Land Change Monitoring, Assessment, and Projection


Land Change Monitoring, Assessment, and Projection (LCMAP) represents a new generation of land cover mapping and change monitoring 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 and change variables than previous efforts.

LCMAP Captures ‘Stories of Change’ with New Datasets

If a new homeowner wants to know the history of their abode, there are places to turn.

County offices list ownership details and building permits, showing the dates of additions, fences and the like. If the house is old enough, local historical societies may even have archived photographs of the home’s exterior at various points in time.

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...
