The National Geologic Map Database project plan identifies three principal phases [for progress reports and information, please see
These guiding concepts have been presented and discussed at numerous public meetings (e.g., see http://pubs.usgs.gov/openfile/of00-325/soller4.html).
Through a series of prototype databases, we began to build this database. When each prototype reaches maturity, results are presented for discussion at public meetings; this is an essential aspect of the effort -- to provide to the geoscience community a tangible object for discussion and reflection (e.g., "is this what we really want?"). The initial prototype was developed for 1:100,000-scale geologic map quadrangle information in the Greater Yellowstone Area. The next prototype, building on preliminary technical findings in the Yellowstone project, began in 2000, in cooperation with the Kentucky Geological Survey. That effort has matured, and has been publicly discussed (see http://pubs.usgs.gov/of/2001/of01-223/soller2.html). The next prototype is being planned; results and discussions will be posted at this site.
While these prototypes are underway, the National Geologic Map Database project is supporting some activities designed to produce National-scale geologic map information, as described elsewhere.
