The USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative has released the third update to its conterminous United States (CONUS) science products, adding the most recent calendar year of data to an unparalleled annual land cover and land surface change time series that stretches back to 1985.
Collection 1.3 extends LCMAP’s record to 37 years, characterizing the landscapes across CONUS at 30-meter resolution from 1985-2021. The 10-product suite can be used to capture the dynamics of wetlands in growth or decline, characterize the ephemeral impacts of hurricanes or rapidly-shifting mining operations, track the pace of coastal erosion or urban growth, observe the progression of fires, monitor recovery from mudslides and wildfires, and much more. LCMAP products can also serve as a complement to other USGS Landsat-based mapping efforts, such as the National Land Cover Database, LANDFIRE, Monitoring Trends in Burn Severity, and others.
Tiled and bundled LCMAP Collection 1.3 data products are now available through EarthExplorer. The data are also available for visualization and download using the LCMAP Web Viewer and Web Map Service (WMS) Endpoint. Full mosaics over CONUS by product-year are available through the LCMAP Mosaic Download Site. The mosaics are distributed as internally tiled and compressed GeoTIFFs that allow direct access to the data.
Additional reference data for Collection 1.3 from 2019-2021 are being collected and will be made publicly available at a later date. The results of a validation assessment of the LCMAP Collection (1985-2021) will also be made available in the future through ScienceBase.
