What are spatial data models? There are two broad categories of spatial data models. Vector data model represents phenomena in terms of the spatial primitives, or components, consisting of point, line, polygon, surfaces and volumes. Raster data model represents phenomena as occupying the cells of a predefined, grid shaped tessellation. How are models used in spatial analysis? Spatial analysis is the process of geographically modeling a problem or issue, deriving results by computer processing, and then examining and interpreting those model results. The spatial model that you create is based on a set of tools that apply operations on your...
