LIBRARY : COUNTY LAYER NAME : GOVOWNERSHIP COVERAGE NAME : GOVTOWNA LOCATION OF RELATED TABLE: /callib/statewide/info/arc:govtowna.lut COVERAGE DESCRIPTION: The 'GOVOWNERSHIP' layer shows classifications of land ownership and was originally digitized by the Forest and Rangeland Resources Assessment Program of the California Department of Forestry. It was then registered to the Public Land Survey coverage at Teale Data Center to ensure that coincident lines would overlay properly. It is derived from 1:100,000 Bureau of Land Management Surface Management Status Maps. Some of these maps date back to the 1970's. The most recent national forest maps and other sources were used to update the BLM maps prior to digitizing. The coverage was developed with state, regional, or county level analysis in mind. It does not included parcel level data and may not address the needs of users interested in small areas. Updates to the government ownership coverage (1995): - Expansion of National Park Service lands in Death Valley, East Mojave and Joshua Tree. - Inclusion of ownership updates in Southern California from UC Santa Barbara GAP analysis program. - Addition of many Bureau of Indian Affairs reservations. - Updates in Santa Monica Mountains from NPS, UCSB. - State and county parks in San Mateo County. - Changes in Mono Lake, Salton Sea and Chocolate Mountain areas. Updates to the government ownership coverage (1998): - Inclusion of ownership updates from Dept of Fish and Game - Inclusion of ownership updates from Golden Gate National Recreation Area, prmarily in Marin County - Minor changes from military base closures. - Minor National Forest and BLM changes resulting from California Department of Forestry and Fire Protection SRA review process. - UPDATE item in polygon and arc attribute tables expanded from 4 to 8 intergers (YYYYMMDD) Updates to the government ownership coverage (1999): - Inclusion of ownership updates from Bureau of Land Management If the user is aware of further updates or corrections, please contact us. Along with improvements to the coverage come improvements to the updating process which allows changes to be incorporated into the coverage more quickly.
