Feature Creation Tools Overview

Create features in the target layer Divide

Buffer

Copy Parallel

Union

Intersect

Create features in the same layer Split

Merge

1-20

Copyright © 1999–2001 ESRI. All Rights Reserved. ArcGIS

Divide

Creates features at a given interval along a line Can specify number or distance

Electric line

Target layer

Poles

1-21

Copyright © 1999–2001 ESRI. All Rights Reserved. ArcGIS

Buffer

Buffers selected features by a specified distance

Two discrete polygons in target layer

1-22

Copyright © 1999–2001 ESRI. All Rights Reserved. ArcGIS

Copy Parallel

Copies a line feature parallel to the original feature Positive is on the right side of the feature

Creates feature in target layer

1-23

Union and Intersect

Creates features in the target layer

Does not delete original features

Union Example: Creating a sales territory

Intersect Example: Overlapping area of sales territories

1-24

Labeling features differently

Classes are groups of features labeled the same way (e.g., larger cities displayed with larger text)

Can create multiple classes

SQL expression defines the features in a class

Creating annotation

Convert labels to annotation Current scale is used as the reference scale

Options for storage

Define an annotation feature class in ArcCatalog Feature linked

Annotation is added with new feature

Convert from coverage annotation Tool in Labels category of the Customize dialog

Storing annotation

In a graphics layer

As geodatabase features When the source feature moves, the annotation does not move

As feature-linked geodatabase features When the source feature moves, so does the annotation
