Geographic Information Systems Canada

(CGIS) was developed in the 1960s and 1970s to assist in regulatory procedures of land-use management and resource monitoring. At that time, Canada was beginning to realize problems associated with its seemingly endless boundaries, in combination with natural resource availability. The government therefore 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 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 monitoring programs.


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 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.

What is White Supremacy? by Elizabeth Martínez
copyright Elizabeth Martínez, February 1998.
*Workshop Definition* White Supremacy is an
historically based, institutionally perpetuated system of exploitation and
oppression of continents, nations, and peoples of color by white peoples
and nations of the European continent, for the purpose of maintaining and
defending a system of wealth, power, and privilege.

The most common mistake people make when they talk about racism is
to think it is a collection of prejudices and individual acts of
