Airy Projection
A Map Projection. The inverse equations for 
are computed by iteration. Let the Angle of the projection plane be 
. Define
 | (1) |
and compute the initial point by checking | (2) |
, take 
and iterate again. The first value for which 
is then the starting point. Then compute | (3) |
between evaluations is smaller than the acceptable tolerance. The (inverse) equations are thengiven by |  |  | (4) |
