How are GIS files organized?

National Topographic System (NTS) most Canadian GIS files are organized by a 1:50,000 or 1:250,000 scale grid:

Canadian Geographic Names Database  provides NTS map sheet grid, ATS location, latitude/longitude

Alberta Township System  (ATS) many Calgary and Alberta GIS files are organized by section-township-range-meridian

  • City of Calgary Alberta Township Sections zoom in and click on area of interest; in the popup box information look for ats_section_no; ex. 182415 refers to Section 18 Township 24 Range 1 West of the 5th meridian
  • LSD Finder (aka Grid Atlas) zoom and click for ATS, also UTM, latitude/longitude, and address
  • GeoDiscover Alberta navigate to your area of interest, then determine NTS or ATS by clicking on the appropriate layer
