Satellite imagery has recently become more accessible, and some data can be freely found on the Internet. Free satellite images are widely used not only in educational and scientific circles, but also in the commercial sector. Free remote sensing Data includes satellite images with a spatial resolution less than 10 m, such as data from the Sentinel and Landsat satellite programs.

Many people still don't know where they can find free satellite images. We present you the list of services where anyone can choose the necessary satellite images.

United States Geological Survey (USGS)

The United States Geological Survey (USGS) has the oldest and largest archive of free spatial data. You can access it using the EarthExplorer service ( https://earthexplorer.usgs.gov). The service provides access to data from USGS-NASA satellites, as well as open data from the Indian space research organization (ISRO) and the European Space Agency (ESA). There are also archived images from high-resolution commercial satellites IKONOS-2, OrbView-3 and Spot. They have incomplete coverage and a very limited period and are more suitable for educational purposes. In the service, you can filter data by date, cloud percentage, and number of sensors, and data can be downloaded immediately from a site with a processing level of Level-1, 2, or 3. The USGS also has an additional portal for downloading materials – GloVis.

LandViewer portal

LandViewer portal ( https://eos.com/landviewer) is represented by EOS, one of the leading space imaging distribution companies. The service provides access to free data from optical satellites CBERS-4, Sentinel-2, MODIS/NAIP, Landsat-7, 8, and the Sentinel-1 radar survey satellite. They are available for download as " raw " scenes and mosaics. In addition to free data, the portal offers data from commercial ultra-high-resolution satellites Kompsat-3, SuperView, GaoFen-2 and TripleSAT. The portal interface is more friendly than in the USGS portal. In addition, Analytics is available on the portal. Satellite images can be visualized using more than 20 combinations and indexes, such as NDVI, NBR, SAVI, and others.

Sentinel Hub: EO Browser and Sentinel Playground

Sentinel Hub has two portals for working with free data: EO Browser and Sentinel Playground. EO Browser allows you to view, analyze and download materials from Sentinel, Landsat -5, 6, 7 and 8, Envisat, Meris, MODIS, GIBS and Proba-V satellites of medium and low resolution. The Sentinel Playground portal allows you to view and analyze mosaics of images obtained from Sentinel-2, Landsat-8, and MODIS. You can apply up to eight channel combinations for each image.

Copernicus Open Access Hub 

The Sentinel snapshot collection is stored on the Copernicus Open Access Hub ( https://scihub.copernicus.eu). The portal provides the ability to search, view and download materials from the entire Sentinel satellite constellation. The interface and functionality of the service is quite limited, but it contains the latest satellite images.
