AbstractProjections which preserve the true bearing at any point to one specified fixed point have generally been regarded as amusing curiosities, because their special property is of no particular value for normal mapping purposes. There is not much reference to such projections in the literature. J. I. Craig's“Mecca”projection, and the Weir Azimuth Diagram, are probably the best known examples, and these are to be regarded as graphical aids for certain purposes, religious devotion and astronomical observation respectively.
