change the Target to Parcels: Parcel.

On the Topologytoolbar, click the Construct Featuresbutton.

In the Construct Featuresdialog accept the default Cluster Toleranceand ensure

that the check box for Consider existing features of the target layer in the current

extent is checked.

NOTE: Cluster tolerance is the minimum distance between features beforethey are made coincident. If the Consider existing features of the target layer

in the current extent check box in the Construct Features dialog is checked,existing features will be modified by the selected features. For example, ifyou select a line that crosses a polygon more than once, it will split thepolygon in two.

Click OK.

Uncheck the Parcel_Lineslayer in the Table of Contents to see the new polygon

you just created from the selected lines.

You should notice that you have created a new polygon that has the same attributes as

the parcel that it was split from.

Click the Selectiontab.

Make sure the Parcelslayer is checked and all the other layers are not.

Select the new parcel and the surrounding one, and open the Attributesdialog.

Inspect the attributes for each to confirm that they are the same.


54/168



Close theAttributesdialog when finished.

In a production environment this would be a good time to update the parcel attributes,

but to save time, you will skip this part.

STEP4: CREATINGANNOTATION

In this step, you will be working with and creating geodatabase annotation.

Zoom in close to your new parcel.

Click Selection > Clear Selected Features.

You will not need to type in the values of deeded length to create annotation for the

lines you created because those numbers already exist in the attribute table.

Turn off the Parcellayer and turn on the Parcel_Lineslayer if necessary.

Double-click on the Parcel_Lines layer to open theLayer Propertiesdialog, then

click theLabelstab.

ForLabel Field,chooseDISTANCE, then click OK.

On theEditor Toolbar, set the Taskto Create New Feature, and the Targetto

Parcel_Dim_Anno: Standard.

Click View > Toolbars > Annotationto turn on this toolbar and place it on theinterface wherever you like.

Set the dropdown lists on theAnnotationtoolbar as follows.

Now you are ready to add annotation to your new parcel lines.

NOTE: You may need to zoom into the parcel lines to see the annotation.Zoom to each line as you set the annotation so you can see it clearly. With theSketch Tool active, if you press the C, X, or Z keys you can pan, zoom out,and zoom in respectively.

Construction: Follow Feature

Text: Leave this blank

Symbol: Standard


55/168



Expose your snapping environment and turn onEdgesnapping for the

Parcel_Lineslayer.

Click the Sketch Tool, snap to the northern boundary line of your new parcel, thenpress theWkey on your keyboard. Watch for the feature to flash. Watch closely; it

flashes quickly.

Pressing W not only flashes the feature you are going to annotate, but also gets the

attribute ofDistancefrom the feature closest to your pointer and places that value into

the Text dropdown on the Annotation toolbar. The next click you make will direct the

annotation on which feature it should follow. Therefore if you do not click close

enough to an existing feature nothing will happen.

Click once while snapped to the same line to start the Follow Featureprocess.

Notice that a red dot appears on the line (move your mouse around). This is an

indication to you that this is the line that will be annotated. Now you can move your

mouse around the screen and the annotation will follow while remaining on the line.

Press Pto set the orientation of the annotation.

The two graphics from the left illustrate how you can follow the feature and place the

annotation anywhere along it and on either side. The next two graphics illustrate that

by pressing the P key on the keyboard you can place the annotation parallel or

perpendicular to the line. For this exercise you will place it parallel.

Snap TipYour distance willbe different.

PRESSP PRESSP


56/168



The final click you make will determine on what side of the line the annotation is

placed and where it is placed along the line.

Click where you want the annotation to be placed (above or below the line).

The annotation should be placed on the correct side of the line. The process has three

main steps.

1. PressWwith the Sketch Toolwhile snapped to a line to specify the lineto pull attributes from.

2. Click the line you want to annotate (usually the same line).

3. Click where you want the annotation placed along the line.

Repeat the process for the other three lines to annotate them.

STEP5: SAVEYOUREDITSANDYOURMAP

From theEditor Toolbar, clickEditor > Stop Editing, then click Yesto save your

edits.

Click File > Save As.

For File Name, type Ex4, then save it to yourExercise04directory.

Click Save.

ExitArcMap.

SUMMARY

What did you just do?

Set the Task to Create 2-Point Line Features. This ensures that all thelines you draw are individual straight lines or curves and ensures thelines ability to have individual attributes.

You drew lines into the Target layer Parcel_Lines.

You ensured those lines had attributes.

You created parcels in the Target layer Parcels by using the ConstructFeaturesbutton with the new lines you previously drew.

You created annotation for the parcel lines.


57/168



Why does this seem easy? Arguably, the most time consuming part of your normal day

to day workflow will be entering bearing and distance pairs or converting and

adjusting your CAD linework. You skipped that part by simply entering a rectangle.

Further, the parcel you created was landlocked so you didn't have to worry about howit fit compared to the existing parcels. The annotation in this scenario was also simple

and easy to place. Subsequent exercises will deal with these issues further.

Entering a closed traverse from a plat

EXERCISE5A: ENTERINGACLOSEDTRAVERSEFROMAPLAT

In this exercise, you will be using Plat 1 as you data source for entering a new

subdivision. Take out and inspect the plat named Plat1-- County Gate P.D. Second

Amended Phase 10 Parcel 1. You will use the Sketch and Traverse tools in ArcMap to

enter information from the plat.

NOTE: For a complete description of the Traverse tool, see the ArcGISDesktop Help topic Creating edit sketch geometry with the Traverse tool.

STEP1: STARTARCMAPANDPREPAREFOREDITING

NOTE: A digital version of this plat is also included as a PDF file and can befound in C:\Student\CEPA\Database\Miscellaneous\PlatsDeeds\Deed1 &Plat1.pdf

From inspecting Plat 1, you know that the starting point of the traverse is on the north

side of the Winchester Road right-of-way 295.43 feet from the centerline of County

Gate Road.

StartArcMap, and addEditing_Layers.lyr to your empty map.

Find and zoom to the intersection ofWinchester and County Gate Roads.

Hint: Winchester Road is one of two major East/West streets in your study area so

find County Gate road first and simply look for where it intersects a major road.

Label the roads if you need to.

From theEditor Toolbar, clickEditor > Start Editing.

STEP2: FINDTHESTARTINGPOINT

You are now ready to enter the first line. This line will be a guide to help you start the

traverse in the correct position. The line will snap to a point on the centerline of

County Gate Road on one end and also snap to a point on the existing parcel line

295.43 feet from where it starts.

On theEditor Toolbar, click the Sketch Tool .

With the Sketch Tool, snap to and click a vertex on the north side of the Winchester

Road right-of-way (ROW) anywhere along the southern boundary of the parcel just

east of County Gate road.

Move the Sketch Tool along the ROW, and right-click and select Parallelfrom the

context menu. The sketch is constrained to be parallel to the ROW feature.

Choosing Parallel from the Sketch context menu constrains your next vertex so that it

must be parallel to the line you right-clicked on.

Move the Sketch Tooland snap the sketch to the centerline of County Gate Road.

Finally, move the Sketch Toolback exactly on top of the initial vertex, then right-

click and selectDelete Vertexfrom the context menu.

You now have the starting point vertex of the legal description as noted in Plat1.

STEP3: FINDTHETRUEPOINTOFBEGINNING(POB)

Move your Sketch Toolto the east away from the starting point vertex, then right-

click and selectLengthfrom the context menu.

Enter a value of 295.43 and press Enterto set the length constraint for the next

point.

You want the next point to be snapped to the edge of the northern boundary of the

Winchester Road ROW. Snapping is enabled for the Parcel_Lines feature class.

Move the Sketch Tool, snap to the parcel line along the ROW, then click to set the

vertex.

On the keyboard, press F2to finish the sketch.

You just entered a reference parcel line that will not be a permanent part of yourdatabase. The line was entered to create a suitable starting point for the traverse that

you are about to enter.


65/168



STEP4: ENTERTHETRAVERSE

Modify the editing settings as seen below:

On theAdvanced Editing toolbar, click Traverse .

Arrange the Traverse dialog in a place where you can see it and the map at the same

time. You may need to zoom or pan the map to accomplish this.

In the Traversedialog, check the box for Closed Loop, then click the button just to

the left of that box. This is the Interactive Start Point Selection tool.

The Traverse dialog should read Click on the map to set the start point. The

Interactive Start Point Selection tool allows you to click in the map to enter a start

point for your traverse. You will do that in the following steps.

Move the cursor into the map window (you should see crosshairs) and snap to the

eastern end of the reference line you created above. This is the starting point or true

Point of Beginning (POB) of the traverse.

Snapping Parcel_Lines End only

Reference line

Point of Beginning

to snap to


66/168



Snap to the end of the line and click to add a vertex.

From this point you will traverse the boundary of the property by entering bearing and

distance information from one corner to the next. You will proceed in a clockwisefashion.

In the Traversedialog, verify that the dropdown in the upper left corner reads

Direction-Distance.

ForDirection, type 01-00-08-1, and forDistance, type 157.79

Click theAddbutton to add the segment to the traverse.

The values were added to the lower part of the Traverse dialog as segment # 1 with a

complete description of the line. A sketch segment was also added to the map.


67/168



In the Traversedialog, add two additional line segments with the following values:

Direction88-59-52-2andDistance102

Direction01-00-08-3andDistance170

NOTE: Watch the map as you add the traverses.

NOTE: Remember to click the Add button between each entry to add thesegment to the Traverse dialog and to the map sketch. Notice that the first andthird segment directions are identical, but are just in opposite directions.

The next line segment is a curve with parameters as detailed in the curve table on the

plat as follows:

From the upper left dropdown list in the Traversedialog, click Curve.

Enter the curve details as follows: Chord:84.53,Radius:2797.79, Chord

Direction:82-19-32-4, Turn: Right.

The graphic below illustrates how the Traverse dialog will look after entering the

information.

NOTE: The curve turn direction must be determined by visual examinationof the Plat. There are multiple ways to enter curve information. You may haveto change your individual dropdowns in order to enter this information.

ClickAddto add the curve to the traverse.

Click Curve in the dropdown list and change it back toDirection-Distance.

Enter the last line segment with the following values: 81-27-36-4and 18.2

ClickAddto add the final segment to the traverse.

STEP5: EVALUATECLOSUREERRORANDADJUSTTHETRAVERSE

Click the Closurebutton and inspect the information about the traverse.


68/168



Your closure reported as Misclosure As X/Y should be very small (less than a

hundredth of a foot for X/Y), and your Relative Error Ratio should be very close to

1:500,000.

Before completing the traverse you will save it to a text file in case you need to re-

enter it in the future. Once saved as a text file, you can load the text file into the

Traverse dialog.

Right-click anywhere in the Traversewindow, and click Save Traverse.

Navigate to the C:\Student\CEPAfolder and save the file in your Exercise05

directory as Traverse_Plat1.txt.

Since you want the start and endpoint to be snapped together, you will adjust the

closed traverse to set two points at identical coordinates.

Click theAdjustbutton.

ForAdjustment Method selectTransit andclickAccept.

NOTE: For additional help on the Transit adjustment method, go to ArcGISDesktop Help > Contents > GIS Glossary > and search for Transit Rule.

The Traverse dialog and the map sketch are finished and the new line features are

selected in the map window.

Close the Traversewindow.

STEP6: REVIEWTHECOGO ATTRIBUTES

Select your five new lines without having anything else selected.

Hint: Holding down the Shift key can help you make selections like this. Holding

down the Shift key while selecting features will allow you to click on features to

either add or remove them from the selection, while not affecting the other selected

features.

Click theAttributesbutton on theEditor Toolbar.


69/168



Notice how your new lines have COGO attributes. Lines created with the Traverse

tool automatically have the COGO attribute fields populated. For the curve, note that a

complete list of COGO values were calculated for all fields. The attributes for the

curve are the ones being displayed in the graphic.

Close theAttributesdialog.

STEP7: ROTATEANDFITTHENEWPARCELLINESTOTHEEXISTINGFRAMEWORK

Notice that the new lines are not aligned with the existing parcels lines and ROW. You

will rotate the new lines to fit into the existing framework without moving the start

point. In order to do this, you will move the selection rotation anchor to the start point

and then rotate the features.

Click theEdit Tool. Ensure that your new lines are all selected.

Hover your cursor over the selection anchor (i.e., theXin the center of selected

features), then hold down the Ctrlkey and click and drag the anchor to the start

point.

The anchor should snap to the right place because your snapping is set to Parcel_Lines

- End.

Move and snap the anchor here


70/168



Next, you need to rotate the lines around the anchor at the start point, and snap the

features to the existing parcel lines. To do this, you need another anchor for rotating.

From the right side of theEditor Toolbar, click theRotatetooland press and hold Shift + Son the keyboard. This action

creates another anchor as shown below.

Move theRotatetool over the new anchor and click, drag, and

snap this anchor to the southeast corner of the selected features.

The snapping environment must be modified prior to the rotation.

Modify your Snapping Environmentas follows:

With theRotatetool click, drag, and rotate the selected

features until they snap to the existing parcel lines.

The steps above show you how you can rotate features

based on selection anchors and snap them to existing

features.

STEP8: USETHEZIPPERTASK

The Zipper Task is a Developer Sample that adds an editing task to the list. A common

scenario for using this tool is when you have one feature that you want to align the

features from other feature classes to. The Trace tool (or the Replace Sketch context

menu choice) is used to create a sketch of the geometry in the feature, and the ZipperTask will then use this geometry to align the other features. The Zipper Task basically

zipsup the features and makes them coincident.

With theZoom In tool, zoom in really close to any spot near the center of the

southern boundary of the outline as shown below:

If you zoom in close enough you will see that there is a slight difference in the original

ROW and the new line just created. The Zipper Task will zip these together for you.

Use theMeasuretool to evaluate the gap between the two lines. The gap should be

well less than a foot.

Click theEdit Tooland right-click in the map, and clickZoom to Selected Features

to return to the extent of your new parcel lines.

Right-click in the map window, and click Clear Selected Featuresfrom the context

menu.

With theEdit Tool, draw a box around the southern boundary of the parcel, then

right-click and clickAttributesfrom the context menu.

You should have four lines selected: the two original parcel lines and the two new ones

you just drew.

On the left side of theAttributesdialog, click the feature to flash each line so that

you can see which ones are selected.

Next, you will adjust the new lines to fit the existing framework using the Zipper Task

and the selected original lines to adjust the new parcel lines. Using the Edit Tool,you

will select the original polylines and then use the Trace tool to create a sketch of the

geometry selected feature. When the sketch is finished, a dialog appears asking for a

tolerance and the layers to be adjusted. Features from the specified layers that fall

within the tolerance are then aligned to the geometry of the original selected features.

NOTE: The Zipper Task is a Developers Sample which has already beenadded to your workstation. Complete information on this tool can be found athttp://arcgisdeveloperonline.esri.com by searching for Zipper Task.

Locate the two new lines by flashing them in theAttributesdialog.

Right-click in the left side of theAttributesdialog on the new lines and choose

Unselect.

When you have only the two original lines selected, close theAttributesdialog.

Modify the editing settings as follows.

NOTE: If the Zipper Task is not available from the list of tasks, see yourInstructor for assistance.

Click the dropdown arrow next to the Sketch Tool, and choose the Tracetool .

Using the Trace tool, trace the two selected lines by clicking once at the beginning

and double-clicking at the end. You should see a black line being drawn on top of

the selected lines. That is the tracing line.

Edit Task Zipper Task

Sketch Tool Trace tool


73/168



The Trace tool will only trace selected features. You do not need to be overly precise

with your tracing, but you should try and trace the overlapping segments as closely as

possible. After double-clicking and finishing the sketch, the Zipper Parametersdialog

will open.

On theZipper Parametersdialog,

click theAll Topobutton for the

topology layers to be zipped, and

enter a search distance of 1foot.

Click OKto close theZipper

Parametersdialog.

With theZoom In tool, zoom in

really close to any spot near thecenter of the southern boundary of

the outline and confirm that the

overlapping lines are coincident.

Using theZoom Out tool, zoom out until you can see the reference line you initially

created from the initial start point (the 295.43 segment from the road intersection to

the true POB).

Using theEdit Tool, click and delete the reference line.

This line was just used to create a start point and therefore is not truly a parcel line.

On the Topologytoolbar, click the Validate Topology In Current Extent button .

There should be no new errors.

STEP9: CONSTRUCTTHENEWPARCELPOLYGON

You have now successfully created and cleaned the outline of a new parcel. Next, you

will construct the associated parcel using the new lines and the Topology toolbar.

Using theEdit Toolselect the five new parcel lines.

In the Table of Contents, turn on the Parcellayer visibility, then turn off and on the

Parcel_Lineslayer, and notice that there is not a new parcel where the lines have

been constructed.

Modify the editing settings as follows:

On the Topology toolbar, click Construct Features .

Accept the default value for the Cluster

Tolerance, and ensure the box next to

Consider existing features of the target layer

in the current extentis checked.

Click OKon the Construct Featuresdialog.

Click the Validate Topology In Current Extentbutton.

You should see no errors.

Go toEditor > Stop Editing, and click Yesto save your edits.

Continue to Exercise 5B.

NOTE: In a production environment, you would have had to additionallycreate attributes for the new parcel, update the attributes for the parcel thatwas split, and create annotation. This exercise was intended to simplyacquaint you with using the Traverse dialog, using snapping and rotation

anchors, and the Zipper Task. Hopefully, those three aspects of parcel editingmake sense to you now.

EXERCISE5B: ENTERINGACLOSEDTRAVERSEFROMADEED

STEP1: STARTARCMAPANDPREPAREFOREDITING

In this exercise, you will use a deed as a guide for entering a new subdivision. Take out

and inspect the deed named Deed1 for Buckingham Farms P.D. Parcel I

NOTE: A digital version of this plat is also included as a PDF file and can befound in C:\Student\CEPA\Database\Miscellaneous\deed1.pdf.

StartArcMapand addEditing_Layers.lyrto your map.

Find and zoom into the intersection referenced in the deed.

On theEditor Toolbar, clickEditor > Start Editing.

Set the editing settings as follows:

STEP2: FINDTHESTARTINGPOINT

The first task is to find the Point of Beginning (POB). This time you will create the

lines that lead to the POB in a layer called ConstructionLines. The deed mentions that

the Shelby Dr. ROW is 108 feet.

Use theMeasuretool to see if this looks about right to you.

To the west, the ROW of Shelby drive is approximately 108 feet wide, but east ofMeadow Cliff Road the ROW is variable and significantly less.

As stated in the deed, the starting point is located at the intersection of the north line of

East Shelby Drive with the center of Meadow Cliff Drive. The Intersection tool on the

Editor Toolbar is a great method of finding a starting point based on the implied

intersections of two other features.

Question 1: What are the details of the first three courses from the starting point to

the true POB? ______________________________________________________

Hint: Answers are 01-21-48-3 and 77.37; 89-3-45-2 and 1222.49; and 01-21-40-1

and 103.91.

Click the arrow next to the Sketch Tool and click theIntersection Tool .

When you place the Intersection Tool over existing line features you will see a line

added to the map. This line is not a feature. It is a temporary line that is used to create

the starting point (vertex) for a feature (e.g., ConstructionLines). You need to click on

two segments to locate the virtual intersection and add the point.

With theIntersectiontool, click on Meadow Cliff Road as shown below.:

A dark line should be added to the map representing the first line. For this tool to

work, you need an implied intersection between two lines.

First intersection line


77/168



Click the parcel boundary as shown below to add the second temporary line for the

intersection.

Notice that the two lines cross at the implied intersection of the two features you

chose. The second click that you just performed should have placed a vertex at the

intersection of the two lines that you clicked on.

Now you have a starting point to work from in order to locate the true POB. In the next

step, you will create a ConstructionLine that will locate the POB.

STEP3: FINDTHETRUEPOB

You will use the Sketch Tool context menu to create the Construction lines that lead to

the true POB.

Click the Sketch Tool and move your pointer into the map area.

Right-click and selectDirection/Lengthfrom the context menu.

Enter the first three direction/distance segments described in the deed with the

skills learned in the first step of this exercise, and click Finish Sketch.

Second intersection line


78/168



NOTE: Remember that while the Sketch Tool is active you can use the Z, X,and C keys to zoom in, zoom out, and pan respectively.

The lines you just drew represent a sketch to the true POB. You created three lines in

order to find this point. You can delete the first two lines if you want, as you will notneed them anymore.

Click theEdit Tool.

Click anywhere off a feature to clear the selection.

Click the first small line on the left to select it.

Hold down the Shiftkey and click the long horizontal line to add it to the selection.

Press the Deletekey.

The north end of the one remaining line represents the true POB.

STEP4: ENTERTHETRAVERSE

You will snap the POB of the traverse at the end of the line you just created in the

ConstructionLines layer. Also, you will enter the complete traverse into the

ConstructionLines layer rather than the Parcel_Lineslayer as used in Exercise 5A.

Modify the editing settings as shown below:

On theAdvanced Editing toolbar, click the Traverse tool and check the box for

Closed Loop.

Click the button next to Closed Loopfor defining a start point.

Move your cursor into the map, snap to the end of the line (the true POB), and click

to add a vertex.

Using the Traverse dialog, enter the traverse values as determined from Deed1.

There are eight direction/distance pairs and one curve. While entering the curve use

Radius, Chord Length, Chord Direction, and Turn.
