Typically the most current and detailed data were collected for various regions of the state or for unique mapping efforts (farmland, wetlands, riparian vegetation). Decision rules were developed that controlled which layers were given priority in areas of overlap. Cross-walks were used to compile the various sources into the common California Wildlife Habitat Relationships (CWHR) system classification. Data sources had unique scale/resolution, multi-source data provided as 100m GRID.No single source exists that adequately captures the statewide distribution and diversity of land cover. To address the range of issues required in the 2002 Assessment, FRAP compiled best available land cover into a single source.Potential users are encouraged to visit the FRAPVEG site (http://frap.cdf.ca.gov/projects/frap_veg/index.html), which has detailed documentation on methodology,links to sites with the source data used in FRAPVEG, update schedule, etc. FRAPVEG statewide and county maps are available for download as well.
