Workspace Method refellipsoidForAzimuth


Conversion of 3D ellipsoid to 1D curvature radius.

Calculates the curvature radius for the given latitude and azimuth
angle, and uses this to set a spherical reference ellipsoid
suitable for 1D calculations. The curvature radius is a better
local approximation than using the local ellipsoid radius.

The used expression assumes a geodetic latitude, but also
latitudes should be OK as using this method anyhow signifies
an approximation.
