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 bare ground fractional percentages. release of NLCD provides important new information change patterns across CONUS from 2001 to 2016. For seven epochs were concurrently generated years 2001, 2004, 2006, 2008, 2011, 2013, Products reveal that...
The National Land Cover Database (NLCD) 2016 provides a suite of data products, including land cover and change the conterminous United States from 2001 to 2016, at two- three-year intervals. development this product is part an effort meet growing demand for longer temporal duration more frequent, accurate, consistent information. To accomplish this, we designed new strategy developed comprehensive methods, models, procedures NLCD implementation. Major steps in consist preparation, detection...
The National Land Cover Database (NLCD), a product suite produced through the MultiResolution Characteristics (MRLC) consortium, is an operational land cover monitoring program. Starting from base year of 2001, NLCD releases database every 2-3-years. recent release NLCD2019 extends to 18 years. We implemented stratified random sample collect reference data for 2016 and 2019 components at Level II I classification hierarchy. For both dates, overall accuracies (OA) were 77.5% ± 1% (± value...
National Land Cover Database (NLCD) 2019 is a new epoch of national land cover products for the conterminous United States. Image quality fundamental to any product. preprocessing has often taken considerable proportion overall time and effort this kind project. An approach prepare image inputs NLCD production was developed ensure efficiency operational production. Here, we introduce comprehensive strategy produce clear Landsat composite images First, median-value compositing method. Second,...
The National Land Cover Database (NLCD) 2016 products show that, between 2001 and 2016, nearly half of the land cover change in conterminous United States (CONUS) involved forested areas. To ensure quality NLCD products, it is important to accurately detect location time forest disturbance. We designed a comprehensive strategy integrate continuous series detection method discrete 2-date produce 1986–2019 disturbance product, which shows most recent date years 1986 2019 for every 2- 3-year...
We estimated urbanization rates (2001–2006) in the Gulf of Mexico region using National Land Cover Database (NLCD) 2001 and 2006 impervious surface products. An improved method was used to update NLCD product associated land cover transition between 2006. Our estimation reveals that increased 416 km2 with a growth rate 5.8% Approximately 1110.1 non-urban lands were converted into urban land, resulting 3.2% increase region. Hay/pasture, woody wetland, evergreen forest represented three most...
Droughts that are hotter, more frequent, and last longer; pest outbreaks extensive common; fires extensive, perhaps severe have raised concern forests in the western United States may not return once disturbed by one or of these agents. Numerous field-based studies been undertaken to better understand forest response changing disturbance regimes. Meta-analyses provide broad guidelines on biotic abiotic factors hinder recovery, but study-to-study differences methods objectives do support...
The U.S. Geological Survey (USGS) has developed the National Land Cover Database (NLCD) to provide consistent land cover and change products for nation since 2001. As one of in NLCD, percent impervious surface area (ISA), which was estimated with Landsat imagery, represents fraction human-made a 30-m grid been used quantify urban types extents United States. However, it is still challenge clearly determine intensity using remote sensing data spatial spectral resolutions similar part because...
