A LARGE MAP(1.9 mb) version of the image above is also available for viewing. All of the Canadian topographic(land) pixels on these images bounded by 44N and 43.25N, 80.5W and 77.5W were generated from a Geological Survey of Canada(GSC) 30 meter gridded dataset. The 30 meter gridded data can be obtained from the GSC and other images were generated from this data by the GSC. All of the other areas on these maps were generated from the gridded data on this CD-ROM.
