The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. It identifies 33 mainland land cover classes (35 classes once the offshore Chatham Islands are included). The final integration step resolved class label issues pertinent to local environments (such as coastal areas), and, for land cover classes other than Water and Developed, ensured that all pixels in a segmentation object were in the same class. 4. Meanwhile, the U.S. National Geospatial-Intelligence Agency (formerly the National Imagery and Mapping Agency) hired a company called Earthsat (Now MDA Federal) to produce a 120-meter resolution, 13-class land use / land cover data set for the rest of the world. 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. The U.S. Geological Survey (USGS) released in late May its latest National Land Cover Database (NLCD) that documents the change in land cover in the Lower 48 states from 2001 to 2016. How does it work?
