CanTopo datasets in GeoPDF and GeoTIFF format are georeferenced according to the 1983 North American Reference System (NAD 83). Approximately 2,234 datasets (maps) at scale of 1:50 000, primarily covering northern Canada, are available. ĜanTopo: Digital raster maps produced mainly from the GeoBase initiative, NRCan digital topographic data, and other sources.These maps are georeferenced according to the 1983 North American Reference System (NAD 83). ĜanMatrix - Georeferenced: Raster maps produced by scanning topographic maps at scales of 1:50 000 and 1:250 000.ĜanMatrix - Print Ready: Raster maps produced by scanning topographic maps at scales from 1:25 000 to 1:1 000 000.The combination of CanMatrix and CanTopo data provides complete national coverage. In all cases, they accurately represent the topographical data available for the date indicated (validity date). The georeferenced maps can be used in a Geographic Information System (GIS). Several editions of paper maps have been produced over time in order to offer improved products compared to their predecessors in terms of quality and the most up to date information possible. Natural Resources Canada's (NRCan) topographic raster maps provide a representation of the topographic phenomena of the Canadian landmass. It may not meet current government standards. Digital Topographic Raster Maps, 1944-2012 This group of maps, which includes the CanMatrix and CanTopo collections, is now a legacy product that is no longer maintained.
