An official website of the United States government. USGS is currently working in partnership with the Interagency Multi-Resolution Land Characteristics (MRLC) Consortium to produce the next version of the National Land Cover Database, NLCD 2019. The Land Cover Database (LCDB), available to users of the Land Resource Information System (LRIS) portal offers environment data held by Landcare Research for re-use in GIS and other applications that can handle geospatial data for mapping, querying and spatial analyses. Moss: Alaska only areas dominated by mosses, generally greater than 80% of total vegetation. These areas are not subject to intensive management such as tilling, but can be utilized for grazing. 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 . The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. Through July 2020, Landsat ARD composites have been generated and all land cover, land cover change, and impervious procedures, models, and documentation have been completed. 2.0, June 2021): U.S. Geological Survey data release, https://doi.org/10.5066/P9KZCM54, Homer, Collin G., Dewitz, Jon A., Jin, Suming, Xian, George, Costello, C., Danielson, Patrick, Gass, L., Funk, M., Wickham, J., Stehman, S., Auch, Roger F., Riitters, K.

In this episode, we learn about the latest land cover release from EROS. 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 2011 provides - for the first time - the capability to assess wall-to-wall, spatially explicit, national land cover changes and trends across the United States from 2001 to 2011. NLCD 2019 updates all previously released versions of impervious products for CONUS and provides integrated analysis for all Land Cover dates. 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. Accuracy assessment of NLCD 2006 focused on four primary products: 2001 land cover, 2006 land cover, land-cover change between 2001 and 2006, and impervious surface change between 2001 and 2006. Percent of the pixel covered by developed impervious surface. 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.

Trend analysis for each component is also available as a zip file for the full 1985-2021 period to help users understand the magnitude of change. 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 23-year intervals. NLCD supports a wide variety of Federal, State, local, and nongovernmental applications that seek to assess ecosystem status and health, understand the spatial patterns of biodiversity, predict effects of climate change, and develop land management policy. Dewitz, J., and U.S. Geological Survey, 2021, National Land Cover Database (NLCD) Microsoft buildings. 2001, ca. Two file types are available: individual dates that supply a wall-to-wall map, and change files that compare one date to another. Additional Information Basics Pixels derived from the Microsoft US Building NLCD 2019 also includes a wind energy layer across all impervious products. ), The need to monitor change in sagebrush steppe is urgent due to the increasing impacts of climate change, shifting fire regimes, and management practices on ecosystem health. NLCD also ingests an increasing number of ancillary data like building footprints, well pads, wind turbine footprints, and other data to increase the accuracy of its impervious products. Mixed forest: areas dominated by trees generally greater than 5 meters tall, and greater than 20% of total vegetation cover. This descriptor layer identifies types of roads, wind tower sites, building locations, and energy production sites to allow a deeper analysis of developed features. Grassland/herbaceous: areas dominated by gramanoid or herbaceous vegetation, generally greater than 80% of total vegetation. Specific examples of LP DAAC datasets would include: The appropriate citation of NASAs LP DAAC datasets are product-specific and should follow the Digital Object Identifier (DOI) string standard. NLCD supports a wide variety of Federal, State, local, and nongovernmental applications that seek to assess ecosystem status and health, understand the spatial patterns of biodiversity, predict effects of climate change, and develop land management policy.
