National Land Imaging Program

Our Nation’s economic security and environmental vitality rely on continuous monitoring of the Earth’s continents, islands, and coastal regions. 

The USGS National Land Imaging (NLI) Program makes it possible to record, study, and understand how the surface of the Earth is changing at local, regional, national and global scales.

Brief communication: Not as dirty as they look, flawed airborne and satellite snow spectra Brief communication: Not as dirty as they look, flawed airborne and satellite snow spectra

Key to the success of spaceborne missions is understanding snowmelt in our warming climate, as this has implications for nearly 2 billion people. An obstacle is that surface reflectance products over snow show an erroneous hook with decreases in the visible wavelengths, causing per-band and broadband reflectance errors of up to 33 % and 11 %, respectively. This hook is sometimes mistaken...
