Functionality

GIS functionality uses the spatial and non-spatial attribute data in the database to answer questions about the real world (Aranoff, 1989). A typical GIS application looks at 'what if' type scenarios, ie. the implications of proposed activities at certain locations.

This sort of functionality makes it a particularly useful natural resource manager for applications such as performing Environmental Impact Assessments.
