The Alberta Township File identifies land (section, township, range) in a grid format known as Dominion Land Survey (DLS) system. It is a graphic representation of these section boundaries (approximately 1 mile X 1 mile). The file contains Section Boundary, Section Name, Original Road Allowance and Quarter Section attribute information.

The polygons in this file represent the section boundaries determined in 1997 by examination and review of all registered legal plans in The City of Calgary. Each section within the city limits are defined by eight quarter section pins and also boundary cadastral stations. The line work was created in 2006 from data which was formally released to The City in 1997.

City Planning Sectors are defined by groupings of community districts and/or transportation zones making up the Center, North, Northeast, East, Southeast, South, West and Northwest Sectors. Planning Sector boundaries extend to the city limits.
