This is the standard projection developed and used by the National Geographic Society for continental mapping. The distance from three input points to any other point is approximately correct.
The three selected input points should be widely spaced near the edge of the map limits.
Chamberlin Trimetric can only be used in ArcInfo as an OUTPUT projection because the inverse equations (Chamberlin Trimetric to geographic) have not been published.
You can't project an ArcInfo grid or lattice to Chamberlin Trimetric because the inverse equations are required.
Used by the National Geographic Society as the standard map projection for most continents.
