The Harrison and others (1998) geological map was digitized and minimally attributed by Ken Sandau (Montana Bureau of Mines and Geology (MBMG)) who then provided four minimally attributed ArcInfo interchange-format files to the U.S.G.S.; Robert J. Miller (USGS) combined the faults coverage into the contact and rock unit coverage; and Helen Z. Kayser (contractor) attached and attributed an interim geologic map data model.
This digital geospatial database is one of many being created by the U.S. Geological Survey (USGS) as an ongoing effort to provide geologic information in a geographic information system (GIS) for use in spatial analysis.
Are there legal restrictions on access or use of the data?
