Mapper is optimized for fast drawing of maps on the screen.
Main features With Mapper you can compose maps by adding map layers and by setting properties for the display of the layers, as well as by adding data for thematic layers. Mapper is designed to be an easy to use tool for visualization and analysis of time dependant data on geographic maps. Because GIS programs are usually not optimized for fast drawing on the screen, Mapper is much faster in redrawing. This allows you to show movies of changes in time on your maps. Mapper is not intended to be a replacement for GIS since it doesn't include standard GIS functions such as digitizing, overlays, projections and so forth.
