GEODE (Geo-Data Explorer) “http://geode.usgs.gov” is an internet-based, USGS data delivery system that provides digital information to the desktops of clients and users by means of an innovative geographic information system (GIS) technology. A custom GIS interface allows policy-makers, land and resource management decision makers, educators, private industry personnel, and others to search for maps and databases, create custom map and data downloads, control map appearance, and display multiple layers of data for analysis.

GEODE consolidates data from a variety of sources in order to simplify the data mining and decision making process. Information on energy, volcanoes, earthquakes, geologic maps, climate change, ecosystems, minerals, coastal, and marine issues may be combined with additional data layers such as satellite imagery, digital elevation models, transportation systems, census tracts, and population data.

The application provides an avenue for fast, accessible, spatial research and analysis such as resource estimates and risk or hazard assessment without the need for special hardware, software, or training.
