This polygon shapefile depicts 5 foot elevation LiDAR grid for the County of Santa Clara, California. LiDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. The Santa Clara Valley Water District manages an integrated water resources system that includes the supply of clean, safe water, flood protection and stewardship of streams on behalf of Santa Clara County's 1.8 million residents. This layer is part of a collection of GIS data for Santa Clara County, California.The 2006 LiDAR contour shapefiles were clipped into smaller cells in order to reduce file sizes and improve ease of distribution. This coverage can be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analyses of geospatial data.
