Canadian GisThere is no doubt that the success of Geographic Information Systems (GIS) lies in the abounding technological advances of the past century. The popularity, however, has risen from a bit of an unlikely source. Roger Tomlinson and the inception of a national Canadian GIS program began the long journey toward widespread use of GIS in many practical applications. 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 GIS. In the early 1950s and 1960s, Canada was beginning to realize problems associated with its seemingly endless boundaries, in combination with natural resource availability. The Canadian government therefore decided to launch a national program to assist in management and inventory of its resources. To do so, Canadian Geographic Information Systems (CGIS) was developed to assist in regulatory procedures of land-use management and resource monitoring. 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 (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 monitoring programs. Canadian GIS did not develop overnight, rather it was the combination of the right factors coming together at the right time. In 1960, Roger Tomlinson was working at an aerial survey company in Ottawa, Spartan Air Services. The company was focused on producing large-scale photogrammetric and geophysical maps. 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. Eventually, Spartan met with IBM offices in Ottawa to begin developing a relationship to bridge the previous gap between geographic data and computer services. Tomlinson brought his geographic knowledge to the table as IBM brought computer programming and data management. 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 (CLI). Pratt was charged with creation of maps covering the entire region of Canadas 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."
