Explore the invisible world
Landsat sees things on the electromagnetic spectrum, including what's invisible to the human eye.
Different spectral bands yield insight about our precious and continually changing earth. Scientists and GIS analysts use Landsat to keep an eye on places like the Cambridge Gulf in Australia (right), where mangroves are threatened by cyclones and industrialization.
Travel through time
Landsat takes images of every location on earth once every 16 days, so we can see how places change over time.
Farmers and analysts can measure how crops are developing in places like Bakersfield, California (left). Different crops appear in different colors at specific times in their growth cycle. Variations indicate stress due to lack of water or fertilizer. This analysis helps not only farmers, but also analysts who predict market prices based on supply.
Massive in scope
Landsat's work is epic in scale. In over 4 decades, it has amassed over a petabyte of data, with over 4 million scenes and counting.
