The accuracy for CompuStreets is higher for areas within the major urban centres because of the higher accuracy and larger scale of the source maps used. The vast majority of streets were created through a process called stereodigitizing, which constrained coordinate deviation from truth to less than 6 meters. This varied between municipalities. The display projections for both the ArcView projects and the MapInfo workspaces can be fully customized by the user. The street information included in this release of Compustreets was compiled from a variety of source materials.
Some areas are more current than others, due to the diverse nature of the source materials used.
This release reflects data updates to January 2000. The next major release will be in September 2000. Pricing CompuStreets is available most major GIS formats. Call for details.
