LCMAP represents the next generation of land cover and change mapping, developed by the USGS Earth Resources Observation and Science (EROS) Center. The effort synthesizes decades of advancements in remote sensing technology to provide timely information on how, why and where the planet is changing.

Initial LCMAP products will leverage Landsat Analysis-Ready Data (ARD) and the Continuous Change Detection and Classification (CCDC) algorithm to create independently-validated datasets and applications to enhance our understanding of natural and man-made change and help address pressing questions of land and resource management.

The website announcement comes in anticipation of the release of LCMAP sample data this spring, followed by a full product suite over the summer. The site includes product descriptions, explanations of the initiative and its six core areas of study, LCMAP and Landsat ARD-related publications, and slides from the LCMAP webinar and workshop that took place in November of 2018.

Soon to be released LCMAP products for the conterminous United States include primary and secondary land cover classes and confidence layers for each, annual land cover change, time of spectral change and time since last change, change magnitude, spectral stability period and model quality data.

LCMAP is an initiative of the USGS EROS Center, with partners including Boston University, South Dakota State University, Texas Tech University, the U.S. Fish and Wildlife Service and the State University of New York’s College of Environmental Science and Forestry.
