is there a need for subj?
i implemented very accurate direct and inverse geodetic problem
routines (as well as geocentric (X, Y, Z) to geodetic (B, L, H) conversion)
i used bessel's method to derive the formulas
6 iterations for both direct and inverse routines is enough to get
full double precision
that is 1mm accuracy regardless of range (i.e. range = 1m..20000km)
to get acceptable accuracy, say, 2 iterations is enough (or even 1)
however there are several other aspects uncovered (area and perimeter,
projections, etc.)
