ArcGIS Spatial Analyst offers a wide range of functions and models for geographic and spatial analysis integrating raster. With Spatial Analyst, you can create and query a raster layer, perform analysis on raster and vector, enhance existing data, query data spread out over several layers and operate on vector and raster data simultaneously.

ArcGIS Spatial Analyst incorporates the following functions:

• Conversion of elements (points, lines and polygons) into Raster data
• Creation of Raster buffer areas based on distance or proximity
• Generation of density charts from points
• Creation of continuous areas from points
• Computing of maps in isolines, slope maps, orientation maps and shading maps based on DTM
• Map algebra - logical requests and algebraic calculations between Raster layers
• Area and neighbourhood analyses between Raster layers
• Cell analysis
• Raster classification
• Use of numerous standard formats such as TIFF, BIL, IMG, USGS DEM, SDTS, DTED, etc
