A centralized database for downloading satellite imagery, such as Sentinel, Landsat and MODIS, as well as imagery-derived data products, such as land cover and digital elevation model data. Many—but not all—datasets are available globally, but may require additional processing for analysis.

How to access: 

Data can be downloaded in a variety of raster data formats, and accessing data requires a free USGS Earth Explorer account. If you have limited experience with GIS and/or coding, or are interested in visualizing and analyzing remote sensing datasets without downloading them, see EarthMap. For additional guidance on using Earth Explorer for searches, see this help document.
