A vector map is a database that describes
the road network, i.e. the information needed for a route
planning system to 'know' how to find the route
through a road system.

A raster map is a picture. This gives only image information
and can not be used for computerised planning tools in any useful
way. The only applications that can have a meaningful usage of raster
maps is the Tracking system that can use them to display vehicles
and a vehicle scheduling system to put co-ordinates on customers manually
by pointing in the map. The solution providers on the market are
doing their best to confuse the user in this case. There are actually vehicle
scheduling systems on the market using raster maps, which means
that the system shows a good looking map with roads, coastlines,
mountains etc, but cannot actually provide any useful vehicle scheduling
calculations beyond 'crow-fly' distances.
All DPSvehicle routing and scheduling is based on vector maps with
high accuracy for route planning.
