These data facilitate the planning and management for biological diversity on a regional and national scale. Small Grains - Areas used for the production of graminoid crops such as wheat, barley, oats, and rice. It has many advantages including: • Multiple data sources • No limit of the amount of data you can download (no max point limit) There are many different resolutions of surface information in the National Elevation Dataset (NED). Second stage sampling is accomplished by selecting SSUs (pixels) within each PSU (NAPP photograph) to provide the actual locations for the reference land cover classification. 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. 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. Data themes included are Boundaries, Geographic Names, Transportation, Contours, Hydrography, Land Cover, Shaded Relief, and Bathymetry. Originator: Multi-Resolution Land Characteristics (MRLC) Consortium - USGS, EPA, NOAA, BLM, NASA, NPS, USDA-NASS, USFWS, US Army COE. 9. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. Similar problems exist within agricultural classes due to crop rotations. Land Cover 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. 5. Units are percent. << Back to Land Cover Data Overview: Data and Tools. The USGS, working in partnership with the Federal interagency Multi-Resolution Land Characteristics (MRLC) Consortium, is developing the National Land Cover Database (NLCD) 2016. The class numbers shown below represent the original digital values of the classes in the NLCD data set. The goal of the GAP/LANDFIRE National Terrestrial Ecosystems 2011 data is to provide accurate, seamless data on the vegetation and land cover of the United States. More information about the NLCD can be found at URL: . Details. Population densities will be lower than in high intensity residential areas. Figure 1. National Land Cover Database 2011 (NLCD 2011) is the most recent national land cover product created by the Multi-Resolution Land Characteristics (MRLC) Consortium. Published Dec 02, 2020. The same is true for the land use related differences between the quarry/strip mine class and the sandy/gravel class. The USGS National Land Cover Database (NLCD) is also available and it provides information about general land cover types with 16 land cover classes (for example, Low Intensity Developed, Deciduous Forest). Distribution_Information: Resource_Description: Downloadable Data. The GAP/LANDFIRE National Terrestrial Ecosystems data layer provides detailed information about the vegetation of the United States. 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. 1) Some of the TM data sets are not temporally ideal. Selected scenes were geometrically and radiometrically corrected, then combined into s… Emergent Herbaceous Wetlands - Areas where perennial herbaceous vegetation accounts for 75 to 100 percent of the cover and the soil or substrate is periodically saturated with or covered with water. 16.

The application also included buttons to display two reference data sets in the background: (1) a point coverage of all of the original labels in the GIRAS files (unmodified by GIS polygon processing operations), and (2) the 1992 National Land Cover Data Set (Vogelmann and others, 2001; U.S. Geological Survey, 2002). NLCD2006 is based primarily on the unsupervised classification of Landsat Enhanced Thematic Mapper+ (ETM+) circa 2006 satellite data. 2002) as well as land use classes described in the National Land Cover Dataset 2001 (Homer et al. Published Dec 02, 2020. Examples include parks, lawns, golf courses, airport grasses, and industrial site grasses. The GAP/LANDFIRE National Terrestrial Ecosystems data set includes detailed vegetation and land cover patterns for the continental United States. Likewise, there was often disagreement between LUDA and the Gap Analylsis Program on these classes. Access & Use Information ... Creative Commons Attribution. February 2012. 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). 2007). Download Land Cover Data. The National Land Cover Dataset (NLCD) is a component of the USGS Land Cover Characterization Program. , . National Land Cover Data Set NLCD, U.S. Geological Survey (USGS) The NLCD was compiled from Landsat TM imagery (circa 1992) with a spatial resolution of 30 meters supplemented by various ancillary data (where available). Vogelmann, J.E., Sohl, T., Campbell, P.V., and Shaw, D.M., 1998, Regional land cover characterization using landsat thematic mapper data and ancillary data sources: Environmental Monitoring and Assessment, v. 51, pp. Furthermore, the accuracy assessments correspond to "federal regions", which are groupings of contiguous states. Examples include apartment complexes and row houses. 3. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. MODIS/Terra and Aqua Land Cover Dynamics Yearly L3 Global 500 m SIN Grid V006 – MCD12Q2. Additional products include percent developed impervious, percent tree canopy, and land cover change. The National Land Cover Database products are created through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. Another source of error is the discrepancy between satellite imagery and NAPP photograph acquisition time. Digital land cover and terrain data of the Arctic National Wildlife Refuge (ANWR) were prduced by the U.S. Geological Survey (USGS) Earth Resources Observation Systems Field Office, Anchorage, Alaska for the U.S. Thus, the reliability of the data is greatest at the state or multi-state level. The United States Geological Survey (USGS) just released in May 2019 an update to the National Land Cover Database (NLCD), which details land cover change for the lower 48 states.The results show significant change to the lower 48 since 2001. 2001 National Land Cover Data Set Positives of the USGS 2001 National Land Cover Data Set Open Water - areas of open water, generally with less than 25 percent or greater cover of water (per pixel). Metadata_Reference_Information: Metadata_Date: 20070208 The Digital Object Identifier (DOI) for the data product is given below. 4) spatial uncertainty, such as geo-registration error. The framework of a national land use and land cover classification system is presented for use with remote sensor data. 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. West Africa land use and land cover time series (USGS Fact Sheet 2017-3004) Started in 1999, the West Africa Land Use Dynamics project represents an effort to map land use and land cover, characterize the trends in time and space, and understand their effects on the environment across West Africa. When hay and pasture areas are non-green, those areas not easily distinguishable from other agricultural areas using remotely sensed data. 2) time difference in source imagery and reference data acquisition (hay/pasture, row crop, wetland, transitional), Vegetation accounts for less than 20 percent of the cover. 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. The GAP/LANDFIRE National Terrestrial Ecosystems data layer provides detailed information about the vegetation of the United States. 1, p. 45-57. The map legend includes types described by NatureServe's Ecological Systems Classification (Comer et al. Low Intensity Residential - Includes areas with a mixture of constructed materials and vegetation. Urban or Recreational Grasses - Vegetation (primarily grasses) planted in developed settings for recreation, erosion control, or aesthetic purposes. LAND_COVER_CHANGE_2001_2006_USGS_IN is a grid (30-meter cell size) showing 2001 to 2006 Land Cover Change pixels in Indiana. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. 4) Separation of natural grass and shrub is problematic. This table can be related using the attribute "VALUE". 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. The statistical accuracy of the data is known only for the region. National Land Cover Database 2011 (NLCD 2011) is the most recent national land cover product created by the Multi-Resolution Land Characteristics (MRLC) Consortium. 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. Acquisition dates of the NAPP photographs range from the late 1980s to 1997, whereas the satellite data were mostly acquired from 1991 to 1993. This grid is a subset of the National Land Cover Database (NLCD 2006) suite of data products.

Projected data include three time periods (2020s, 2050s, and 2080s) and two climate scenarios (Representative Concentration Pathways [RCP] 4.5 and … Evergreen Forest - Areas characterized by trees where 75 percent or more of the tree species maintain leaves all year. 11. The land cover values were reclassified and numbered 1 to 20. While this is not viewed as a major problem for most classes, it is possible that some land cover features change more rapidly than might be expected (for example, hay one year, row crop the next). 18. 7. National Biogeographic Map. The VIIRS Land Cover Dynamics product suite provides global land surface phenology metrics for up to two detected growing cycles per year. The USGS, in collaboration with the Bureau of Land Management, has produced projected rangeland fractional cover products for Western U.S. 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. Note: download the data files labeled "grid_cell". Constructed materials account for 30 to 80 percent of the cover. 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. Projected NLCD Rangeland Cover Products Through 2080 – Now Available. The analysis and interpretation of the satellite imagery was conducted using very large, sometimes multi-state image mosaics (up to 18 Landsat scenes). U.S. Geological Survey Fact Sheet 2012–3020. Transitional - Areas of sparse vegetative cover (less than 25 percent that are dynamically changing from one land cover to another, often because of land use activities. Fish and Wildlife Service (USFWS). 12. 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. 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. Learn more about NLCD 2011 >> Why are these data important? Using a relatively small number of aerial photographs for "ground truth", the thematic interpretations were necessarily conducted from a spatially broad perspective. Bare Rock, Sand, or Clay - Perennially barren areas of bedrock, desert, pavement, scarps, talus, slides, volcanic material, glacial debris, and other accumulations of earthen material. Examples include forest clearcuts, a transition phase between forest and agricultural land, the temporary clearing of vegetation, and changes due to natural causes (such as fire or flood). Any changes that took place across the landscape over this time period complicate interpretation and comparison between reference and mapped land cover. 415-428. 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. Additional information about the National Land Cover Dataset (NLCD) can found at URL: . Projected NLCD Rangeland Cover Products Through 2080 – Now Available. Access to land cover resources including a Factsheet and information about other land cover mapping efforts. Title: 2011 National Land Cover Data Set (NLCD) . This grid is a subset of the National Land Cover Data (NLCD 2011) data set. The spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classification system. PSUs are selected from a sampling grid based on NAPP flight lines and photograph centers, each grid cell measures 15' x 15' (minutes of latitude and longitude) and consists of 32 photographs from the National High Altitude Program (NHAP). 10. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. Shrub cover may be less than 25 percent in cases when the cover of other herbaceous or tree cover is less than 25 percent. The map legend based on NatureServe’s ecological system classification scheme provides detailed information on the vegetation types at a plant community level. Detailed Description. These data can be used in a geographic information system (GIS) for many purposes such as assessing wildlife habitat, water quality, pesticide runoff, and land use change. The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. 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. An example of mapping error is the limited success in discriminating hay/pasture from row crops using leaf-off season (spring or fall) Landsat TM data. 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 LAND_COVER_2006_USGS_IN is a grid (30-meter cell size) showing 2006 Land Cover data in Indiana.

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. Low accuracy for classes related to land use is understandable. The USGS, in collaboration with the Bureau of Land Management, has produced projected rangeland fractional cover products for Western U.S. Database (NLCD) land cover layer is one of several primary and supplementary layers in NLCD 2006. 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 spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classifi... Land Cover Data Download, Metadata, and Web Services. 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 data analyst assumes that there is a temporal window during which hay and pasture green up before most other annual or perennial vegetation. “National Land Cover Database 2011 (NLCD 2011) is the most recent national land cover product created by the Multi-Resolution Land Characteristics (MRLC) Consortium. 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. 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. 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. 1:250,000-scale, US land use data. The goal of the GAP/LANDFIRE National Terrestrial Ecosystems 2011 data is to provide accurate, seamless data on the vegetation and land cover of the United States. The Natural Terrestrial Ecosystems Viewer allows the user to explore the land cover data for the conterminous United States. The 2012 dataset is based on a slightly modified version of the National Land Cover Database 2011 (NLCD 2011) that was recoded to a schema of land uses, and mapped back in time to develop datasets for the four earlier eras. 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. 3) Wetlands classes are extremely difficult to extract from Landsat TM spectral information alone. Visually checked against land use and land cover data sets. The U.S. Geological Survey (USGS), in partnership with several federal agencies, has developed and released four National Land Cover Database (NLCD) products over the past two decades: NLCD 1992, 2001, 2006, and 2011.
