Canada Geographic Information System

The Canada Geographic Information System (CGIS) was an early geographic information system (GIS) developed for the Government of Canada beginning in the early 1960s. CGIS was used to store geospatial data for the Canada Land Inventory and assisted in the development of regulatory procedures for land-use management and resource monitoring in Canada. At that time, Canada was beginning to realize problems associated with its large land mass and attempting to discern the availability of natural resources. The federal government decided to launch a national program to assist in management and inventory of its resources. The simple automated computer processes designed to store and process large amounts of data enabled Canada to begin a national land-use management program and become a foremost promoter of geographic information systems (GIS). CGIS was designed to withstand great amounts of collected data by managing, modeling, and analyzing this data very quickly and accurately. As Canada presented such large geospatial datasets, it was necessary to be able to focus on certain regions or provinces in order to more effectively manage and maintain land-use. CGIS enabled its users to effectively collect national data and, if necessary, break it down into provincial datasets. Early applications of CGIS benefited land-use management and environmental impact monitoring programs across Canada. In 1960, Roger Tomlinson was working at Spartan Air Services, an aerial survey company based in Ottawa, Ontario. The company was focused on producing large-scale photogrammetric and geophysical maps, mostly for the Government of Canada. In the early 1960s, Tomlinson and the company were asked to produce a map for site-location analysis in an east African nation. Tomlinson immediately recognized that the new automated computer technologies might be applicable and even necessary to complete such a detail-oriented task more effectively and efficiently than humans.
