Allan D. Hollander, Information Center for the Environment, University of California, Davis 20101015 2010 Version Davis, California Information Center for the Environment, University of California, Davis This map coverage augments the 2002 Multi-Source Land Cover dataset produced by the California Department of Forestry and Fire Protection to include categories for agricultural land cover types as well as urban boundaries complete to 2008. The agricultural information is derived from the Department of Water Resources land cover mapping as well crop information from pesticide use reports produced by the Department of Pesticide Regulation. The agricultural land cover classes use a subset of the DWR land cover classes, and the other land cover classes use the California Wildlife Habitat Relationships classification. Urban land use changes since the 2002 map were identified by combining the urban boundaries indicated in the Department of Conservation Farmland Mapping Program and urban land use types in the 2001 National Land Cover Dataset. This map supplements existing landcover maps of California to provide additional information about agricultural land use type and current urban condition.

Davis California 95616 (530)-752-6303 adhollander@ucdavis.edu This dataset has been visually inspected to ensure that source datasets have been correctly merged. Spatial coverage is complete across all of California. California Department of Forestry and Fire Protection 2002 http://frap.cdf.ca.gov/projects/frap_veg/index.asp online 2002 Ground Condition MSLC This was the base layer giving land cover information for natural regions of the state. California Department of Conservation, Division of Land Resource Protection, Farmland Mapping and Monitoring Program 2010 http://www.consrv.ca.gov/DLRP/fmmp/map_products/index.htm online 1984 2010 Ground Condition FMMP This layer provided information on current urban boundaries. California Department of Pesticide Regulation 2007 http://calpip.cdpr.ca.gov/cfdocs/calpip/prod/infodocs/aboutpur.cfm online 2005 Ground Condition PUR This database of pesticide usage provided spatial information on crop type by section. U.S. Geological Survey 2007 http://www.mrlc.gov/mrlc2k_nlcd.asp online 2001 Ground Condition NLCD2001 This layer provided additional information on urban cover. California Department of Water Resources 2008 http://www.landwateruse.water.ca.gov/basicdata/landuse/landusesurvey.cfm online 1990 2008 Ground Condition DWR This set of coverages from DWR provided information on crop type for many counties in California. The county-by-county Farmland Mapping coverages were merged together. Urban boundaries were extracted from this merged layer and were rasterized to 50 m resolution. FMMP 20070507 Urban pixels (Developed low, medium and high classes, i.e. values 22,23,24) were extracted from the 2001 NLCD map and resampled to 50 m resolution. NLCD2001 20101015 The California Department of Water Resources maps agricultural land use on a county-by-county basis, doing several counties each year. In this step the most recent version of every county's dataset was merged together and the land use classes converted to the agricultural classes used by the California Wildlife Habitat Relationships system. The resultant product was then rasterized at 50 m resolution. DWR 20101015 Because the DWR land use mapping does not exhaustively cover agricultural localities of the state, another source was needed to reclassify agricultural pixels in the MSLC layer to CWHR agricultural classes. This source was provided by the Pesticide Use Reports produced by the Department of Pesticide Regulation, which is a database of pesticide applications throughout the state. This database gives information on which crop type pesticides were applied to, and is spatially referenced to the nearest section. Using a public land survey map, these crop types were identified, reclassified to the CWHR system, and then rasterized at 50 m resolution. MSLC PUR 20101015 The agricultural and urban intermediate data products above were then merged with the MSLC layer to produce the final data product.
