software suite that improves on mainstream GIS software in terms of graphic rendering speed, usability, database connectivity, manageability of
extremely large vector and raster datasets, cost effectivity and productivity.
Development on PlanetGIS started in 1993 and the software has been in extensive use by GIS practitioners since 1994.
excels where mainstream GIS products usually frustrate because it has
been designed specifically for those tasks used most often in a GIS.
