As a GIS modeler, this is the central tool set you'll use for analysis and modeling. These tools form the foundation for all spatial modeling and geoprocessing. Of the three main types of GIS data (raster, vector, and TIN), the raster data structure provides the richest modeling environment and operators for spatial analysis.

The following operations and more are possible using the tools available with ArcGIS Spatial Analyst.

• Provide analysis on all raster and vector formats supported by ArcGIS
• Offer support for selection on raster and feature inputs (on-the-fly masking)
• Deliver on-the-fly reprojection during analysis
• Provide graphical modeling environment

• Offer numerous graphic user interface and customization approaches to analysis tools
• Create raster buffers based on distance or proximity from features or rasters
• Generate density maps from point features
• Create continuous surfaces from scattered points or contours
• Derive contour, slope, and aspect maps and hillshades of surface

• Perform cell-based map analysis
• Simultaneously execute Boolean queries and algebraic calculations on multiple inputs
• Perform neighborhood and zonal analyses
• Do discrete cell-by-cell analysis
• Perform grid classification and display
• Derive surface and groundwater hydrologic parameters
• Perform generalization and data cleanup
• Provide great developer tools

• Query and Data Exploration
• Density Mapping
• Distance Analysis
• Surface Interpolation
• Surface Analysis
• Map Algebra/Raster Calculator
