2 foot contours acquired as part of the Los Angeles Regional Imagery Acquisition Consortium in 2006. The Digital Surface Model was acquired using LIDAR (Light Detection And Ranging), which used a laser mounted in planes that were acquiring 4-inch orthophotography data. Hundreds of millions of ground measurements were made using this system, which makes it extremely accurate. This source [...] USGS CLICK site This site is a valuable resource for downloading LIDAR and Elevation data, including recent hi-resolution LIDAR along the coastlines of the United States. Click to go to the USGS Center for LIDAR Information Coordination and Knowledge (CLICK). The Cal-Atlas site facilitates the coordinated and sustainable development, maintenance, licensing and sharing of geospatial data and web map services by California government agencies, partners and stakeholders. California government agencies work with the California GIS Council, regional GIS collaboratives and the broader California GIS community to define the data architecture, systems, standards, agreements and processes [...] Digital Elevation Model (DEM) acquired as part of the Los Angeles Regional Imagery Acquisition Consortium in 2006, and made public with the partnership of the US Geological Survey (USGS). The DEM represents bare earth, whereas a related product (DSM) contains elevations and includes buildings, vegetation, and roads, as well as natural terrain features, whereas . [...] Height data for the urban/suburban areas of the County of Los Angeles developed from information captured in 2006 by the LAR-IAC program. This height data was developed from the following two data sources: The Digital Elevation Model (DEM) which modeled the ground surface at 5-foot intervals. Click here for more information The [...] A Hillshade is a shaded relief raster from a raster. Simply, when used with maps, it provides a three-dimensional aspect to the map based upon the relief of the underlying area. A more detailed definition of a hillshade can be found here. This hillshade was computed from the 2006 Digital Elevation Model [...] Digital Surface Model (DSM) acquired as part of the Los Angeles Regional Imagery Acquisition Consortium in 2006. The DSM contains elevations and includes buildings, vegetation, and roads, as well as natural terrain features, whereas the DEM (Digital Elevation Model) represents bare earth. This dataset is one of a group of elevation related [...]
