Acquired 11 November 2003, this wide-swath Advanced Synthetic Aperture Radar (ASAR) image is a mosaic of two images centred over West Africa and in particular the countries of Togo, Benin and Nigeria. At the top centre of the image is the Kainji Reservoir and the Niger River. Visible also as large bright areas are the major Nigerian cites: Ogbomosho (south of the Niger River), Ibadan (southeast) and Lagos (further south on the shore).
