Source Scale

Varies: 1:12,000 to 1:100,000

Horizontal Accuracy

Varies: The Census Bureau does accuracy tests using high-precision GPS at street intersections and documents errors per county. Not all streets have been re-aligned. Estimated accuracy range for re-aligned streets is +/- 23 to +/- 40 feet. Streets that have not been re-aligned can be over 300 feet off. Rural areas are more likely to be less accurate than urban areas.
