State-of-the-art geographic information system (GIS) and information management technologies support all manners of research and activities at the Mineral Resources Program-funded Science Centers. Development of innovative GIS, visualization, and modeling approaches applied to 2-D and 3-D geologic and geochemical modeling, web-based interactive visualization, data integration, and predictive modeling is ongoing. A variety of mineral resource geospatial products may be obtained at the Mineral Resources Online Spatial Data and USGS Publications Warehouse.

Geologic Map of Alaska

In January 2016, the U.S. Geological Survey released the first ever digital geologic map of Alaska. This map reflects more than a century of work and provides a visual context for the abundant mineral and energy resources found throughout the state. The map also is available to use in three different formats: a professional GIS database, a public interactive version via a web browser, and an...

An Inventory of Past Mine Production Footprints in Alaska, Including Land Disturbance and Potential Above-Ground Resources, Derived from 2018-2023 World Imagery

This data release contains two vector polygon shapefile datasets that delineate footprints of land surface disturbance and waste that may represent potential above-ground resources resulting from past mining in Alaska. These footprints were mapped on 2023 World Imagery at the location of currently inactive Alaska Resource Data File sites of past mining production.
