Our first operational data uses images captured by the European Commission Copernicus Sentinel-2 satellites. The twin Sentinel-2 satellites, launched in 2015 and 2017, provide multi-spectral optical observations at a spatial resolution of up to 10 metres. Since early 2018, the pair of satellites have been acquiring images over most of the land surface every five days. This creates a time-deep data resource that can be used to inform a variety of services.
We provide a time-series of Sentinel-2 data from 2017 onwards, making available 1.5 million scenes of data over Africa. The data is routinely updated, so anyone across Africa can use it to actively monitor changes to the environment and manage food and water resources.

Digital Earth Africa (DE Africa) has partnered with Sinergise, who manage the Sentinel-2 JPG2000 data in a collaborative arrangement with the ESA, to process more data that covers the African continent for the year 2017. DE Africa is also working with Element 84 who have converted Sinergise’s JPG2000 data for Africa to Cloud Optimised GeoTIFFS (COGs) – an open cloud native format that will enable greater accessibility for DE Africa’s users.
