Here I am, Jim Melka, showing a NASA/Malin Space Science topographical target map that was part of my request to the Malin Space Science Team to program the Mars Global Surveyor to image the footprint that I chose on the map. The purpose was to verify that a dark spot that I had imaged on Mars was a dark sand dune field in a crater.  Opposite is the MGS Context Image with the footprint displayed. Below is footprint image showing a massive dune field.
