In 1925, the Canadian Surveyor noted that the Topographical Surveys Branch of the Department of the Interior and Royal Canadian Air Force employed a method whereby they would take photographs, and then have the surveyor use these for information as to the best route to follow with his traverse, at the same time fixing points on the ground which show in the pictures in order that the correct dimensions of features of the area mapped may be plotted from the pictures themselves;

The second advertisement continues: The rapid expansion of Canadian mining fields has called for the development of new and speedy means of transportation. Dog teams, snow tractors, railways and planes are all carrying on in commendable manner. The real exploitation has been made possible by planes, that need no roads and that cover in a few hours a journey that would take days by any other means (Canadian Mining Journal [1929]: 280).

See, for example, Canada Department of National Defence, Report on Civil Aviation for 1926 (Ottawa, 1927); Canada Department of National Defence, Report on Civil Aviation for 1927 (Ottawa, 1928). Both vertical and oblique photography had difficulty dealing with dramatic elevations, but the rolling features of the Canadian Shield did not pose serious interpretation difficulties for surveyors. Photography lifted the surveyor above the heavy bush that obscured his vision on the ground and allowed him to view the outlines of the multiple formations that dotted the Shield. Oblique photography promised to be able to cover more ground more quickly, enabling the TSB and mining companies to satisfy the demand for maps of mineral-rich areas.

Unfortunately, altitudinal measurements could be unreliable. Aircraft altimeters used barometric measurements and thus were influenced by changes in atmospheric pressure and only accurate to within a hundred feet; see Matthes, Oblique Aerial Surveying in Canada, 573. Interestingly, in his article MacLeod describes an instrument for determining the camera tilt; see his The Adjustment of Air Photographs to Surveyed Points (n. 39 above), 413-19.

In 1925, work for the Dominion Forest Service formed the largest component of the RCAF's program, but it also undertook operations in Manitoba, covering 38,000 square miles using oblique photography. In 1926, Alberta operations continued to focus on vertical photography, but in Manitoba and northern Ontario, the air force used oblique photography to cover 25,000 square miles. It also covered 24,000 square miles in northern Manitoba; see Canada Department of National Defence, Report on Civil Aviation for 1925 Ottawa, 1926, 64;

The prospector and mining engineer, their interest in the North awakened by the great discoveries of the past generation in the copper-nickel areas of Sudbury, the silver mines of Cobalt, the gold discoveries in the Yukon and at Porcupine, were also seeking better methods of transportation and exploration. The surveyor and geologist, the epic of whose work during past generations has yet to be written, urged as their first necessity, faster and easier means of transportation which would conserve their time and energy for scientific work and increase the efficiency of their service by giving a wider overlook over the country and a surer method of recording its features. Services such as the North West Territories Branch, the Department of Indian Affairs, and the Mounted Police, felt the handicap the old, slow, and arduous methods of travel imposed. All were anxious to experiment with aircraft but hesitated to embark on work so technical and so far removed from their normal duties

The implication of this section is that the RCAF had been essential in meeting those needs.
