(Read More), NLCD tree canopy cover is a 30 m raster geospatial dataset that is available for the conterminous United States, coastal Alaska, Hawaii, and Puerto Rico. This dataset has one image for the continental US for each epoch. For additional information, please refer to the README file, license file, or other information delivered along with the image product. Ecological Potential rangeland fractional cover data products represent the potential cover given the most productive, least disturbed, portion of the 1985-2020 Landsat archive. database spanning 8 epochs The change index was designed to assist NLCD users to understand complex land cover change with a single product. These data contain percent tree canopy estimates, as a continuous variable, for each pixel across all land covers and types and are generated by the United States Forest Service (USFS). A main objective of releasing these maps is to provide a tool for better monitoring EAG dynamics and informing conservation and management efforts at local to regional scales.

Pixels derived from the 2019 Oil and Natural Gas Wells NLCD products are created by the Multi-Resolution Land Characteristics (MRLC) Consortium, a partnership of Federal agencies led by the U.S. Geological Survey. 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. NLCD 2019 represents the latest evolution of NLCD land cover products focused on providing innovative land cover and land cover change data for the Nation. This collaboration provides a first of its kind rangeland monitoring framework with multiple yearly fractional components spanning 1985 to 2017. The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. 2.0, June 2021): U.S. Geological Survey data release, User feedback on the data is encouraged.

Masked areas meet three criteria: 1) they are within the sagebrush biome (Jeffries and Finn 2019), 2) within the following EPA level 3 ecoregions: Arizona/New Mexico Mountains, Arizona/New Mexico Plateau (excluding the San Luis Valley from the mask), Colorado Plateaus (excluding the Uinta Basin from the mask), Mojave Basin and Range, and Sonoran Basin and Range, and 3) have a maximum of 0% sagebrush cover observed over the 1985-2020 RCMAP time-series. https://doi.org/10.1016/j.isprsjprs.2020.02.019. The NLCD Land Cover change index combines information from all years of land cover change and provides a simple and comprehensive way to visualize change from all 8 dates of land cover in a single layer. The latest evolution of NLCD products are designed for widespread application in biology, climate, education, land management, hydrology, environmental planning, risk and disease analysis, telecommunications and visualization. Two file types are available: individual dates that supply a wall-to-wall map, and change files that compare one date to another. 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. The images rely on the imperviousness data layer for the urban classes and on a decision-tree classification for the rest. C-CAP data forms the coastal expression of the National Land Cover Database (NLCD) and the A-16 land cover theme of the National Spatial Data Infrastructure. NLCD 2019offers land cover for years 2001, 2003, 2006, 2008, 2011, 2013, 2016, 2019, as well as impervious surface and impervious descriptor layers for each epoch. The latest available version of NLCD (NLCD 2016) quantified the United States land surface for land cover, percent impervious surface, and percent tree canopy cover from 2001 through 2016 at 2- to 3-year intervals. and have been removed from the landcover but remain as part of NLCD 1992, NLCD 2001, NLCD 2006, and NLCD 2011 are National Land Cover Database classification schemes based primarily on Landsat data along with ancillary data sources, such as topography, census and agricultural statistics, soil characteristics, wetlands, and other land cover maps.

These products have been produced by USGS in collaboration with the Bureau of Land Management. Given the importance of evaluating global land cover data for producers and potential users, the 2010 MODIS v5.1 LCT product IGBP (International Geosphere-Biosphere Programme) layer was evaluated based on two grid maps at scales of 100-m and 500-m,which were derived by rasterizing the 2010 data from the national land use/cover database of China . Component cover were harmonized so that the sum of bare ground, shrub, herbaceous, and litter cover adds to ~100% and secondary components sagebrush and annual herbaceous cover were harmonized to their respective primary components of shrub and herbaceous cover, (so their cover could not be greater than their primary component). The .gov means its official. Impervious surfaces account for 20% to 49% percent of total cover. Most U.S. Geological Survey (USGS) information is federally created data and Production includes ingesting partner data from 10 different Government partners and Federal agencies that are used to improve accuracy and ensure a cohesive product across these partners. Dwarf scrub: Alaska only areas dominated by shrubs less than 20 centimeters tall with shrub canopy typically greater than 20% of total vegetation. The use of standardized data and procedures assures consistency through time and across geographies. Find information on spaces, staff, and services. Lichens: Alaska only areas dominated by fruticose or foliose lichens generally greater than 80% of total vegetation. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (for example, urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. The National Land Cover Database (NLCD) provides nation-wide data on land cover and land cover change at the Landsat Thematic Mapper (TM) 30-meter resolution. For any dataset, the specific construction of the correct citation information can be found on the DOI Landing page for each individual product and can be accessed below: For further details and information on the proper citation and acknowledgment of LP DAAC products, please refer to Citing Our Data. The National Land Cover Database (NLCD) provides nation-wide data on land cover and land cover change at the Landsat Thematic Mapper (TM) 30-meter resolution. These areas most commonly include large-lot single-family housing units, parks, golf courses, and vegetation planted in developed settings for recreation, erosion control, or aesthetic purposes. Remote sensing provides a cost-effective and reliable method for monitoring change through time and attributing changes to drivers. To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nations land resources, the USGS has designed a new generation of NLCD products named NLCD 2019. By comparison, overall accuracies at Level II and Level I for the NLCD 1992 were 58% and 80%.
