Trent Technical
Note 99-1
Cogley (1999a) presents an algorithm for rectifying (that is, transforming to map coordinates) high-oblique aerial photographs taken with the Trimetrogon cameras which were widely used until the 1950s. Rectification of high obliques (which contain the horizon) appears to have become a lost art since the advent of high-altitude vertical aerial photographs. Being unable to use these Trimetrogon photographs quantitatively is a hindrance to the historical reconstruction of glacier change, which is unfortunate because the photographs, taken in the 1940s and 1950s, represent the dawn of recorded history for nearly all of the glaciers (and indeed, of the terrain) in the Canadian High Arctic.
