... (NLCD) 30-meter national dataset. Smucker et al. Generation of NLCD 2006 helped identify and correct issues in the NLCD 2001 land cover and impervious surface products only, and no changes were made to the NLCD 2001 canopy product. See additional documentation at https://erams.com/documentation/wrap NLCD: Clip. To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nation’s land resources, the USGS has designed a new generation of NLCD products named NLCD 2016. Additional products include percent developed impervious, percent tree canopy, and land cover change. No new imperviousness products for Alaska, Hawaii and Puerto Rico are available from NLCD 2016. New for NLCD 2016 is an impervious surface descriptor layer. NLCD 2016 Data .. any guesses? 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. That layer, updated to 2016, covers the entire continental US in the Albers projection. Results from this study confirm the robustness of this comprehensive and highly automated procedure for NLCD 2016 operational mapping. USA. Crosswalk to NLCD classes ... • Herbaceous wetland decreases about 677 km2 or -0.6% between 2001 and 2016 • NLCD wetland mapping captured wetland change in … Class Code 21 – areas with a mixture of some constructed materials, but mostly vegetation in the form of lawn grasses. NLCD serves as the definitive moderate resolution land cover database for the U.S., developed from Landsat data at a 30-m pixel resolution. Read 19 answers by scientists with 14 recommendations from their colleagues to the question asked by João Miguel Neri Camilo Moreira on Apr 17, 2016 The performance of the developed strategies and methods were tested in twenty World Reference System-2 path/row throughout the conterminous U.S. An overall agreement ranging from 71% to 97% between land cover classification and reference data was achieved for all tested area and all years. 2011. 5.0 Comparison of NLCD 2016 and the UVM SAL High Resolution Data 13 5.1 Categorical Land Cover Comparison 13 5.2 The UVM SAL “Low Vegetation” Class Compared to NLCD 17 5.3 Impervious Surface Area Comparison 17 6.0 The Chesapeake Bay 10 Meter Hybrid Land Use Product 18 7.0 Conclusions and Recommendations 20 7.1 NLCD 2016 versus NLCD 2011 20 The NLCD 2016 design aims to provide innovative, consistent, and robust methodologies for production of a multi-temporal land cover and land cover change database from 2001 to 2016 at 2–3-year intervals. This descriptor layer identifies types of roads, core urban areas, and energy production sites for each impervious pixel to allow deeper analysis of developed features. Use slider to choose a data year to view. The NLCD scheme includes multiple forest and wetland categories as well as some information about developed and agricultural land uses. The National Land Cover Database (NLCD): NLCD is a land cover monitoring database, providing generalized land cover (16 classes) and impervious cover (1% increments) for the U.S. for 2001, 2006, and 2011. To address accuracy concerns of the National Land Cover Dataset (NLCD), this case study compares impervious surface from the NLCD to a Detailed Land Cover Dataset (DLCD) for the Town of Blacksburg, Virginia over two time periods (2005/2006 and 2011) at spatial aggregation short url for this page: https://go.usa.gov/xpXbJ. 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). Clear Selected Report Print or Embed Map . To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nation’s land resources, the USGS has designed a new generation of NLCD products named NLCD 2016. 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). These nationally standardized, raster-based inventories of land cover are derived from multiple dates of Landsat satellite imagery and provide 7 epochs of land cover data for years 2001, 2003, 2006, 2008, 2011, and 2016. NLCD serves as the definitive moderate resolution land cover database for the U.S., developed from Landsat data at a 30-m pixel resolution. NLCD has also produced forest canopy density (1% increments) for 2001 and 2011. Logical Consistency: The NLCD 2016 final seamless products include: 1) NLCD 2016 Land Cover; 2) NLCD 2016 Impervious Surface; 3) NLCD 2016 Land Cover Change Index. From the USGS: The NLCD 2016 suite of Conterminous U.S. (CONUS) land cover and impervious products have now been released. Landcover classified as impervious by the 2011 NLCD Percent Developed Imperviousness Layer was used for this map. 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. 3. These data were generated by using the 2011 National Land Cover Dataset (NLCD) and Esri ArcGIS 10.2.2. The USGS, working in partnership with the Federal interagency Multi-Resolution Land Characteristics (MRLC) Consortium, is developing the National Land Cover Database (NLCD) 2016.

COUNTY 8.7% or 24 square miles. These land use layers for each state are clipped from the National NLCD layer provided by the Multi-Resolution Land Characteristics Consortium (MRLC) here. NLCD 2006 quantifies land cover change for the conterminous U.S. between the years 2001 to 2006. To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nation’s land resources, the USGS has designed a new generation of NLCD products named NLCD 2016.
