Geoprocessing Methods
Common Geoprocessing tasks include:• Converting data (converting a shapefile to a
geodatabase feature class or converting geometry types)
• Overlaying data (uniting or intersecting datasets)
• Extracting data (clipping a subset of data, or selecting data with certain characteristics)
• Managing data (joining fields, copying datasets or creating new datasets)
• Finding what's nearby (buffering data or finding points near other features)
• Finding suitable locations or paths (running Spatial Analyst tools such as Weighted Overlay and Cost Path)

Overlaying Data (Union vs. Intersect)
• Union operation computes a geometric intersection of the Input Features. All features will be written to the Output feature with the attributes from the Input Features, which it overlaps.
• Intersect operation computes a geometric intersection of the Input Features. The Feature or portions of features which overlap in all layers and/or feature classes will be written to the Output Feature Class

Extracting Data
• Extraction by shape: extracts or selects cells based on the specified shape. You have the option to extract the cells that fall within or outside the shape. You can extract by a circle, rectangle, or polygon.
• Extraction by attribute: allows you to extract or select a set of records/features that meet a
specified attribute query.

INTRODUCTION TO ARCTOOLBOX
The ArcToolbox Windows
• Variety of Geoprocessing tasks are completed easily and efficiently using ArcToolbox.
• You can open ArcToolbox from ArcCatalog or an ArcMap document by clicking the icon.
• You can have your own Geoprocessing setting by creating a customized ArcToolbox and rename it to your name.
Right click on ArcToolbox New Toolbox Type in name

The Clip Tool
• Can be found in the Analysis Toolbox
• The Clip Tool can handle a variety of data types such as shapefiles, personal geodatabase feature classes, ArcSDE feature classes and coverages
• Can be used to exclude unwanted data from a dataset.

The Buffer Tool
• Can be found in the Analysis Toolbox and Coverage Toolbox
• The Buffer Tool can handle a variety of data types such as shapefiles, personal geodatabase feature classes, ArcSDE feature classes and coverages
• You can use the Buffer tool to identify an area within a specified distance around a feature

The Buffer Tool (cont’)
•School layer is used as an input dataset.•Specified distance is defined as 1 mile around the school point.•Dissolve all the buffers into 1 feature and remove all overlaps.
