Full coverage of Africa is now available in a set of 8 DVDs. The Orthorectified Landsat Thematic Mapper Mosaics, or Zulu 7 mosaics as we prefer to call them, consist of high resolution Landsat 7 images processed in the infrared spectrum and enhanced for maximum contrast. Since of the infrared processing the colours are not real (False Colours): for instance vegetation is represented by shades of purple (not pleasing to the eye but indicating different vegetation types e.g. sugarcane fields are light pink), cold water is black while while warm water is light blue. Resolution is 15m/pixel. Individual DVDs are available at R150 (USD$25) each plus postage.
