This collection of 767 digitized mosaics was created primarily from Aerial Photographs taken between 1949-51 by the Aerial Survey Section, Technical Division, Alberta Department of Lands & Forest. It has been suggested that these mosaics were perhaps the earliest aerial survey of the entire Province of Alberta. Interestingly, the photo collection coincided with introduction of major resource extraction initiatives which makes them a still-relevant resource for students, researchers and the general public.
