GeographicLib's geoid height function in Python, C, and JavaScript

GeographicLib is a library that contains, among many other features, one especially useful feature: computing the height of the WGS84 geoid above the ellipsoid.

At various times over the course of the past 5 years, I needed this feature in projects that were written in Python, C, and JavaScript. Since the guts of the code is not too long, I translated the feature from GeographicLib's C++ into each of those other 3 languages.

  • The Python implementation was written on 2009-11-07
  • The C implementation was written on 2011-06-10
  • The JavaScript implementation was written on 2015-10-29

Since GeographicLib is licensed under the LGPL, all of this derived work is as well.
