OrbisCAD is the community precise cartography editor which allows reading shapefiles, postGIS, DXF, DGN (7.0) and DWG (2000) and writing shapefiles and postGIS. It can access any vectorial format since it is built upon GDBMS. OrbisCAD is a plugin driven application so it can be extended easily by writing plugins, creating editing tools, scripting and vectorial format drivers.
