Description:

The Skeletal Road Network Files (SRNFs) are disseminated to provide geographic reference information for the 2001 Census data. They can be used to reference the boundaries of the geographic areas by which Census data are tabulated.

The Skeletal Road Network File contains selected roads (with road names, but no addresses) that are derived from the Road Network Files. The selected roads are ranked according to four levels of detail. The different levels of detail are suitable for mapping at small to medium scales. The Skeletal Road Network Files can be used to provide some roads for cartographic reference when producing thematic maps with the Cartographic Boundary Files.

The positional accuracy of the Skeletal Road Network File does not support cadastral, surveying or engineering applications.

Skeletal Road Network Files provide full digital coverage for Canada. There are 59 standard Skeletal Road Network Files:

• Canada
• 10 Provinces and 2 territories
• 27 census metropolitan areas
• 19 census agglomerations with census tracts

The Skeletal Road Network Files replace the 1996 Skeletal Street Network Files, a similar product available only for the large urban centres of Canada.

Comparisons to the 1996 Skeletal Street Network Files

Differences between the files are:

• Roads in the Skeletal Road Network Files have been ranked to allow for mapping at four levels of detail. Ranks 1, 2 and 3 on the Skeletal Road Network Files show roads of national and provincial significance. The 1996 Skeletal Street Network Files generally contain only the type of roads that form rank 4 in the 2001 Skeletal Road Network Files.
• Skeletal Road Network Files contain more roads and road names.
• The positional accuracy of the Skeletal Road Network Files has been improved. Much of the network is re-aligned to match the National Topographic Data Base. Skeletal Road Network Files are available in NAD83. Skeletal Street Network Files are available in NAD27.
• The 1996 Skeletal Street Network Files contain road network information collected during the 1996 Census enumeration process. The 2001 Skeletal Road Network File does not contain road network information collected during the 2001 Census.
