Air Photos

Air Photo Search Guide

The Air Photo collection includes about one million air photos of Canada with Calgary and Southern Alberta as the primary focus. There is less inclusive coverage for northern Alberta and the other western provinces and territories. Coverage is spotty for other areas of Canada. Air photos have been taken at various scales and years; City of Calgary coverage starts in 1924.

Air photos and flight line indexes are organized in sets according to the 1:250,000 National Topographic System (NTS) map sheet grid . Search for your location and then “Use ‘Toggle NTS Grid’ button.

University of Calgary air photo sets are arranged as in the following example: 82 P 40 1950 consists of air photos taken within the NTS map sheet 82P, flown at a scale of 1:40,000 in 1950. The air photo database can be searched by the 1:50,000 NTS map sheet numbers to determine which air photo sets have coverage for that map sheet.

Digitized Air Photos
Approximately 32,000 historic air photos have been digitized and are available online . Only copyright cleared air photos (more than 50 years old) can be digitized. You can also search for them in conjunction with the print air photos .
