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. Map Name: Layers Legend All Layers and Tables Dynamic Legend Dynamic All Layers Layers: USGS 2006 National Landcover Metadata Updated: February 27, 2019 The National Land Cover Database products are created through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. 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). Published Dec 02, 2020. Another source of error is the discrepancy between satellite imagery and NAPP photograph acquisition time. Mixed Forest - Areas dominated by trees where neither deciduous nor evergreen species represent more than 75 percent of the cover present. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. 1995 Land Cover/Use (LTRM) 1994 Land Cover/Use (LTRM) 1991 Land Cover/Use (LTRM) 1989 Landsat Satellite Land Cover/Use (LTRM) 1989 Land Cover/Use (LTRM) 1975 Land Cover/Use (GREAT) 1890's Land Cover/Use (Mississippi River Commission) Vegetation (LTRM monitoring data) Floodplain Forests (LTRM) LTRM Land Cover Viewer ; Land Cover/Use Interactive Maps The map legend based on NatureServe’s ecological system classification scheme provides detailed information on the vegetation types at a plant community level. 1:250,000-scale, US land use data. 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. Major factors that have contributed to disagreements between mapped land cover and reference land cover labels include: 1) Landsat TM data quality and mapping error, The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. 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 … 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. Projected NLCD Rangeland Cover Products Through 2080 – Now Available. The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. Additional products include percent developed impervious, percent tree canopy, and land cover change. The use of ancillary information such as National Wetlands Inventory data is highly desirable. Unlike LULC, which originated as a vector data set in which the smallest features are about ten acres in size, NLCD is a raster data set with a spatial resolution of 30 meters (i.e., pixels represent about 900 square meters on the ground) derived from Landsat TM imagery. A screen shot of the National Land Cover Dataset from 2001. 2001 National Land Cover Data Set 10. Vegetation accounts for less than 20 percent of the cover. The National Land Cover Dataset (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. It is difficult to acquire a single-date of imagery (leaves-on or leaves-off) that adequately differentiates between both deciduous and hay/pasture and hay/pasture and row crops. 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.
