Land Change Monitoring, Assessment, and Projection
Land Change Monitoring, Assessment, and Projection (LCMAP) represents a new generation of land cover and land use mapping from the U.S. Geological Survey’s Earth Resources Observation and Science (EROS) Center. LCMAP answers a need for higher quality results at greater frequency, with additional land cover variables and more detailed legends than previous efforts.
The LCMAP team held a workshop in November 2018 entitled “Continuous Monitoring of and Characterizing Land Change.” Workshop slides are now available for download.See the slides
LCMAP offers a suite of 10 annual data products that depict land cover and spectral change in the conterminous United States. The first LCMAP product suite will be released in mid-2019, with annual releases to follow.Learn more
The U.S. Geological Survey Earth Resources Observation and Science (EROS) Center is offering a fellowship opportunity for the research and development of innovative land change science techniques and applications.
The mapping and classification of land use and land cover has long been a primary duty for the U.S. Geological Survey (USGS), and remotely-sensed data at the Earth Resources Observation and Science (EROS) Center has served as the backbone of the Survey’s modern efforts.
In recent years, two advancements in remote sensing emerged that promise to revolutionize the field.
Analysis Ready Data: Enabling analysis of the Landsat archive
Data that have been processed to allow analysis with a minimum of additional user effort are often referred to as Analysis Ready Data (ARD). The ability to perform large scale Landsat analysis relies on the ability to access observations that are geometrically and radiometrically consistent, and have had non-target features (clouds) and poor...Dwyer, John L.; Roy, David P.; Sauer, Brian; Jenkerson, Calli B.; Zhang, Hankui K.; Lymburner, Leo
U.S. Landsat Analysis Ready Data
U.S. Landsat Analysis Ready Data (ARD) are a revolutionary new U.S. Geological Survey science product that allows the Landsat archive to be more accessible and easier to analyze and reduces the amount of time users spend on data processing for monitoring and assessing landscape change. U.S. Landsat ARD are Level-2 products derived from...
Forest harvest patterns on private lands in the Cascade Mountains, Washington, USA
Forests in Washington State generate substantial economic revenue from commercial timber harvesting on private lands. To investigate the rates, causes, and spatial and temporal patterns of forest harvest on private tracts throughout the Cascade Mountains, we relied on a new generation of annual land-use/land-cover (LULC) products created from the...Soulard, Christopher E.; Walker, Jessica; Griffith, Glenn E.
