In this episode, we are delighted to have Prof. Tsehaie Woldai as out guest. Prof. Woldai founded the African Association of Remote Sensing of the Environment AARSE) and has decades of experience in remote sensing in Africa, Europe and all over the world. He says many African countries have their own satellites but often do not share the data, with South Africa, Egypt, and increasingly Nigeria noted as exceptions, while some launches are for prestige. Students reportedly complain they still cannot access national satellite data, so people rely heavily on free resources like Sentinel data and tools such as SNAP and QGIS.We observe very little radar remote sensing output from Africa but we are unsure why. They argue radar is important for hazards, archaeology, mining, and interferometry, and also highlight limited access to LiDAR (often kept secret, with only small drone-based efforts) and scarce hyperspectral data, hoping Europe or the U.S. provide more.
