The purpose of the Santa Clara County Interactive Map Viewer is to provide to all citizens of Santa Clara County an easy graphical means to locate places in the County, and to access information about those locations.
The Points of Interest (POI) Dataset is a digital representation of the physical geographic and commercial features across all of Santa Clara County. This dataset aims to provide accurate location information in the map. Sources: Info USA (2010), California Department Of Education (2016), Santa Clara County Combined data (2016).
The National Land Cover Database 2001 land cover layer for mapping zone 03 was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of federal agencies (www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (FWS), the Bureau of Land Management (BLM) and the USDA Natural Resources Conservation Service (NRCS). One of the primary goals of the project is to generate a current, consistent, seamless, and accurate National Land cover Database (NLCD) circa 2001 for the United States at medium spatial resolution. This landcover map and all documents pertaining to it are considered "provisional" until a formal accuracy assessment can be conducted. For a detailed definition and discussion on MRLC and the NLCD 2001 products, refer to Homer et al. (2004) and http://www.mrlc.gov/mrlc2k.asp. The NLCD 2001 is created by partitioning the U.S. into mapping zones. A total of 66 mapping zones were delineated within the conterminous U.S. based on ecoregion and geographical characteristics, edge matching features and the size requirement of Landsat mosaics. Mapping zone 03 encompasses whole or portions of several states, including the states of California. Questions about the NLCD mapping zone 03 can be directed to the NLCD 2001 land cover mapping team at the USGS/EROS, Sioux Falls, SD (605) 594-6151 or firstname.lastname@example.org.
A cadastral map is a map showing the boundaries of subdivisions of land. It is based on bearings, lengths and areas of individual tracts, for purposes of describing and recording ownership.This is four equal section of the 500 grid. Some areas on the cadastral map may also show topography, drainage, and other features relating to the value of the land and its uses. The cadastral map number is the first number used in the series of three numbers for determining the County Grid Number. The Cadastral Map layer is comprised of the County Cadastral Maps series that cover the entire County of Santa Clara. It contains 281 individual maps and numbered from west to east and from north to south. Cadastral Map No. 1 is in the northwest area of Santa Clara County. Each cadastral map covers approximately 150,000,000 square feet. The information on these maps were last updated about 1986-1988. A corner record is the means by which the re-establishment or rehabilitation of public land survey corners or other property corners may be made of record and brought to public attention.
Earthquake Fault Rupture Zones are regulatory zones around active faults (USGS 2005). The zones are defined by turning points connected by straight lines. Fault rupture zones do not correspond with Alquist-Priolo fault zones.
