The City of Calgary has released a highly accurate aerial photograph taken on June 22, 2013 of the areas adjacent to the Bow and Elbow rivers. The photo is referred to as an orthophoto and was taken by a low-flying aircraft on June 22, between 8 a.m. and 9:30 a.m.
“This orthophoto is a snapshot that shows the Bow and Elbow rivers, at that particular time,” says Bruce Cullen, Director of Infrastructure & Information Services at The City. “This orthophoto does not necessarily indicate the maximum high water line or how the water got there.”
