Historical Orthophotos of Alberta (circa 1950-60)
Covering the entire province of Alberta, this dataset contains georeferenced, orthophoto maps consisting of aerial photography mainly from 1949 to 1951. This set also contains some maps containing photos from 1961 to 1963. Each of the original maps covers a 1:50,000 NTS sheet at a scale of 1:63,360.
Alberta Tourism, Parks and Recreation provided the original orthophoto maps and in 2008 the former Alberta Research Council, current Alberta Innovates Technology Futures, scanned most of the maps in collaboration with the University of Alberta Map Library. The ABMI scanned last 20 missing tiles in 2015 after staff from Alberta Environment and Sustainable Resource Development (AESRD) located them. Scanning was done on an HP Designject 820 mfp scanner at a resolution of 1,000 DPI. The georeferencing was implemented by ABMI using 2.5-metre panchromatic SPOT imagery for 2012. The output resolution is at 1.22 metres.
