----------------------------Original message---------------------------- One of our intrepid graduate students is trying to create a digital model of the area around Serengetti National Park. He would like to digitize the following sheets from the Tanzania Geological Map Series (1:125,000 scale): 13, 14, 23, 24, 25. He also needs the 1:250,000 topographic sheets covering the same area. He asked me for soil and vegetation maps at similar scales, but as near as I can tell they have not been produced at scales larger than 1:4,000,000. If I am wrong, please let me know. Is anybody willing to lend any of the above? Please respond to me personally rather than to the list.
