Prototype Implementations of the North American Data Model Steering Committee for a Geologic Map Databaseby Ronald R. Wahl, U.S. Geological Survey, Denver, Colorado, USA The National Geologic Map Database Project (NGMDB) of the U.S. Geological Survey (USGS) has been working to implement the North American Data Model Steering Committee (NADMSC) data model in a number of software system. To: 1)obtain the functionality demanded by the model, 2) provide a seamless database of geologic map data; 3) provide versions of the data for publishing and investigative endeavors; and 4) provide web access and delivery of such data, the NGMDB has developed a number of prototype databases using object-oriented software. Additonal benefits discovered from this work are: iterative changes to the underlying data model does not change the data already in place, and the geologic features are not necessary referred to by the geometry of the feature.
