Collaborative Database Effort for Geology

Building a multi-map, multi-user GeMS database

The Alaska Division of Geological & Geophysical Surveys (DGGS) has undertaken the challenge of developing a multi-map, multi-user database model based on the single-map GeMS geologic map schema developed by the USGS and state geological surveys. The new multi-map model is intended for national use, as is a pilot data-sharing protocol to be developed with the model. Over the next three years, DGGS is seeking interested individuals to take part in discussions via teleconferences to provide input on the needs of geologic surveys and other organizations and help develop the specifications of the database model and data-sharing protocol. A multi-map geodatabase will help DGGS meet the future goal of a 1:100,000-scale Alaska compilation, and provide a vehicle for other geologic surveys and agencies to organize and share their own geologic data.
