The California Mapping Coordinating Committee identified the need for a single standard statewide source for 2000 census block data. The original 2000 Census TIGER data is distributed by county. The county boundaries do not match USGS county linework but do edgematch seamlessly. CDF, working under direction of CMCC, merged all county files into a single statewide data layer.The purpose of the Census 2000 Block Data is to provide a seamless statewide GIS layer of census blocks with associated attributes.California Dept. of Forestry and Fire Protection (CDF)20020101block00vector digital datahttp://www.dot.ca.gov/hq/tsip/gis/datalibrary/gisdatalibrary.htmlground condition20001231-124.482003-122.34017242.00104738.667506-124.482003-122.34017238.66750642.001047Shapefile Caltrans TSI/GIS Data Branch Metadata Coordinator mailing and physical address Sacramento CA 95814

Downloadable Data14.27314.273 The original Census TIGER linework is distributed by county. The county boundaries do not match USGS county linework but do edgematch seamlessly with each other. We imported data in Decimal Degrees to maintain the original coordinates. Before further processing, the fuzzy tolerance was set to 0.000000000001. We dissolved the feature class on the items FIPS_CTBL and WATER to remove TIGER roads and streams that split census blocks into multiple polygons. Although most polygonal water features have unique FIPS_CTBL codes, some share their code with a block and therefore cannot be uniquely identified. Remaining extraneous arcs (dangles) were removed by selecting those arcs where LPOLY# was the same as RPOLY#. We detected no slivers after mapjoining and the number of unique census blocks in the final coverage matches the official number from the Census Bureau. We projected the entire statewide coverage into Teale Albers projection. Data from the SF1 file joined to the .PAT with no unmatched records. Some block boundary arcs are hydrography or road features. We maintained the TLID from TIGER so that the arcs can be linked to the arc feature databases. Because adjacent counties had duplicate county arcs, only one arc was maintained and attributes from the two arcs were merged. The remaining arc was assigned a NEW_TLID (the negative ID of one of the original arcs). This new ID will be relatable to the statewide TIGER Hydro and Roads feature classes when those are complete.2006061313282100unknownUnknownunknownCalifornia Dept. of Forestry and Fire Protection (CDF)20020101computer file20001231ground conditionCDFCalifornia Dept. of Forestry and Fire ProtectionSome block boundary arcs are hydrography or road features.
