2 Choice of vector, raster or combined forms of spatial database
The choice of vector, raster, or combined, forms for the spatial database may be determined by the GIS in use.

The base map is the most accurate spatial database within a data system. Base maps tend to be streets, parcels and other fundamental layers.

Modeling: Applying structured rules and procedures to one or more spatial database overlays to conduct spatial and/or network analysis to derive new information to aid in problem solving and planning.
