NASA's interpretation of the Jules Verne classic. This Image Gallery exhibit includes A(Alexandria, the ancient Egyptian port city) to Z (Wellington, New Zealand) and 78 other Earthly points in between. See the world as it looks from an orbiting satellite in full color and with brief explanations.
Magellan Image Data http://history.nasa.gov/JPL-93-24/ch2.htm
Explains how orbit determinations based on short data arcs from a single day's tracking provide the basis for SAR processing, locating individual pixels, and mosaicking the image strips. The final data are sufficiently accurate to allow mosaicking of image data strips by a process of dead reckoning without the use of tie points.
