Colour aerial ortho photographs of The City are based on the Alberta Township Survey (ATS) sections. Photos may be used for personal or reference purposes, but may not be republished.
The 2016 orthophotos are cropped to capture imagery within the Calgary city limits with a 200 meter buffer around the city's boundary. As a result some sections may be incomplete.
