Digital Earth Africa data moved to Amazon Web Services facility in Cape Town to optimise availability and accessibility
With the opening of Amazon Web Services (AWS) Cape Town region, countries across Africa now have access to locally stored analysis-ready satellite data, freely available through the Digital Earth Africa (DE Africa) platform.
The movement of Sentinel-2 data to the AWS facility in Cape Town allows DE Africa to store data closer to our users, enabling them to access and analyse information more quickly. By leveraging AWS, DE Africa can store, process and make available petabytes of data for all of Africa in an environment that is reliable and scalable.
Now that the analysis ready data is available in Cape Town it can be accessed through multiple pathways, including with direct access through Esri’s Geoportal.
AWS is supporting the DE Africa project as part of the Amazon Sustainability Data Initiative, which aims to accelerate sustainability research and innovation. The availability of the analysis-ready Sentinel-2 data is made possible through international collaborations with Sinergise, Element 84 and the Committee on Earth Observation Satellites (CEOS).
Sinergise has processed data to the CEOS Analysis Ready Data (CARD) specifications over Africa using the European Space Agency’s Sen2Cor software. This back- processing has opened the archive of Sentinel-2 data and proved the concept for global processing, making millions of Sentinel-2 scenes available as part of the AWS Public Dataset programme. Element 84 have converted the Sentinel-2 data from JPEG2000 to cloud-optimised GeoTIFFs, which include spatio-temporal asset catalogue (STAC) metadata to make the data interoperable for the Earth observation community.
