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. Grasslands or Herbaceous - Areas dominated by upland grasses and forbs. The data in NLCD 2011 are completely integrated with NLCD 2001 (2011 Edition) and NLCD 2006 (2011 Edition). Low accuracy for classes related to land use is understandable. Image Dimensions: 720 x 474 Projected NLCD Rangeland Cover Products Through 2080 – Now Available. 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. This grid is a subset of the National Land Cover Database (NLCD 2006) suite of data products. Visually checked against land use and land cover data sets. This table can be related using the attribute "VALUE". You need to enable JavaScript to run this app. 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. For more information, visit the National Land Cover Database website.. Examples include apartment complexes and row houses. Any changes that took place across the landscape over this time period complicate interpretation and comparison between reference and mapped land cover. Download Land Cover Data. The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. The National Land Cover Dataset (NLCD) is a component of the USGS Land Cover Characterization Program. Access & Use Information ... Creative Commons Attribution. 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). USGS 2001 National Landcover - Download Data data 71 views Download data Link is ok Openness score. More information about the NLCD can be found at URL: . These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. NLCD 2006 is the most recent 30-meter, seamless, wall-to-wall land cover database for the conterminous United States. Visit page . Vegetation may account for 20 to 70 percent of the cover. Overview EROS is central to the creation of the National Land Cover Database (NLCD), which is updated every five years and stands as the definitive land cover database for the United States. Deciduous Forest - Areas dominated by trees where 75 percent or more of the tree species shed foliage simultaneously in response to seasonal change. The data analyst assumes that there is a temporal window during which hay and pasture green up before most other annual or perennial vegetation. 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. 2002) as well as land use classes described in the National Land Cover Dataset 2001 (Homer et al. The GAP/LANDFIRE National Terrestrial Ecosystems data layer provides detailed information about the vegetation of the United States. NASA EOSDIS Land Processes DAAC. The USGS, working in partnership with the Federal interagency Multi-Resolution Land Characteristics (MRLC) Consortium, is developing the National Land Cover Database (NLCD) 2016. 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. The class numbers shown below represent the original digital values of the classes in the NLCD data set. 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). These areas most commonly include single-family housing units. 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. 2) time difference in source imagery and reference data acquisition (hay/pasture, row crop, wetland, transitional), 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. LAND_COVER_2011_USGS_IN is a grid (30-meter cell size) showing 2011 Land Cover data in Indiana. Small Grains - Areas used for the production of graminoid crops such as wheat, barley, oats, and rice. The National Land Cover Database. 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). However, if leaf-off data acquisition is not temporally ideal (e.g., the greenness level of hay/pasture areas is low), it may result in misclassification between hay/pasture and other agricultural lands. , . 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. 9. 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. Metadata_Reference_Information: Metadata_Date: 20070208 The VIIRS Land Cover Dynamics product suite provides global land surface phenology metrics for up to two detected growing cycles per year. Woody Wetlands - Areas where forest or shrubland vegetation accounts for 25 to 100 percent of the cover and the soil or substrate is periodically saturated with or covered with water. National Land Cover Database 2011 (NLCD 2011) is the most recent national land cover product created by the Multi-Resolution Land Characteristics (MRLC) Consortium. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. 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. Use 7zip or another compression program to open these files. MCD12Q2 MODIS/Terra+Aqua Land Cover Dynamics Yearly L3 Global 500m SIN Grid V006 [Data set]. Canopy is never without green foliage. Pasture or Hay - Areas of grasses, legumes, or grass-legume mixtures planted for livestock grazing or the production of seed or hay crops. An alternative is USGS data from the National Map Viewer. 2007). In rare cases, herbaceous cover is less than 25 percent, but exceeds the combined cover of the woody species present. The Land Cover Data - Version 1.0 represents a highly thematically detailed land cover map of the U.S. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. USGS 2001 National ... land-cover; land-use; usgs; Additional Metadata. Published Dec 02, 2020. Constructed materials account for 80 to 100 percent of the cover. The same is true for the land use related differences between the quarry/strip mine class and the sandy/gravel class. 12. 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. 10. The GAP/LANDFIRE National Terrestrial Ecosystems data layer provides detailed information about the vegetation of the United States. Urban or Recreational Grasses - Vegetation (primarily grasses) planted in developed settings for recreation, erosion control, or aesthetic purposes. MODIS/Terra and Aqua Land Cover Dynamics Yearly L3 Global 500 m SIN Grid V006 – MCD12Q2. 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. Visually checked against land use and land cover data sets. 8. Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, GAP/LANDFIRE National Terrestrial Ecosystems 2011 Data, Metadata. Population densities will be lower than in high intensity residential areas. Shrubland - Areas dominated by shrubs; shrub canopy accounts for 25 to 100 percent of land cover. The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. 18. LAND_COVER_CHANGE_2001_2006_USGS_IN is a grid (30-meter cell size) showing 2001 to 2006 Land Cover Change pixels in Indiana. Detailed Description. The map legend includes types described by NatureServe's Ecological Systems Classification (Comer et al. Fish and Wildlife Service (USFWS). Data themes included are Boundaries, Geographic Names, Transportation, Contours, Hydrography, Land Cover, Shaded Relief, and Bathymetry. Using a relatively small number of aerial photographs for "ground truth", the thematic interpretations were necessarily conducted from a spatially broad perspective. 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 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. When hay and pasture areas are non-green, those areas not easily distinguishable from other agricultural areas using remotely sensed data. 16.
