The Canada Land Inventory and Google Earth
Canada Land Inventory (CLI) capability with relief enhancement gives a Google Earth like visual display of one of Canada's most comprehensive knowledge bases. This digital map was prepared by Glenn W. Lelyk, specialist in Land resource Applications in the Land Resource Unit- Manitoba of Agriculture and Agri-Food Canada, University of Manitoba Campus, Winnipeg, Manitoba.
The agricultural capability classification from the 1:250'000 CLI is superimposed on a digital terrain model. The shaded relief enhances the relationships between the capability classification and the geomorphology , soils and glacial and post glacial history. The warm colored hart of the map is formed by the glacial delta of the Assiniboine river. The former glacial lake beaches, starting at the slopes of Riding Mountain National Park in the top-middle of the map image, diagonally devide the right half of the map: The glacial lake plain with lacustrine clay deposits on the east side, and a predominance of ground moraine material on the west side.

CLI overlay on Google Earth
When combined with Google Earth, the CLI"knowledge" map becomes particularly powerful as visualization of the potential of landscape ecosystems as building blocks for integrated regional planning and management. It enables broader public understanding and participation in public policy and resource management, especially for resource dependent communities.
The CLI: One of the Largest Digital Map Sources in Canada
The CLI provides a comprehensive multi-disciplinary digital data set for the settled portion of Canada, for agriculture, forestry, recreation , land use, waterfowl, ungulates and sport fish capability.
- The Geogratis web site of Natural Resources Canada provides download access to the CLI/ CGIS map base and a comprehensive description of the CLI: http://geogratis.cgdi.gc.ca/CLI/frames.html
- The following maps provide an interesting comparison of this map image with the actual CLI classification for waterfowl and agriculture.
CLI Waterfowl Capability : 62J. This is the digital "thumbnail" of the original 1:250'000 scale map stored in the Canadian Geographic Information System.
- CLI Agriculture Capability: 62G
The Canada Land Inventory was actually designed for this purpose in the late 1960's and implemented in the 1967-1977 period. The sheer size of this Federal-Provincial Inventory Program required the development and of the Canadian Geographic Information System (CGIS) the first operational GIS in the world, designed for regional planning as well as continental wide analysis.
The Canada Land Inventory System covers about 2.5 million km2 of Canada's settled lands. Digital files can be obtained from Natural Resources Canada: http://geogratis.cgdi.gc.ca/CLI/frames.html
