There is a wealth of satellite imagery of earth available, but it's not always\nobvious how or where to obtain those images. Quite a lot of imagery is available\nfor free and free imagery usually offers a good starting point for any new project.\nCommercial imagery is often available at higher resolutions and commercial satellites\nwill often pass over your point of interest more frequently.
\nThe Copernicus programme is a cooperation of the European Union and the European Space\nAgency (ESA) for Earth observation. ESA coordinates the acquisition and delivery\nof Earth observation data from space. Starting with Sentinel-1A in 2014, the Sentinel\nseries of satellites delivers a wide range of Earth Observation (EO) data for\nenvironmental and civil purposes.
\nThe Copernicus Open Access Hub provides complete, free and open access to Sentinel-1,\nSentinel-2, Sentinel-3 and Sentinel-5P user products. Both graphical User Interfaces\nand API access to the data are available.
\nCopernicus also provides access to the data to other providers and the user interfaces\nof some of the other providers are easier to use.
\nSentinel Hub provides a cloud API for Satellite Imagery. As well as access to data from\nthe Sentinel satellites, Sentinel Hub offers access to Landsat and and other data, including\nsome commercial satellite providers. They offer free and various levels of paid plans,\ndepending on use cases. They have an Earth Observation online browser that makes it\none of the easier services to use when selecting and downloading EO data.
\nEarthExplorer (EE) provides online search, browse display, metadata export, and data\ndownload for earth science data from the archives of the U.S. Geological Survey (USGS).\nEE provides an online user interface for searching, viewing, and downloading data.
\nAs well as access to Satellite data from Landsat, EE provides access to historical data\nfrom other USGS and NASA satellite missions, as well as aerial photography. EE also\noffers access to ESA and ISRO data, as well as data from some commercial providers.\nThe breadth of data available can be overwhelming and the user interface is not the\nmost user friendly.
\nGoogle Earth Engine hosts satellite imagery and stores it in a public data archive\nthat includes historical earth images going back more than forty years. The images,\ningested on a daily basis, are then made available for global-scale data mining.
\nEarth Engine also provides APIs and other tools to enable the analysis of large\ndatasets.
\nWhile the above selection will get you started, there are many other source of\nEO data, free and commercial. We think the above selection provides good global\ncoverage and are among the easier to use. Some notable others include:-
