A map type represents a grid of cells. Associated to this grid, we have a map projection, datum and registration coordinates.
There are two basic types of maps:
Maps whose cells represent classes or categories, like, vegetation type, soil type, sub-regions etc.
Maps whose cells represent values like temperature, probabilities, distances etc.
