Point maps are created as an overlay on the map, and do not require the map to contain any specific types of objects. The point objects displayed in the thematic map are based on location information pulled from the database used.
In a point map, an icon is drawn at the centroid of each target in the study area.
Boundary maps require that the map already contains boundary objects, such as polygons, which will be used to create a thematic map.
In a boundary map, data for targets are re-aggregated using regions from a map layer.
