Satellite Images of Continents
Each continent is (partially) shown here as seen from a satellite. The images are a "patchwork" of several different satellite images, which explains the lack of clouds. They are all taken at the same hour (noon or close), so there are almost no shadows.
Images taken from UNEP (2003), ISBN 92-807-2272-5 Selected Satellite Images of Our Changing Environment.
