Geochemical data from a variety of sources worldwide. Advanced search interface allows users to define many parameters to find appropriate information.

The USGS provides science about the natural hazards that threaten lives and livelihoods, the water, energy, minerals, and other natural resources we rely on, the health of our ecosystems and environment, and the impacts of climate and land-use change. Its scientists develop new methods and tools to enable timely, relevant, and useful information about the Earth and its processes.

The National Geochemical Database project assembles, reformats, corrects, and archives historical data obtained from the geochemical analysis of millions of geologic samples collected for USGS studies. These data, representing hundreds of millions of dollars' worth of USGS research, are provided to USGS researchers; other Federal agencies; State Geological Surveys and Environmental Protection agencies; mining, mineral exploration, and environmental industries; independent consultants; academicians; students; and private citizens through online portals and project collaboration.

Geospatial information from the Canadian federal government, including topographic maps and GIS data.

Datasets from the federal government, including the USGS and other agencies.

Bathymetry, earth observations from space, geomagnetic data & models, marine geology & geophysics, natural hazards, space weather & solar events.

ShareGeo Open was a repository of geospatial data, previously hosted by EDINA. ShareGeo Open has been discontinued, so its datasets have been migrated to this Edinburgh DataShare Collection, for preservation, in accordance with the agreement signed by all ShareGeo depositors.

Mindat.org has been collecting, organising, and sharing mineral information since October 2000. It is now an essential resource used daily throughout education, academia, and industry. The mindat.org database contains information on minerals and the localities they are found at.

High resolution photos of geologic formations, rocks, minerals, and interesting earth features.

Texas A&M University Library has digitized this series of maps and information published by the USGS between 1894 and 1945. Each folio in the series offers a topographic map and a geologic map of the 15' quadrangle, plus additional information particular to the map area. These maps sets offer great detail, in an easy to use online interface, although they are older.

Search for a geologic map data with keyword and map-based searching. Links are provided to online map images, where available, as well as text citations. Robust search tools allow queries of any place name or a lat/long search. Maps cover North America, primarily the United States.

Map data available for download, including US Topos (the USGS's most up-to-date topographic maps), elevation data, aerial photographs, land cover data and more.

Geologic map information from around the globe. Most maps are at approximately a 1:1,000,000 scale. Data are contributed by participating national geologic survey organizations. Coverage is still inconsistent, but growing.

View topographic maps online. Users can find locations via clicking a map or searching for a location. Maps can be printed and emailed or downloaded as images.

Map based guide allows you to click on a map location to find and download the topographic map you need.
