Recent Advances in Remote Sensing & Gis in Sub-Sahara Africa

This book focuses on impending serious problems of socio-economic conditions in the sub-Saharan countries utilising remote sensing and GIS techniques. In Africa, the use of remote sensing data and analysing techniques such as GIS is essential for any studies that involve an extensive area because more often than not, topographic maps at a scale of 1:50,000 or larger are not available for detailed mapping on the ground. In addition, basic socio-economic and physical data, such as census data, environmental data, and infrastructure data, are lacking or not kept updated for modelling analyses.
