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 a 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 as a stand alone system by the Government of Canada until the late 1980s, at which point the widespread emergence of commercial GIS software 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.
