Data Source: The data was downloaded from the Lake County, CA GIS portal, the 'parcel.shp' and 'zoning.shp' were spatially joined. Data was enriched with Fire Hazard Zone, Flood Risk Zone, Fault Zones, Landslide Risk, Liquifaction Zones, Drought Conditions, and the potential for Renewable Energy (Solar Radiation and Wind Speed) layers, in addition to the layers provided by the county. The table schema is detailed below.

This shapefile contains tax rate area (TRA) boundaries in Lake County for the specified assessment roll year. Boundary alignment is based on the 2017 county parcel map. A tax rate area (TRA) is a geographic area within the jurisdiction of a unique combination of cities, schools, and revenue districts that utilize the regular city or county assessment roll, per Government Code 54900. Each TRA is assigned a six-digit numeric identifier, referred to as a TRA number. TRA = tax rate area number

LiDAR (Light Detection and Ranging) discrete-return point cloud data are available in the American Society for Photogrammetry and Remote Sensing (ASPRS) LAS format. The LAS format is a standardized binary format for storing 3-dimensional point cloud data and point attributes along with header information and variable length records specific to the data. Millions of data points are stored as a 3-dimensional data cloud as a series of x (longitude), y (latitude) and z (elevation) points. A few older projects in this collection are in ASCII format. Acquired LiDAR data over an Area of Interest (AOI) entire of Orange County California. The acquisition plan entailed a nominal point spacing of 1.76 points per meter square and a side lap of 40% between flight lines. The AOI covers 696 square miles.

The 17,158 acre Johnson Valley project area is located in San Bernardino County, 32 miles east of Victorville, CA bisected by highway 247. The fine-scale vegetation map was created as part of a collaborative project between the United States Geological Survey (USGS) and the Vegetation Classification and Mapping Program of the California Department of Fish and Wildlife (CDFW) to show the correlation between vegetation and geomorphology. The vegetation mapping types are based on the vegetation classification that was developed for the larger Desert Renewable Energy Conservation Plan (DRECP) mapping project (CDFW 2013). The vegetation classification was developed using a compilation of data collected for several projects including Anza-Borrego Desert State Park and Environs (Keeler-Wolf et al. 1998), the Mojave Desert Ecosystem Program''s Vegetation Database (Thomas et al. 2004), Vegetation of Joshua Tree National Park (La Doux et al. 2013), and Vegetation Classification and Mapping at Lake Mead National Recreation Area, Mojave National Preserve and Death Valley National Park (in progress, draft as of 2014).

CDFW BIOS GIS Dataset, Contact: Erin Zulliger, Description: Migration line locations for Rocky Mountain elk (Cervus canadensis nelsoni) from the West Goose Lake herd, Modoc County, California, and Lake and Klamath Counties, Oregon. Migration lines were developed in Migration Mapper using GPS locations from collared elk.

1:24,000 scale Geology of the South Lake Tahoe Quadrangle, Douglas County, Nevada, Alpine and Eldorado Counties, California, NBMG, South Lake Tahoe Folio 2Ag. Detailed geologic mapping by H. F. Bonham Jr., and J. L. Burnett. Geology of the South Lake Tahoe 7.5' Quadrangle, Douglas County, Nevada, Alpine and Eldorado Counties, California, with description of 25 geologic units. The GIS work was in support of the U.S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for the printed geologic map. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross-sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends.

This geologic map database for the El Mirage Lake area describes geologic materials for the dry lake, parts of the adjacent Shadow Mountains and Adobe Mountain, and much of the piedmont extending south from the lake upward toward the San Gabriel Mountains. This area lies within the western Mojave Desert of San Bernardino and Los Angeles Counties, southeastern California (see Fig. 1). The area is traversed by a few paved highways that service the community of El Mirage, and by numerous dirt roads that lead to outlying properties. An off-highway vehicle area established by the Bureau of Land Management encompasses the dry lake and much of the land north and east of the lake. The physiography of the area consists of the dry lake, flanking mud and sand flats and alluvial piedmonts, and a few sharp craggy mountains.

This digital geologic map database, intended for use at 1:24,000-scale, describes and portrays the rock units and surficial deposits of the El Mirage Lake area. The map database was prepared to aid in a water-resource assessment of the area by providing surface geologic information with which deepergroundwater-bearing units may be understood. The area mapped covers the Shadow Mountains SE and parts of the Shadow Mountains, Adobe Mountain, and El Mirage 7.5-minute quadrangles (see Fig. 2). The map includes detailed geology of surface and bedrock deposits, which represent a significant update from previous bedrock geologic maps by Dibblee (1960) and Troxel and Gunderson (1970), and the surficial geologic map of Ponti and Burke (1980); it incorporates a fringe of the detailed bedrock mapping in the Shadow Mountains by Martin (1992). The map data were assembled as a digital database using ARC/INFO to enable wider applications than traditional paper-product geologic maps and to provide for efficient meshing with other digital data bases prepared by the U.S. Geological Survey's Southern California Areal Mapping Project.

This shapefile contains tax rate area (TRA) boundaries in Lake County for the specified assessment roll year. Boundary alignment is based on the 2017 county parcel map. A tax rate area (TRA) is a geographic area within the jurisdiction of a unique combination of cities, schools, and revenue districts that utilize the regular city or county assessment roll, per Government Code 54900. Each TRA is assigned a six-digit numeric identifier, referred to as a TRA number. TRA = tax rate area number

This intensity raster depicts the aboveground LiDAR return to the total count LiDAR return and provides a ratio of the two from 0.0 to 1.0, where 0.0 represents no canopy and 1.0 very dense canopy. Each image corresponds to a 37,800-square-foot tile. Each pixel is 3 feet and represents an average intensity for that area. The specified coordinate system for this dataset is California State Plane Zone II (FIPS 0402), NAD83 (2011), with units in US Survey Feet for horizontal, and vertical units are NAVD88 (12A) US Survey Feet. The dataset encompasses all of Sonoma County. WSI collected the LiDAR and created this data set for the Sonoma County Vegetation Mapping and LiDAR Consortium.

Light Detection and Ranging (LiDAR) measures the return time of a laser light to reflect off objects on the ground to determine surface and ground elevations and topography. Grey County acquired LiDAR for the Georgian Bay lake fringe watersheds of Grey County in 2019 in collaboration with the Grey Sauble Conservation Authority and the Town of the Blue Mountains.

This LiDAR elevation data is publicly available for non-commercial use to agencies such as any municipality, contractor working for a member municipality or a partner(s) for a specific project, educational institution, non-profit agency or individual for research purposes. Any agency who use the data for commercial use can purchase the data at a cost of $250 per 1 square kilometer tile. The data includes Calibrated and Classified Raw Data in LAS format, Digital Elevation Model (DEM) grid files in elevation (TIF format) with cell size of 1m, Digital Surface Model (DSM) grid files in elevation (TIF format) with cell size of 1m, and 0.5m contours (SHP format).
