Geology Ontario provides unprecedented access to the information holdings of the Ontario Geological Survey. Rich spatial and attribute search functionality facilitates the rapid discovery of information in over 85,000 reports representing over 2,000,000 pages and 168,000 maps from OGS publications and client submitted mining assessment files. In addition, hundreds of digital products containing field data, geophysical surveys, geochemical analyses and geochronological measurements are available for download.

Designed and built on the same technologies as the internationally recognized Crown Land Automated Internet Map System (CLAIMaps), citizens can generate multi-thematic maps at select scales and link in map services from other jurisdictions and organizations. Rapid dissemination of geoscientific research and historic information promotes sustainable development initiatives and the responsible use of the Province's wealth of natural resources.

For searching on its public site, www.ontario.ca/geology, Geology Ontario integrated the dtSearch Text Retrieval Engine. “dtSearch has successfully indexed millions of our pages, including approximately 168,000 maps,” said Brian Berdusco, M.Sc., GIS Project Manager. “The speed at which results are returned is blazing. Thank you for making an excellent product that does an exceptional job at helping our citizens discover content in our document repository, a repository that reflects publications released since 1891.”
