Earth Resources Observation and Science (EROS) Center


At the USGS EROS Center, we study land change and produce land change data products used by researchers, resource managers, and policy makers across the nation and around the world. We also operate the Landsat satellite program with NASA, and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images.

Landsat Advisory Group Report Says Charging for Landsat Data Not Worth Economic, Societal Costs

Charging for Landsat data “would not be worth the economic, legal, societal or political costs that would be incurred,” and it makes more sense to investigate emerging proven technologies that could reduce the cost of Landsat missions, according to a report just released by the...

LANDFIRE remap prototype mapping effort: Developing a new framework for mapping vegetation classification, change, and structure

LANDFIRE (LF) National (2001) was the original product suite of the LANDFIRE program, which included Existing Vegetation Cover (EVC), Height (EVH), and Type (EVT). Subsequent refinements after feedback from data users resulted in updated products, referred to as LF 2001, that now served as LANDFIRE’s baseline datasets and are the basis for all...

Airborne waveform lidar simulator using the radiative transfer of a laser pulse

An airborne lidar simulator creates a lidar point cloud from a simulated lidar system, flight parameters, and the terrain digital elevation model (DEM). At the basic level, the lidar simulator computes the range from a lidar system to the surface of a terrain using the geomatics lidar equation. The simple computation effectively assumes that the...
