We have digital aerial images (air photos and orthophotos) of Carleton campus, the Ottawa-Gatineau region, and Ontario that range in years from 1958-2011. All of these resources are limited to Carleton student, staff, and faculty use unless indicated otherwise.
Canadian and international sources below are freely available for use by anyone unless otherwise noted.
For all but Canada and international, lists are in reverse chronological order with data provider (City of Ottawa or National Capital Commission) and pixel resolution noted when available. Coverage varies from year to year and from provider to provider.
It is possible to measure features on an orthophoto but not on an air photo. More information.

If you are looking for aerial imagery of a specific location, check to see if the area makes aerial imagery available via open data. Our Open Data Repositories - Canada is a good place to start.
Land Viewer provides free access to Landsat 8 and Sentinel-2 satellite datasets.
Earth Explorer from the US Geological Survey provides access to almost a dozen air photo datasets in the United States.
As with Canadian areas, you may want to check open data repositories starting with our Open Data Repositories - US and International page.
