GeMS Wiki

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 Geologic Map Schema (GeMS) developed by the USGS and state geological surveys. The multi-map model is intended for national use. 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. DGGS is seeking interested individuals to take part in discussions via teleconferences to provide input on the needs of geologic surveys and other organizations, help develop the specifications of the database model, and share ideas to help the community.

Telecons or Webex will usually be held the 2nd Monday of the month. The next meeting is scheduled for Monday, May 9, 2022, 2pm ET.
