“The 1921 Aerial Survey of Halifax”
Dirk Werle, ÆRDE Environmental Research
This illustrated talk presents the history, development, and results of aerial photography in Canada immediately after the First World War. The collections of early aerial photography in Canada and elsewhere, as well as the institutional and practical circumstances and arrangements of their creation, represent an important part of our heritage. An episode of one of the first urban surveys, carried out over Halifax, Nova Scotia, in 1921, is highlighted. Using the air photos and a digitally re-assembled mosaic of that collection as a guide, a variety of features unique to the post-war urban landscape of the Halifax peninsula are analysed and compared with records of past and current land use. The air photo ensemble is placed into the historical context with thematic maps, recent air photos, and modern satellite imagery.
