The USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative has released the second 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.
LCMAP Adds Data for 2020 with Release of Collection 1.2
LCMAP Collection 1.2 marks the second of two planned updates for calendar year 2021. The collection extends LCMAP’s historical record of land cover and change to 36 years, characterizing the landscapes across CONUS at 30-meter resolution from 1985-2020. Processing for LCMAP Collection 1.3 will begin in early 2022, once all data from calendar year 2021 are made available.
Collection 1.2 extends the LCMAP time series, adding to the expansive list of scientific and research questions it can be used to investigate. 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, to 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.
The LCMAP team at EROS was able to produce the additional data approximately just months after the release of Collection 1.1.
Collection 1.2 data are now available through EarthExplorer. The new data will be added to and available through LCMAP’s interactive web viewer, alongside downloadable CONUS mosaics for each product. The results of a validation assessment of the LCMAP Collection (1985-2018) are also available through ScienceBase.
