Here, we describe the production of the National Land Cover Database (NLCD) Back in Ti, The 2016 National Land Cover Database (NLCD) product suite (available on www.mrlc.gov), includes Landsat-based, 30 m resolution products over the conterminous (CONUS) United States (U.S.) for land cover, urban imperviousness, and tree, shrub, herbaceous and bare ground fractional percentages. The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at 30-meter resolution. Featured Resources. Non-road non-energy impervious. A .gov website belongs to an official government organization in the These areas most commonly include large-lot single-family housing units, parks, golf courses, and vegetation planted in developed settings for recreation, erosion control, or aesthetic purposes. These areas are not subject to intensive management such as tilling, but can be utilized for grazing. In this episode, we hear how Landsat helps monitor vulnerable rangelands in the Western U.S. The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely. Chicago. By comparison, overall accuracies at Level II and Level I for the NLCD 1992 were 58% and 80%. 2.0, June 2021): U.S. Geological Survey data release, Land cover is a key environmental variable, underpinning widespread environmental research and decision-making. In this episode, we talk about the National Land Cover Database. Areas previously identified as well pads NLCD also includes anNLCD Land Cover Change Index. 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. An official website of the United States government. Source is available. The two main objectives were assessment of agreement between map and reference labels for the three, single-date NLCD land cover products at Level II and Level I, Release of NLCD 2006 provides the first wall-to-wall land-cover change database for the conterminous United States from Landsat Thematic Mapper (TM) data. The 2016 release saw landcover created for additional years of 2003, 2008, and 2013. Cheatgrass (Bromus tectorum) is a dominant species, but this dataset also includes Bromus arvensis L., Bromus briziformisFisch. Use the interface below to filter and download available NLCD products. These products update all previously released versions of landcover and impervious products for CONUS (NLCD 2001, NLCD 2006, NLCD 2011, NLCD 2016) and are not directly comparable to previous products. 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. A main objective of releasing these maps is to provide a tool for better monitoring EAG dynamics and informing conservation and management efforts at local to regional scales. (Read More), NLCD imperviousness products represent urban impervious surfaces as a percentage of developed surface over every 30-meter pixel in the United States. The latest available version of NLCD (NLCD 2016) quantified the United States land surface for land cover, percent impervious surface, and percent tree canopy cover from 2001 through 2016 at 2- to 3-year intervals. NLCD's impervious surface descriptor product identifies types of roads, core urban areas, and energy production sites for each impervious pixel to allow deeper analysis of developed features. residential/commercial/industrial areas, parks, and golf courses. For any dataset, the specific construction of the correct citation information can be found on the DOI Landing page for each individual product and can be accessed below: For further details and information on the proper citation and acknowledgment of LP DAAC products, please refer to Citing Our Data. Specific examples of non-USGS imagery or data products include: Users may still acknowledge or cite any non-USGS dataset according to the format listed under USGS Products with some modification.

NavStreets Street Data. The National Land Cover Database (NLCD) provides nation-wide data on land cover and land cover change at the Landsat Thematic Mapper (TM) 30-meter resolution. The mapping and modeling process results in a temporally consistent and spatially coherent land cover and land cover trajectory throughout the NLCD time span (2001 through 2019). Crop vegetation accounts for greater than 20% of total vegetation. The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.
