DWG and DXF Format

AutoCad software is required to open this type of file. You can also import these into a GIS compatible application such as ArcView, MapInfo, or MicroStation. The file conversion is different though depending on the software application used.

GeoDatabase Format

Arcview 9.2 is required to open this type of file. All the files are saved in an .mdb Geodatabase that can only be opened with the latest version of Arcview, ArcEditor, or ArcInfo.
