"Fig. 7. The cubed sphere grid mapping maps the six faces of a cube to the surface of a sphere. The specific mapping shown here is non-orthogonal and generates a grid that varies less than 30% in grid cell area." alt text

For my purposes, I am looking for tile data based on this type of model/projection. A: Does a project like this exist? B: If it does not exist, is anyone interested in working on this projection with me? For my own opensource project, I wish to create just the cube seeing as I am rendering square tiles.

Do you have a source for that? I've seen something similar as an art project here:

Question "A": I've seen no tile server serving cubic globes.

But I'm sorry this is not a question about Openstreetmap, so you will not get an answer here. I did find some links that might help you:

  • use mercator instead check out how the slippy map work, especially how tile names are generated, they are vertically and horizontally aligned.
  • if you don't like that read up on projections on wikipedia, mercator vs. gnomic
  • there are people on the net that has done this.
  • You could try asking on gis.stackexchange they are probably better at open ended questions.
