What kind of data can I use with ArcGIS Spatial Analyst?
ArcGIS Spatial Analyst can do analysis on any raster format supported by ArcGIS as well as any ArcGIS feature theme including ArcInfo coverages. ArcGIS Spatial Analyst also gives you the capability to convert feature classes, such as coverages, shapefiles, geodatabases, CAD files, and Internet data, to raster format for more advanced spatial analysis. ArcToolbox has additional tools that allow conversion of many other data formats into formats that can be used directly by ArcGIS and, therefore, ArcGIS Spatial Analyst.
