Ontario Geology Maps and GIS Data

Ontario Geological Survey's OGSEarth provides geoscience data, collected by the Mines and Minerals division, which can be viewed using user-friendly geographic information programs such as Google Earth.

OGSEarth provides data on the following topics:

  • Mining claims
  • Geology
  • Index maps
  • Administrative boundaries
  • Abandoned mines

Canada Geological Maps and GIS Data

  1. Geological Survey of Canada (GSC)
    GSC has released geological maps in digital files through the GEOSCAN online database. When searching for maps, use the Advanced search to search specifically the “A” Series maps or the Canadian Geoscience maps. The “A” Series maps are those that focus on Geology and have been recently replaced with the GSC Canadian Geoscience Map. Most of the maps from these series show the geology of a specific area at a larger scale. These are also available in paper format in the GSC “A” Seriesmap cabinetin the library. Below are some of the more general maps that cover all of Canada from the “A” Series.

​World Geological Maps and GIS Data

  1. Association of American State Geologists (AASG)
    Great website to have direct access to each US states’ geological survey and agency.
  2. United States Geological Survey (USGS)
    Resource for maps and related data about geology, hazards, earth resources, geophysics, geochemistry, geochronology, paleontology and marine geology. 85,000+ maps, images, data, and products. Data viewer allows the user to find regional geologic maps and information in the Map Catalogue and Lexicon of Geologic Names (Geolex).
  3. One Geology
    This is an international initiative of the geological surveys of the world. This groundbreaking project was launched in 2007 and contributed to the 'International Year of Planet Earth', becoming one of their flagship projects.
