Surveying is the precise science of determining the positions of, and the distances between, points in 2D [two-dimensional] and 3D [three-dimensional] space. There is a big difference between aerial photography and surveying. Surveys provide critical information that enables informed decision making ranging from construction site planning, to design and upkeep of infrastructure, to delineating cadastral property boundaries, and more. A drone survey is simply a survey conducted from overhead using a drone.  3, record 1, English, - drone%20surveying

Ce programme fournit les connaissances permettant de comprendre les risques naturels au Canada, par exemple les séismes, les orages magnétiques et les glissements de terrain ainsi que les conditions géologiques telles que la présence de pergélisol ou de composés métalliques naturels. Cette information est également vitale pour la résolution de problèmes liés à l'environnement par exemple le changement climatique et la pollution, pour l'exécution d'évaluations environnementales et pour la mise en valeur durable de la masse continentale du Canada.
