ArcView Spatial Analyst provides a broad range of powerful spatial modeling and analysis features previously not available to desktop users. It allows you to create, query, map, and analyze cell-based raster data and to perform integrated vector–raster analysis. ArcView Spatial Analyst includes ESRI's ModelBuilder technology for building and sharing spatial models.

With Spatial Analyst, you can:

• Convert feature themes (point, line, or polygon) to grid themes.
• Create raster buffers based on distance or proximity from feature or grid themes.
• Create density maps from themes containing point features.
• Create continuous surfaces from scattered point features.
• Create contour, slope, and aspect maps and hillshades of these surfaces.
• Perform cell-based map analysis.
• Perform Boolean queries and algebraic calculations on multiple grid themes simultaneously.
• Perform neighborhood and zone analysis.
• Perform grid classification, display, and more.
