As the population of the Maritimes, Lower and Upper Canada grew, the economic potential of the land increased. People began to recognize mineral deposits that could be exploited and William Logan proposed the creation of the Geological Survey of Canada (GSC) in 1840 with headquarters and labs in Montreal.

Growing out of the GSC work was a need for better topographical maps--the Topographic Survey and Geodetic Surveys were created to supplement and expand the GSC’s work. The pinnacle of their 19th century work was the survey of the Prairies and Rockies as the Canadian Pacific Railway pushed westward. The surveys of the Rockies led to some innovative methods, primarily by Edouard Deville, including the photographic survey camera he developed. He later introduced aerial photographic surveys into the Topographical Survey’s work.

Because of Canada’s vast, remote territories, we became leaders in aerial survey techniques up to and including the most sophisticated digital techniques used today from aircraft and spacecraft (RADARSAT).
