Atlas of Canada National Scale Frameworks data are standardized national coverages of commonly used geospatial datasets at the 1:1 000 000 scale. A variety of framework layers (e.g. hydrology, roads, ferry routes, railways, administrative boundaries, census subdivisions, population ecumene, drainage areas, protected areas and Canadian place names) have been integrated so that their relative positions are correct. Hydrology (which includes coastline) is the base layer to which all others are fitted.

The Atlas of Canada 1,000,000 National Frameworks Data, Road Network is based on 1:250,000 scale National Topographic Data Base (NTDB) road and ferry route datasets which have been assembled into a national coverage and updated using various reference sources. A selection of the network suitable for use at a scale of 1:1,000,000 was extracted based on road classification and linework was smoothed. In 2003 the resulting road network layer was fitted to the Atlas of Canada National Scale Frameworks Hydrology layers. Minor adjustments were made to ensure that the correct relative positionality of this layer to the National Scale Frameworks Rail Network layer was maintained. An update to the data set was completed in 2008.

Additional Information

Purpose

The Atlas of Canada 1,000,000 National Frameworks Data are a set of integrated base map layers, which form the Atlas of Canada 1,000,000 National Frameworks Data collection. These data have been compiled at a scale of 1:1,000,000 with the primary goal being to indicate correct relative positioning with other frameworks layers rather than absolute positional accuracy.
