Digital Earth Africa is entirely dependent on what is called Analysis Ready Data (ARD), which is Earth observation data that has been processed according to a set of requirements that allow immediate analysis. Currently, we take open and free ARD provided by international satellite programs, including;
And make them available through the DE Africa platform as Cloud Optimised GeoTIFFs with SpatioTemporal Asset Catalog (STAC) metadata. These datsets are provided with the intent and expectation of meeting the Committee on Earth Observing Satellites (CEOS) ARD specifications. The CEOS has been developing ARD specifications since 2016 to allow data to be processed to a more accessible and interoperable level. We use these datasets to create our data products, but we also make the datasets themselves available through the DE Africa platform.
DE Africa uses these datasets to create products and services at continental scale. By providing the data in a more accessible format, a larger range of non-specialist users will be able use its valuable information and insights. From simply identifying water resources for greater access to clean water through to the ability to regularly map food crops.
