GMEG - Geology and Geophysics
The U.S. Geological Survey has produced geologic maps since its earliest days. Over time, methods of investigation, presentation, and interpretation have changed significantly. Today, maps are produced in an array of digital formats using geographic information systems (GIS) that can be used to produce traditional "flat" geologic maps for printing, or can be used for more technical, interactive data modeling. Digital geologic information can be combined with data sets including satellite or radar imagery, biology, water, weather, social infrastructure, epidemiology, population census, or practically any other kind of spatial data.
