Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Landsat Science Products

The USGS is developing research-quality, applications-ready, Level-2 and Level-3 science products derived from Landsat Level-1 data, which can be used to monitor, assess, and project how changes in land use, land cover, and land condition affect people and nature.


Landsat 8 Level-1 (right) and Surface Reflectance (right) Image Comparison

Landsat image mosaics over the conterminous United States created using Landsat 8 Level-1 data (left) and Landsat 8 Level-2 Surface Reflectance data (right). Images were created in December 2014.

Level-2 Science Products are time-series observational data of sufficient length, consistency, and continuity to record effects of climate change, and serve as input into Landsat Level-3 Science Products.

Level-2 Surface Reflectance 

Measures the fraction of incoming solar radiation that is reflected from Earth's surface to the Landsat sensor. 

Level-2 Provisional Surface Temperature 

Represents the temperature of the Earth's surface in Kelvin (K). 


Level-3 products represent specific geophysical and biophysical properties of the land surface and contain parameters derived from systematic long-term measurements collected by satellite and aircraft platforms as well as in situ observational networks. 

Level-3 Dynamic Surface Water Extent 
(coming in 2018)

Describes the existence and condition of surface water.

Level-3 Fractional Snow Covered Area 
(coming in 2018)

Indicates the percentage of a pixel covered by snow.

Level-3 Burned Area 
(coming in 2018)

Represents per pixel burn classification and burn probability.
