• Summary:"The Cahill-Keyes projection is a polyhedral compromise map projection first proposed by Gene Keyes in 1975. The projection is a refinement of an earlier 1909 projection by Cahill. The projection was designed to achieve a number of desirable characteristics, namely symmetry of component maps (octants), scalability allowing the map to continue to work well even at high resolution, uniformity of geocells, metric-based joining edges, minimized distortion compared to a globe, and an easily understood orientation to enhance general usability and teachability." --Wikipedia, viewed March 1, 2014.
  
• Notes:Relief and depth shown by gradient tints.
  "The essence of Cahill-Keyes is total comparability of map to globe: not only every continent (like Cahill), but also every single 1° and 5° geocell (a Keyes refinement)."
