Enhancing AZGS’ Digital Geologic Maps with GIS Data Formats
Digital geologic maps are the currency of 21st century geology
The Arizona Geological Survey launched the Digital Geologic Map (DGM) series in 2000, and we have now published more than 120 digital maps in PDF format; all of which are freely available for download at the Arizona Geological Survey Online Document Repository. PDF maps are easier to share, store, and edit than traditional paper maps. A limitation of both PDF and paper maps, however, is that they only convey a small and static subset of all the data that our geologists collected without becoming visually overwhelming.
To address this shortcoming, we now include geodatabases that include a much fuller set of observations by our geologists and, more importantly, allow users to interactively choose the specific types of data they wish to see displayed in the map image. This additional flexibility will greatly improve the utility of our maps for our stakeholder community in federal, state, county and local government, the mining and mineral industry, emergency management, and infrastructure developers and road builders (Tables 1 and 2).
Upgraded DGM products align with the ‘National Cooperative Geologic Map Program 09‘ (NCGMP09) standards. Funding was provided by the US Geological Survey’s National Geological and Geophysical Data Preservation Program (NGGDPP) program. NCGMP09 is now referred to as GeMS – Geologic Map Schema; for additional information on GeMS, contact the US Geological Survey’s GeMS team.
This past week we finalized and released upgrades to three DGM products (Table 1). Table 1 lists the DGM #, topographic map name, and the author(s) and geologic map title of the upgraded DGMs now available for no-cost download at the AZGS Online Document Repository. (http://repository.azgs.az.gov/ ). An active link accompanies each DGM citation.
AZGS' geoinfomatics team plans to release another 2 dozen upgraded DGMs complete with geodatabases in 2020.
