  • 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
