Here, a traditional map would be useless, or hard to use. You don't want to get anywhere, just want to know (if you do) what you see ahead and below yourself. The illustration (right on the photo) shows the significant landmarks in this direction, an outline of what lays ahead, exactly as you see it from here.

Almost like a layer in an augmented reality browser. Except that this is just a piece of framed paper.

For every purpose and environment the suitable and most efficient map type.
