s (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 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 GIS with Canadian datasets benefited land-use management and environmental impact

The Canadian government and Tomlinson began working towards the development of a national program after a 1962 meeting between Tomlinson and Lee Pratt, head of the Canada Land Inventory
Canada Land Inventory
The Canada Land Inventory is a multi-disciplinary land inventory of rural Canada.Conceptualized in the early 1960s by the Department of Forestry and Rural Development , the CLI was a federal-provincial project that lasted from 1963 to 1995 and produced maps which indicated the capability of land...

(CLI). Pratt was charged with creation of maps covering the entire region of Canada's commercially productive areas by showing agriculture, forestry, wildlife, and recreation, all with the same classification schemes. Not only was the development of such maps a formidable task, but Pratt understood that computer automation may assist in the analytical processes as well. Tomlinson was the first to produce a technical feasibility study on whether computer mapping programs would be viable solution for the land-use inventory and management programs, such as CLI. He is also given credit for coining the term geographic information system and is recognized as the "Modern Father of GIS."

CGIS continued to be developed and operated by the Canadian government until the late 1980s, at which point the widespread emergence of commercial GIS systems slowly rendered it obsolete. In the early 1990s, a group of volunteers successfully extracted all of the data from the old computer tapes, and the data made available on GeoGratis.
