That layer, updated to 2016, covers the entire continental US in the Albers projection. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. 2. definitive Landsat-based, 30-meter resolution, land cover database for the Nation. No new imperviousness products for Alaska, Hawaii and Puerto Rico are available from NLCD 2016. 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. 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). Since new 2016 versions of NLCD products for all years have now been released, the decision was made to refrain from reprojecting this dataset into the County's standard NAD83 HARN projection. Therefore, date-sensitive fields such as feature count and date of last update may not be up-to-date. National Land Cover Data (NLCD) New suite of land use change products NLCD 2016 represents the most comprehensive land cover database ever produced by the USGS and was specifically developed to meet the rapidly growing demand for land cover change data.

Comprehensive research was conducted and resulted in developed strategies for NLCD 2016: a streamlined process for assembling and preprocessing Landsat imagery and geospatial ancillary datasets; a multi-source integrated training data development and decision-tree based land cover classifications; a temporally, spectrally, and spatially integrated land cover change analysis strategy; a hierarchical theme-based post-classification and integration protocol for generating land cover and change products; a continuous fields biophysical parameters modeling method; and an automated scripted operational system for the NLCD 2016 production. Stehman, C.G. 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 serves as the definitive moderate resolution land cover database for the U.S., developed from Landsat data at a 30-m pixel resolution. Additional products include percent developed impervious, percent tree canopy, and land cover change. Let’s use the new USA NLCD Impervious Surface Time Series layer to find out what areas have changed the most in the Houston area since 2001. NLCD is generated in cooperation with the Multi-Resolution Land Characteristics Consortium a partnership of Federal agencies working together to produce current, nationally consistent, land cover products for all 50 states and Puerto Rico.NLCD is used for thousands of applications that require information on landcover location or where it is changing. I’ve been eagerly awaiting the release of the new NLCD 2016 land cover data - the website on the consortium just says “early 2019”.
