GAF demonstrates improved geological mapping with Sentinel data

GAF is currently completing the AMGI-ESA project. The African Mineral Geoscience Initiative (AMGI), promoted by the World Bank, is an initiative for the collection, the consolidation, the interpretation and the dissemination of national and regional geoscience data.

In this frame, GAF has developed products based on Sentinel data and other satellite data (optical, radar and DEM) in four demonstration areas in Africa in different climate zones. The products are integrated together in a database with geophysical and ancillary data for a synoptic interpretation.

This project successfully demonstrates on how to map large areas in a fast, efficient and area wide mode. The approach is of particular interest for regional geological surveys as well as for mineral exploration. The results will fuel the geological information catalogue for Africa and provide an important input to AMGI, which seeks the improved information access for governments, mineral stakeholders, and more generally for planners and natural resource managers – thus becoming an enabler for future investments in Africa. The project is funded by the European Space Agency (ESA).
