CDF-FRAP 10/14/05 02_2 vector digital data The user will cite the California Department of Forestry and Fire Protection as the original source of the data, but will clearly denote cases where the original data have been altered, updated, or in any way changed from the original condition. http://frap.cdf.ca.gov/data/frapgisdata/select.asp For Census 2000, the Census Bureau classifies as "urban" all territory, population, and housing units located within an urbanized area (UA) or an urban cluster (UC). It delineates UA and UC boundaries to encompass densely settled territory, which consists of: - core census block groups or blocks that have a population density of at least 1,000 people per square mile and - surrounding census blocks that have an overall density of at least 500 people per square mile In addition, under certain conditions, less densely settled territory may be part of each UA or UC. The Census Bureau's classification of "rural" consists of all territory, population, and housing units located outside of UAs and UCs. The rural component contains both place and nonplace territory. Geographic entities, such as census tracts, counties, metropolitan areas, and the territory outside metropolitan areas, often are "split" between urban and rural territory, and the population and housing units they contain often are partly classified as urban and partly classified as rural. Each urbanized area is assigned a five-digit Federal Information Processing Standards (FIPS) code in alphabetical order for the entire U.S. For more information see http://www.census.gov/geo/www/ua/ua_2k.html FRAP uses Urbanized Areas in the creation of the Development Footprint data. Some data classes from the USGS National Land Cover Data (NLCD) are filtered by their presence/absence inside an Urbanized Area. For example, NLCD cells that are coincident with a major highway are classified as Urban when inside a UA and as Rural Highway when outside. CEN00UA03_1 created October 14, 2005 by S. Saving. Several UAs that were missing or incorrect were fixed. CEN00UA02_1 created November, 2002 by S. Saving. Dataset initially created by importing 2000 Census Block data from TIGER files into coverages and extracting Urbanized Areas. Attribute tables attached. NOTES: 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 coverage 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. We then dissolved the statewide block coverage (CEN00BL02_1) on the items UR and UA and joined in attributes from the urbanized area names lists http://www.census.gov/geo/www/ua/uc_state_corr.txt and http://www.census.gov/geo/www/ua/ua_state_corr.txt. 2000 ground condition Complete As needed -124.578761 -113.497221 42.072455 32.416203 urban Census development urbanization California Public Data - no constraints see Citation section for additional constraints CDF-FRAP Development Specialist CDF CDF-FRAP Development Specialist mailing address
