The Montana Cadastral Mapping Project is a public-private sector partnership to create, maintain, and disseminate a digital GIS land ownership (cadastral) map database of the entire state. Parcels and real property are mapped and maintained by state and county cartographers. Descriptive data are derived from the Montana Department of Revenue CAMA (Computer Assisted Mass Appraisal) database.

Corpscon, Version 5.11.08 (Year 2000 compliant), is a MS-Windows-based program which allows the user to convert coordinates between Geographic, State Plane and Universal Transverse Mercator (UTM) systems on the North American Datum of 1927 (NAD 27), the North American Datum of 1983 (NAD 83) and High Accuracy Reference Networks (HARNs). Corpscon uses the National Geodetic Survey (NGS) program Nadcon to convert between NAD 27, NAD 83 and HARNs. Corpscon, Version 5.x, performs vertical conversions to and from the National Geodetic Vertical Datum of 1929 (NGVD 29) and the North American Vertical Datum of 1988 (NAVD 88). Vertical conversions are based on the NGS program Vertcon and can be performed for the continental U.S. only. Corpscon, Version 5.x, will also calculate geoid-ellipsoid separations based on the NGS program Geoid96. Geoid-ellipsoid separations can be calculated for the Continental U.S., Alaska, Hawaii and Puerto Rico/U.S. Virgin Islands.
