This was generated from the file ldem_80s_20m.jp2 from the Planetary Data System. It was reduced to 200 meter resolution, then processed by halves to get a 1 x 2 aspect ratio for each half. It is a relief plot colored by height. The two halves were different thicknesses, so the seam shows. X Y and Z are in proper proportion. Click for full size, about a half percent of the original 30400 x 30400 dataset.
