BufferBuffer is one of the Analysis tools used in calculating proximity. This tool creates a new feature class of buffer polygons around either polygon, line, or point features.

Buffer

ClipClip is one of the Analysis tools used for extracting features or parts of features from a feature class. This tool uses a polygon boundary to cut features and their attributes from a feature class.

Clip

Dissolve is one of the Data Management tools used for generalizing features. This tool combines like features based on a specified attribute or attributes.

Dissolve

IntersectIntersect is one of the Analysis tools used to perform overlay analysis on feature classes. This tool builds a new feature class from the intersecting features common in both feature classes.

Intersect

UnionUnion is another Analysis tool used to perform overlay analysis on feature classes. This tool builds a new feature class by combining the features and attributes of each feature class.

Union

Add XY CoordinatesAdd XY Coordinates is one of the Data Management tools for managing features and their attributes. This tool adds the POINT_X and POINT_Y fields to the feature's attribute table and calculates the x,y location for the fields for labels, points, tics, or nodes.

Add XY Coordinates

EraseErase is one of the Analysis tools used to perform overlay analysis on feature classes. This tool creates a feature class from those features or portions of features outside the erase feature class.

Erase

Feature to Line, Feature to Point, and Feature to PolygonFeature to Line, Feature to Point, and Feature to Polygon are Data Management tools used for manipulating features. These tools create line, point, or polygon features from other features.

Feature to Line, Feature to Point, and Feature to Polygon

SplitSplitSplit is one of the Analysis tools used for extracting features or parts of features from a feature class. This tool breaks the features into multiple features.

What Is A Model ?Models are how you automate your work

Software application: ModelBuilder

Drawing the Process

Why Modeling…? document the processing steps (workflow) that you carried out

You will forget You may need to do it again

re-run the analysis to experiment with different parameters to see how results are affected

rerun the analysis if you find a mistake carry out repetitive, multi-step tasks provide other users (e.g. operations staff) with an exact

workflow that they can replicate
