|This Web site contains information on activities of the National Geologic Map Database Project (NGMDB). The NGMDB is a collaborative effort primarily involving the USGS and the Association of American State Geologists. This Web site contains informal, generally time-sensitive material intended for project members, cooperators, and interested parties.|
The "DMT" workshop series provides an informal, technical setting where geological surveys can discuss more efficient and useful methods for digital mapping and GIS analysis. More information on these workshops is available.
