U.S. and Canada Detailed Streets represents streets, highways, primary roads with and without limited access, secondary and connecting roads, local and rural roads, trails, roads with special characteristics, access ramps, and ferries within the United States and Canada. This data set contains road network features such as arterial classification, speed, and direction of travel. It contains address ranges for all addressable features with addresses.
Logical consistency: The shapefile is converted to SDC (Smart Data Compression) format using tools in ArcGIS. The SDC data set is then imported into a file geodatabase to verify, validate, and if needed repair the geometry. Horizontal position accuracy: While minimum positional accuracy is consistent with 1990 Census TIGER/LineĀ® files (+/- 167 feet (51 meters)), horizontal accuracy is dependent on geographic area and additional sources used to update those areas. Selected geography has been realigned to sub-12-meter horizontal accuracy. Other data details: After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
