Map Algebra is a way to perform spatial analysis by creating expressions in an algebraic language. With the Raster Calculator tool, you can easily create and run Map Algebra expressions that output a raster dataset.
The syntax rules for the Map Algebra expressions are similar to the syntax you may already be familiar with in previous versions of ArcGIS. The Raster Calculator is the solution for Map Algebra as a geoprocessing tool in ArcGIS 10.
Builds and executes a single Map Algebra expression using Python syntax.
