Overview
ArcGIS Spatial Analyst software provides tools for conducting sophisticated spatial analyses and creating different types of spatial models. This course covers fundamental raster data concepts and shows how to use ArcGIS Spatial Analyst tools to create, process, and analyze spatial data. Students focus on problems that are best solved in a raster environment such as surface analysis and distance measurement. The use of ArcGIS Spatial Analyst tools in the ArcGIS 9 geoprocessing framework is emphasized.
Who Should Attend
This course is designed for experienced ArcGIS users who want to conduct raster-based analysis, conversion, and editing.
