The Groundwater Information Network (GIN) aims to improve knowledge of groundwater systems and enhance groundwater management through increased access to standardized groundwater information. GIN connects water well databases from British Columbia, Alberta, Manitoba, Ontario, Québec and Nova-Scotia, and provides some key aquifer information from Natural Resources Canada. The information can be accessed by clicking on the link above. It can then be viewed over a map of Canada, queried one well or aquifer at a time, and multiple items can be downloaded in a common structure using a variety of convenient digital formats such as GWML (Groundwater Mark-up Language), Excel, and Google Earth. The information is accessed dynamically from its host location using open geospatial information standards, and then translated on-the-fly to the selected output format.
