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.

Satellite Data Show Promise as Guide for West African Crop Insurance

The Green Revolution has yet to spread across West Africa.

Much of the region relies on low-yielding, drought-resistant crops like sorghum and millet, some five decades after high-yield seeds, fertilizers and precision agriculture began to boost production across much of the planet.

40 years strong—Long-time Geoscience Australia, U.S. Geological Survey (USGS) partnership benefits both agencies and the world

In 1979, the Australian Government chose the city of Alice Springs to host a Landsat Ground Station because of its location in central Australia. This location enables satellite coverage of the entire Australian continent. Its antennas have played a key role in supporting international satellite programs over more than 40 years.

Climate sensitivity to decadal land cover and land use change across the conterminous United States

Transitions to terrestrial ecosystems attributable to land cover and land use change (LCLUC) and climate change can affect the climate at local to regional scales. However, conclusions from most previous studies do not provide information about local climate effects, and little research has directly quantified how LCLUC intensity within different...
