The USGS, in collaboration with the Bureau of Land Management, has produced projected rangeland fractional cover products for Western U.S. 3. However, there is a temporal window during which hay and pasture areas green up before most other vegetation (excluding evergreens, which have different spectral properties); during this window these areas are easily distinguishable from other crop areas. The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. 2) The data sets used cover a range of years (see data sources), so changes that have occurred across the landscape over the time period may not have been captured. 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. Projected NLCD Rangeland Cover Products Through 2080 – Now Available. Despite the extensive use of ancillary data, such as the census data, it is very difficult to unambiguously separate high intensity residential from other urban uses, either during the mapping or photo-interpretation process. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. 14. Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, GAP/LANDFIRE National Terrestrial Ecosystems 2011 Data, Metadata.

NLCD 2011 is the most up-to-date iteration of the National Land Cover Database, the definitive Landsat-based, 30-meter resolution land cover database for the Nation. U.S. Geological Survey Fact Sheet 2012–3020. The data analyst assumes that there is a temporal window during which hay and pasture green up before most other annual or perennial vegetation. Low accuracy for classes related to land use is understandable. , . 1. This grid is a subset of the National Land Cover Database (NLCD 2006) suite of data products. Low Intensity Residential - Includes areas with a mixture of constructed materials and vegetation. Metadata_Reference_Information: Metadata_Date: 20070208 Much emphasis was put on GAP, LUDA, or proximity to streams and rivers as well as spectral data to delineate wetlands in areas without NWI data. The primary source data were bands 3, 4, 5, and 7 (visible red, near-infrared, mid-infrared, and thermal infrared) of cloud-free Landsat TM scenes acquired during the spring and fall (when trees are mostly bare of leaves) of 1992. LAND_COVER_2011_USGS_IN is a grid (30-meter cell size) showing 2011 Land Cover data in Indiana. The U.S. Geological Survey (USGS) has released a new generation of National Land Cover Database (NLCD) products named NLCD 2016 for the conterminous U.S. NLCD 2016 contains 28 different land cover products characterizing land cover and land cover change across 7 epochs from 2001-2016, urban imperviousness and urban imperviousness change across 4 epochs from 2001 … A geographically stratified random sampling is performed with one photograph from the National Aerial Photography Program photo being randomly selected from each cell (geographic strata), if a sampled photograph falls outside of the regional boundary it is not used. 4) spatial uncertainty, such as geo-registration error. The USGS 2001 National Land Cover Data Set is the latest, most accurate, nearest-to-complete and standardized land use coverage for the entire United States. Projected data include three time periods (2020s, 2050s, and 2080s) and two climate scenarios (Representative Concentration Pathways [RCP] 4.5 and … This dataset provides a U.S. national 60-meter, 19-class mapping of anthropogenic land uses for five time periods: 1974, 1982, 1992, 2002, and 2012. The NLCD was produced as a cooperative effort between the U.S. Geological Survey (USGS) and the U.S. Environmental Protection Agency (US EPA) to produce a consistent, land cover data layer for the conterminous U.S. using early 1990s Landsat thematic mapper (TM) data purchased by the Multi-resolution Land Characterization (MRLC) Consortium. The GAP/LANDFIRE National Terrestrial Ecosystems data layer provides detailed information about the vegetation of the United States. Vegetation may account for 20 to 70 percent of the cover. Similar problems exist within agricultural classes due to crop rotations. One class that suffers most is the transitional barren, a class that is designed for conditions such as temporary clearing and regeneration of forest cover. Visually checked against land use and land cover data sets. February 2012. 5. The raster spatial layer was projected and land cover information was selected using the 8-digit hydrologic unit code (HUC8) and the ARC/INFO GRIDCLIP command. Conterminous United States (based on 2011 imagery) Download Alaska Land Cover * Download Hawaii Land Cover * Download Puerto Rico Land Cover * * These data are based on 2001 imagery. Thus, the reliability of the data is greatest at the state or multi-state level. Other GAP Online Data Viewers are also highlighted. The Land Cover Data - Version 1.0 represents a highly thematically detailed land cover map of the U.S. NLCD (the National Land Cover Database) is a 30-m Landsat-based land cover database spanning 8 epochs (1992, 2001, 2004, 2006, 2008, 2011, 2013 and 2016). The framework of a national land use and land cover classification system is presented for use with remote sensor data. The analysis and interpretation of the satellite imagery was conducted using very large, sometimes multi-state image mosaics (up to 18 Landsat scenes). •USGS/EPA National Land Cover Dataset (NLCD) •DOI/USDA LANDFIRE Program •Western States Consumptive Water Use •NOAA Coastal Change Analysis Program •Global Forest Watch Forest Change Products Landsat is the most widely used land remote sensing data source within Federal civil agencies Commercial, Industrial, or Transportation - Includes infrastructure (roads, railroads) and all highways and all developed areas not classified as High Intensity Residential. 2002) as well as land use classes described in the National Land Cover Dataset 2001 (Homer et al. NLCD (the National Land Cover Database) is a 30-m Landsat-based land cover database spanning 8 epochs (1992, 2001, 2004, 2006, 2008, 2011, 2013 and 2016). 1992 data are primarily based on unsupervised classification of Landsat data, while the rest of the images rely on the imperviousness data layer for the urban classes and on a decision-tree classification for the rest. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. The same is true for the land use related differences between the quarry/strip mine class and the sandy/gravel class. 415-428. National Land Cover Database 2006 (NLCD2006) is a 16-class land cover classification scheme that has been applied consistently across the conterminous United States at a spatial resolution of 30 meters. 12. 8. The discrimination between hay and pasture and deciduous forest is likewise optimized by selecting data in a temporal window where deciduous vegetation has yet to leaf out. “National Land Cover Database 2011 (NLCD 2011) is the most recent national land cover product created by the Multi-Resolution Land Characteristics (MRLC) Consortium. Mixed Forest - Areas dominated by trees where neither deciduous nor evergreen species represent more than 75 percent of the cover present. The National Land Cover . Open Water - areas of open water, generally with less than 25 percent or greater cover of water (per pixel). Vogelmann, J.E., Sohl, T., and Howard, S.M., 1998, Regional characterization of land cover using multiple sources of data: Photogrammetric Engineering and Remote Sensing, v. 64, no. Vegetation accounts for less than 20 percent of the cover. Downloads & Resources. This raster spatial layer contains land cover information from the 1992 National Land Cover Dataset (NLCD) and was constructed to show land cover and land use in the upper Washita River basin in southwestern Oklahoma. The class numbers shown below represent the original digital values of the classes in the NLCD data set. Units are percent. 20. The use of ancillary information such as National Wetlands Inventory data is highly desirable. The SSUs are manually interpreted and misclassification errors are estimated and described using a traditional error matrix as well as a number of other important measures including the overall proportion of pixels correctly classified, user's and producer's accuracies, and omission and commission error probabilities. The map legend includes types described by NatureServe's Ecological Systems Classification (Comer et al. The NLCD was produced as a cooperative effort between the U.S. Geological Survey (USGS) and the U.S. Environmental Protection Agency (US EPA) to produce a consistent, land cover data layer for the conterminous U.S. using early 1990s Landsat thematic mapper (TM) data purchased by the Multi-resolution Land Characterization (MRLC) Consortium.
