NLCD 2016 represents the latest evolution of NLCD land cover products focused on providing innovative land cover and land cover change data for the Nation. The NLCD 2016 update also characterizes proportion of urban imperviousness and tree canopy cover. Developed classes in these years are directly derived from and updated following the impervious surface cycle. The USDA, NASS Cropland Data Layer (CDL) is a raster, geo-referenced, crop-specific land cover data layer. This is a Non-Federal dataset covered by different Terms of Use than Data.gov. NLCD 2016 offers 7 integrated epochs of land cover for years 2001, 2003, 2006, 2008, 2011, 2013, and 2016. 2. New for NLCD 2016 is an impervious surface descriptor layer. Additional products include percent developed impervious, percent tree canopy, and land cover change. These data contain percent tree canopy estimates, as a continuous variable, for each pixel across all land covers and types and are generated by the United States Forest Service (USFS). Specifically, we have lowered the tree canopy cover threshold for exclusion from 40 to 25%. 5. Spatial information may not meet National Map Accuracy Standards.

During this 15-year period, 7.6 percent of the conterminous U.S. changed land cover at least once. (Read More), NLCD 2016 Shrub Component products characterize the percentage of each 30-meter pixel in the Western United States covered by shrub, herbaceous, bare ground, litter, sagebrush, big sagebrush and annual herbaceous, along with estimating shrub height and sagebrush height. This structure ensures that Landsat Level-1 products provide a consistent archive of known data quality to support time-series analyses and data “stacking”, while controlling continuous improvement of the archive and access to all data as they are acquired. National Land Cover SHP. As the metropolitan area expanded, Chester County became one of the suburban frontiers of Philadelphia, with developed land cover concentrated along transportation corridors that were first railroad lines and later U.S. and state highways, such as U.S. 30 and more recently I-76 (.
