The USGS Astrogeology Mapping, Remote-sensing, Cartography, Technology, and Research (MRCTR, pronounced "Mercator") GIS Lab provides web-based resources aimed at the planetary research community. The lab supports Geographic Information Systems (GIS) graphical, statistical, and spatial tools for analyses of planetary data, including the distribution of planetary GIS tutorials, tools, programs, and information. We maintain planetary GIS databases consisting of peer-reviewed digital geologic maps, feature maps, topography, and remote-sensing data under the scientific oversight of the NASA Geologic Mapping Subcommittee (GEMS). In addtion the lab supports and encourages geospatial open standards.

News: Next hand-on GIS training workshop for July 29-31, 2015 has been announced.
