Geoprocessing
Using geoprocessing to automate GIS tasks

Geoprocessing is what you use for many day-to-day GIS tasks. Geoprocessing tools perform small yet essential operations on geographic data, such as extracting and overlaying data, changing map projections, adding a column to a table, calculating attribute values, polygon overlays, and calculating optimal routes, to name a few.

There are hundreds of tools at your disposal, and you can chain together the tools using Modelbuilder, feeding the output of one tool into another. The illustration below shows a model where the input feature class is clipped to a study area and then projected to another map projection.
