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. Developed classes in these years are directly derived from percent developed impervious surface and include a descriptor label that identifies the type of each impervious surface pixel. The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at the native 30-m spatial resolution of the Landsat Thematic Mapper (TM). We have developed a mask (see below) to apply to the future sagebrush cover layers. Alaska, Hawaii, and Puerto Rico data can be found in the previous Results from this study confirm the robustness of this comprehensive and highly automated procedure for NLCD 2019 operational mapping.
