With no download required, Landsat Explorer users get instant, interactive access to an extensive collection of multispectral, multitemporal Landsat imagery.\r\n\r\nLandsat satellites have been collecting information about the earth's surface for almost 45 years. Each Landsat image contains multiple bands of spectral data gathered at different wavelengths. More than just offering pictures of the planet, Landsat's different bands can be combined and analyzed to learn about what is happening on the ground, beyond what the eye can see.\r\n\r\nLandsat Explorer is powered by Esri's Landsat image service, which includes more than 500,000 Landsat scenes with over 500 new scenes added daily. This is made possible in part by Amazon Web Services (AWS) and its Landsat on AWS dataset, which hosts Landsat 8 scenes (from 2013 to present) for free. Esri's Landsat image service combines this massive Landsat 8 collection with the Landsat Global Land Survey (GLS) datasets from 1975, 1990, 2000, 2005, and 2010. The result is four decades of global coverage. And while the Landsat Explorer app is a simple way to interact with this dataset, the Landsat image service can also be used directly in a wide range of other Esri apps and software, including ArcGIS Pro.\r\n\r\nBeyond enabling users to instantly view half a million Landsat images using different band combinations or enhancements, Landsat Explorer offers extensive analytical capabilities. The visualization and analysis tools let users do the following, all on the spot:\r\n
