Canada - 1:10000000

Contained within the Atlas of Canada's Various Map Series, 1965 to 2006, is a bilingual map produced jointly by Natural Resources Canada and the Canadian Space Agency. The map was produced using 45 separate images taken by AVHRR sensors aboard satellites of the National Aeronautics and Atmospheric Administration (NOAA). The satellite data was enhanced so that certain major land-cover types could be more readily told apart from one another. AVHRR (Advanced Very High Resolution Radiometer) data has pixel resolution of about 1 x 1 kilometre size on the ground. The data were compiled from images taken in August 1990.
