Landsat sees the earth in a unique way. It takes images of every location in the world to reveal earth's secrets, from volcanic activity to urban sprawl.
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 (above), where mangroves are threatened by cyclones and industrialization.
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 (above). 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.
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.
With ArcGIS, you decide what you want to explore. Zoom to any location or bookmark, and try the tools in this simple web app.
Tip 1: Use the symbols to try different spectral views. Some are combinations of bands and others computed indices.
Tip 2: Use the time slider to see how places change over time.
Tip 3: For more details on any location, click identify, then click on the map.
Tip 4: Discover advanced features in the Landsat Explorer web app below.

Do you have large collections of imagery? ArcGIS can make them accessible, whether it's on-premises or in the Amazon cloud.
The Landsat program has amassed information on the changing earth since 1972, producing significant benefits in areas such as climate studies, agriculture and environmental monitoring. In March 2015, efforts by public and private sectors have provided a new way to access this resource.
Amazon Web Services (AWS) is now hosting Landsat imagery on publicly accessible S3 storage.
Esri is now making this Landsat imagery accessible in ArcGIS.
United States Geological Survey (USGS) manages the Landsat Program and makes the data freely available.
