Integrated Land Change Monitoring

Satellite images that have been continuously acquired for many decades represent a unique record of our planet’s surface. At EROS, we analyze satellite and other data to determine not only how the Earth’s land cover has changed over time, but also the driving forces behind the changes. Understanding the how and why of past land cover and land use change makes it possible to more accurately predict future changes and their impacts on people, environments, and resources. 

Land Change Monitoring, Assessment, and Projection

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 EROS Center.

Alaska North Slope LiDAR

High-resolution light detection and ranging (lidar) elevation data were acquired along the north coast of Alaska between 2009 and 2012. The lidar acquisition, from Icy Cape, Alaska to the United States/Canadian border, comprised approximately 11,000 km2. The airborne lidar data were acquired in support of the U.S. Geological Survey...

3D Topobathymetric Digital Elevation Model for Lake Powell Storage Capacity Assessment

To support the modeling of the Colorado River water storage area capacity tables by the U.S. Geological Survey (USGS) Utah Water Science Center, the USGS Earth Resources Observation and Science (EROS) Center created a 3D high-resolution topobathymetric digital elevation model (TBDEM) for Lake Powell. Located in south-central Utah and north-...

LCMAP Change Stories: Gone in 60 Seconds

At first glance, the most striking patterns in land cover change over time in this animation of the Oso, Washington area would appear to be forest harvest and regrowth, but a more dramatic change emerged in 2014.

LCMAP Change Stories: It's a Sprawl World After All

The man-made Florida playland of Walt Disney World has grown outward on all sides since the amusement park’s construction commenced in the 1960s. Much of that growth has overtaken the wetlands, tree cover and grassland/shrublands near Orlando.

Ranking Features Based on Magnitude of Change

Each of the polygons in the topographic change inventory has numerous attributes associated with it. These attributes allow a ranking of features based on the magnitude of change, as measured by polygon descriptors (area and volume) and changes in terrain parameters (elevation, relief, slope, aspect). The ability to do such a ranking points out one of the advantages of producing spatially...

Topographic Change Viewer

The USGS has developed a national inventory of significant topographic changes based on seamless multi-temporal elevation data and land cover data. The NED and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States.
