Land Change Monitoring, Assessment, and Projection

Home

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.

Tracking Change Across Time and Space with LCMAP

The U.S. Geological Survey took a bold step toward documenting change across the landscape with the launch of the first Landsat satellite in 1972. Since then, the orbiters have collected nearly five decades of imagery.

From Concept to Reality, USGS Land Change, Monitoring, Assessment and Projection Pushes Boundaries in Service of Science

More than a decade ago, Tom Loveland sat down to sketch out a few thoughts on land change and the Landsat archive.

The archive was and remains rich with history, adding new observations of the entire planet every eight days. But at that point, Landsat-based land change research was about comparing points in time – this year versus five years ago, to 10 years ago, and so on.

Land change monitoring, assessment, and projection

There is a pressing need to monitor and understand the rapid land change happening around the world. The U.S. Geological Survey is developing a new capability, called Land Change Monitoring, Assessment, and Projection (LCMAP), to innovate the understanding of land change. This capability is the Earth Resources Observation and Science Center's...

Training data selection for annual land cover classification for the LCMAP initiative

The U.S. Geological Survey’s Land Change Monitoring, Assessment, and Projection (LCMAP) initiative characterizes changes in land cover, use, and condition with the goal of producing land change information that improves understanding of the earth system and provides insight into the impacts of land change on society. For LCMAP, all available high-...

Lessons learned implementing an operational continuous U.S. national land change monitoring capability: The LCMAP approach

Growing demands for temporally specific information on land surface change are fueling a new generation of maps and statistics that can contribute to understanding geographic and temporal patterns of change across large regions, provide input into a wide range of environmental modeling studies, clarify the drivers of change, and provide more...
