TIGER data are a spatial database of roads, railroads, rivers, lakes, political boundaries, census statistical boundaries, etc. covering the entire United States. The data base contains information about feature location in latitude and longitude, name, type of feature, address ranges for most streets, and other related information. TIGER was developed at the Census Bureau to support the mapping and related geographic activities required by the census.
The source materials used in developing the TIGER data base are principally the 1:100,000 U.S. Geological Survey (USGS) topographic maps. The USGS digitized the roads, railroads, hydrographic features, and miscellaneous transportation feature layers. For the 2% of the land area covered by the major urban areas the Census Bureau substituted the GBF/DIME files. The resulting TIGER data base file is in turn updated by maps obtained from local officials and some field work done by Bureau staff.
Tiger data is available in the following formats:
- MapInfo - .TAB -- Latitude/Longitude projection NAD 83
