The National Geographic Database is a spatial database that contains the road network in Canada, as well as road attributes (name, type, direction, class, and address ranges where available).

See Appendix C. • Significant improvement in terms of data quality and relevance. This release of the Road Network File contains road network updates made between January 1, 2001 and June 2005 to reflect the situation in the field as accurately as possible. • New partnership developments. The primary opportunities for collaboration involve joint work on the development of datasets facilitating business operations of partnering agencies. Recent partnership agreements include: Nova Scotia – Have signed a partnership agreement where provincial road network and address register information will be provided to the National Geographic Database. Successful inclusion of these data into production is being used to refine the nature of agreements and technical specifications for use in negotiation with other agencies, such as Ontario, British Columbia, Natural Resources Canada, and Canada Post Corporation. ________________________________________________________________________ Statistics Canada 4 Catalogue No. 92-500-GIE 2005 Road Network File Reference Guide Table of contents What’s new? ................................................................................................................ 4 Table of contents ......................................................................................................... 5 1.
