Aerial Photography

Aerial Photograph

The Map Collection currently holds about 60,000 paper air photos, focusing primarily on London and Southern Ontario. Holdings include print photos dating from 1922 to 2001 and are filed primarily by county. Urban areas are very often found within the county coverage (ex. the town of Strathroy is included in Middlesex County). Specific urban places are also filed separately for quick reference, and are listed below. Air photos can be scanned at our scanning workstation at a resolution of your choice. Patrons should be aware of what can and cannot be copied by reviewing the Canadian Copyright Act. Copies of the Act and the agreement with the University are posted in the Map Collection. Please be aware that a 50 year copyright restriction applies.

We ask that once you are finished examining or scanning an air photo please DO NOT refile it. It should be left either on top of the air photo filing cabinets or in the return basket near the workstation.

Filed with each set is a detailed flight line index to help locate specific aerial photographs. If you experience difficulty in finding your area of interest, it may be helpful to examine an National Topographic Series (NTS) 1:50,000 map or an Ontario Base Map (OBM) 1:10,000 map to pinpoint the exact location. This can be compared to the flight line index to determine whether or not your area of interest is included in our coverage. The following lists indicate the extent of our coverage.

Access to current online imagery for Ontario is available to the UWO community through the OCUL GeoPortal.
