Land Remote Sensing Program
The USGS is fostering the use of land remote sensing technology to meet local, national, and global challenges.
The Department of the Interior (DOI) and the U.S. Geological Survey (USGS) have requested a Federal Advisory Committee to review USGS's current free-and-open policy for user access to Landsat data.
The William T. Pecora Award is presented annually to individuals or groups that have made outstanding contributions toward understanding the Earth by means of remote sensing. Nominations for the 2018 award must be received by June 15, 2018.

Landsat 8 is demonstrating promising new capabilities for water quality assessment. Satellite-based instruments allow for more frequent observations over broader areas than physical water sampling. Four federal agencies—NASA, NOAA, EPA, and USGS—are joining forces to develop an early warning system for toxic and nuisance algal blooms. Through this project, satellite data on harmful algal blooms will be converted to a format that stakeholders can use through mobile devices and web portals. This will improve detection of these blooms and help researchers better understand the conditions under which they occur.
USGS scientists used Landsat data to determine that forests, wetlands and farms in the eastern U.S. naturally store 300 million tons of carbon a year, which is nearly 15 percent of the greenhouse gas emissions EPA estimates the country emits each year or an amount that exceeds and offsets yearly U.S. car emissions. In conjunction with the national assessment, USGS has a LandCarbon site which allows users to see the land and water carbon storage and change in their ecosystems between 2005 and 2050 in the lower 48 states. Biological carbon storage - also known as carbon sequestration - is the process by which carbon dioxide (CO2) is removed from the atmosphere and stored as carbon in vegetation, soils and sediment. The USGS estimates the ability of different ecosystems to store carbon now and in the future, providing vital information for land-use and land-management decisions. Management of carbon stored in our ecosystems and agricultural areas is relevant both for mitigation of climate change and for adaptation to such changes.
