U.S. Census 2000 Data: TIGER Linework
- The TIGER Linework layer contains characteristics relating to roads networks, some water features (rivers and streams, canals, ferry routes, etc.), political boundaries, and other features. The road features contain address ranges that may be used in geocoding (address matching) applications. Use the CFCC field to determine the feature type. For detailed descriptions of each field, including the CFCC codes, please see http://www.census.gov/geo/www/tiger/tigerua/ua2ktgr.pdf (CFCC codes are in chapter 3). TIGER linework defines the boundaries of Census Blocks, the finest resolution of geographic boundary data developed by the U.S. Census Bureau for the 2000 Decennial Census. TIGER is an acronym for Topologically Integrated Geographic Encoding and Referencing. MassGIS has extracted and reprocessed data from the original TIGER/line files for use with its other data. Processing included import of the original data with the ArcInfo TIGERTOOL command, projection to the Massachusetts State Plane (NAD83 Meters) Coordinate system, and modification of the attribute table.
