STREET NETWORK & FEATURE EXTENSION FILES (SNFEF) - 1996 only

Description - User Guides - Datasets - Example - back to Geographic Census Data Index

Description:

The new Street Network and Feature Extension Files combine the 1996 Street Network Files (SNFs) with a road and feature network taken from the digital National Topographic Data Base files (NTDB) produced by Geomatics Canada, Natural Resources Canada. By combining these two sources of data, the SNFEFs extend the digital coverage of twenty-six (26) urban centres partially covered by the SNF to provide full digital coverage of all census tracted CMAs/CAs.

SNFEFs also provide coverage for three new tracted CAs not covered at all by Street Network Files. The NTDB portions of the 1996 SNFEF cover 298 census subdivisions, representing a population of approximately 1.9 million people. The SNFEFs (NTDB extensions joined to the 1996 SNFs) cover 642 CSDs and approximately 19.8 million people or 68% of the total population of Canada.

The extended coverage included in the SNFEFs does not include all the features and attributes of the SNF (notably, address ranges are missing). For this reason, the SNFEFs, and in particular the extended portion based on NTDB data, were created for mapping and display purposes only. Further information on this is provided in section 4.1 Lineage of the User Guide (below).
