The decrease of lake Chad as documented during twenty years of manned space flight Academic Article uri icon


  • Space photography has been sucessfully used to extend the space remote sensing data base for environmental monitoring by a decade. In this study of Lake Chad, space photographs were digitized and registered to a topographic base map before water classifications were performed. From 1966 to 1985 we observed over a 21,000 square kilometer decrease in lake surface area. 1989 Taylor & Francis Group, LLC.
