NLCD 2004 Land Cover California Subset

The U.S. Geological Survey (USGS), in partnership with several federal agencies, has developed and released five National Land Cover Database (NLCD) products over the past two decades: NLCD 1992, 2001, 2006, 2011, and 2016. The 2016 release saw landcover created for additional years of 2003, 2008, and 2013. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nation’s land resources, the USGS has designed a new generation of NLCD products named NLCD 2019. The NLCD 2019 design aims to provide innovative, consistent, and robust methodologies for production of a multi-temporal land cover and land cover change database from 2001 to 2019 at 2–3-year intervals. Comprehensive research was conducted and resulted in developed strategies for NLCD 2019: continued integration between impervious surface and all landcover products with impervious surface being directly mapped as developed classes in the landcover, a streamlined compositing process for assembling and preprocessing based on Landsat imagery and geospatial ancillary datasets; a multi-source integrated training data development and decision-tree based land cover classifications; a temporally, spectrally, and spatially integrated land cover change analysis strategy; a hierarchical theme-based post-classification and integration protocol for generating land cover and change products; a continuous fields biophysical parameters modeling method; and an automated scripted operational system for the NLCD 2019 production. The performance of the developed strategies and methods were tested in twenty composite referenced areas throughout the conterminous U.S. An overall accuracy assessment from the 2016 publication give a 91% overall landcover accuracy, with the developed classes also showing a 91% accuracy in overall developed. Results from this study confirm the robustness of this comprehensive and highly automated procedure for NLCD 2019 operational mapping. Questions about the NLCD 2019 land cover product can be directed to the NLCD 2019 land cover mapping team at USGS EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.

Each record represents a line, or linear scattered occurrence of red sesbania.
Greater Sage-grouse Range - NE CA - 2005 [ds96]

This dataset was developed to map changes in greater sage-grouse range over time in northeastern California. Records in this dataset represent current and historic range. Current and historic range were mapped and reported on by Frank Hall in Determining Changes in Abundance of Sage-Grouse (Centrocercus urophasianus) in California, August 1995. The ranges were hand drawn on 1:250,000 scale USGS maps and then digitized in ArcInfo. For a larger range mapping project and range continuity, input from DFG and BLM wildlife biologists in northern California, southern Oregon, and western Nevada was collected using the same methods; hand drawn ranges on 1:250,000 scale USGS maps and then digitized in ArcInfo. In 2005, Hall modified the current range that is represented in this dataset. Number of records: There are 9 polygons representing current or historic range. Geographic extent of records: Extent includes Siskiyou, Modoc, Lassen, Sierra, Plumas, and Shasta Counties in California.
Operational Division Boundaries - OSPR [ds355]

The shoreline operational divisions are organized and named according to County boundaries. Within county domains, divisions are boundaries guided by logical geopolitical features such as coastal physical characteristics and land ownership/ management issues, shoreline cleanup logistical considerations, and manageable sized coastline segments (generally not longer than about ten miles although some variation occurs.) Logistics, access, and manageability were driving considerations in this effort, particularly as it relates to types of cleanup operations required and problems likely to be present.
Sensitive Sites - OSPR [ds358]

The data was created by reviewing the information contained in the Site Summaries. If the Site Summary contained a latitude/longitude of the location, the ArcView Geotools extension was used to create the point shp file. If the coordinate was not know, the tool was used to identify the coordinate by selecting the location from a georeferenced USGS quad map. The extents were identified from the Site Summary and each extents was copied from the 24K Coast shp file or from the Delta Shp file. The Xtools extension was used to cut and copy each segment to the extents shp file.

Acorns - Spears and Didion Ranches [ds322]

These data are the characteristics and acorn counts from 2005 of individual live oak trees found in 0.05-ha circular habitat plots at Spears and Didion Ranches, Placer County, California. Acorns were counted over a 30-second period at each tree using binoculars. Each count involved two 15-second periods, one counting a lower section of a tree and one counting an upper section. Counts were done in mid-September 2005. Trees were tagged with individually numbered 2" diameter aluminum tree tags at 4.5 ft above the ground with the tags facing towards the center of the 0.05-ha sampling plot. There were three 0.05-ha circular habitat sampling plots at each of the 15 sample points, and there were 2-4 oaks per vegetation plot.
Aspen Characteristics - El Dorado National Forest [ds363]

The database represents aspen stand locations and field assessments conducted in the Eldorado National Forest, Eldorado and Amador Counties, California. Data was gathered during the summers of 1999-2001. Assessments were conducted primarily by volunteers for the USDA Forest Service. Assessments were conducted within known aspen stands in the region, or stands identified during field surveys. The survey method was not intended to capture all known aspen sites in this region, and so this data does not represent a comprehensive map of aspen stands in the region. Aspen stands were assessed using a protocol developed by the Eldorado National Forest. Basic Information gathered included location and vegetative characteristics, and if browsing of the aspen was present or absent.
