ArcView Spatial Analyst is well-suited for providing solutions to problems that require distance or other continuous surface modeling information to be considered as part of the analysis.
The program can generate the appropriate surface representation of information from a variety of existing data sources, and can derive new information from the overlay of multiple theme types.
The results are then used to suggest possible solutions to the original problem.
