xyz2llh - Converts geocentric X, Y, Z to or from geodetic latitude,
longitude, and height.
xyz2llh {-dhrw} coordinates
where:
-d = print deg min sec rather than decimal degrees,
-h = print help message,
-r = input lat, lon, and hgt, output will be X, Y, Z,
-w = output longitude is west rather than east longitude.
DESCRIPTION
xyz2llh is a command-line driven program suitable for manual use
or as a command in a script. The conversion functions are those distributed
by the U.S. Naval Observatory but were converted from Fortran to C.
These functions have the desirable characteristic that they are non-iterative.
NOTES:
The GRS80 semi-major axis and flattening for the are are used.
EXAMPLES
Values returned by the program will be shown in fixed width font.
