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 2018 orthophotos capture imagery within the Calgary city limits with at least a 2 km buffer around the city's boundary. As a result some sections beyond the city limits may be incomplete.
