The AEGOS project aims at setting-up the preparatory phase for the building of an information system containing and making accessible data and knowledge on African geological resources including mineral resources, raw material, groundwater and energy (georesources). This information is/has been collected through numerous initiatives by both African countries, regional, international and European organisations collectively, and is a unique archive of Africa related geoscientific observation data which primarily need to be shared with African partners. Developing capacity building activities in the domain of Earth observation in developing countries is a priority.
