In LCMAP, monitoring refers to the incorporation of every clear Landsat observation to determine if current land conditions diverge from those observed in the past. A suite of operational automated algorithms is used to identify land change and to characterize a variety of land cover types, uses, and conditions across the United States. The monitoring product suite provides land change science information critical to understanding spatial and temporal characteristics related to the type, intensity, condition, and location of land use and cover changes. By using the full historical depth of the Landsat archive from the Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), and Operational Land Imager (OLI) sensors, LCMAP monitoring can reveal trajectories of land change from the early 1980s to the present day. The product suite and services are capable of monitoring land cover change as it occurs as well as identifying the type of disturbance process(es) impacting a location.
