GeographicLib is a small C++ library for: geodesic and rhumb line calculations; conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates; gravity (e.g., EGM2008) and geomagnetic field (e.g., WMM2020) calculations.

I have used this to calculate Ocad mapping software angle correction GD: declination + convergence. Just updated WMM2015v2. Need to overwrite WMM2015 files ? Didn't find helps, but it looks that need to overwrite ?

Very fast and very accurate. Don't reinvent the wheel! Use this!

It has some useful for me, thanks!

Hi Visit the blog "Zona OpenGTS" (www) zona-opengts.blogspot.com Thanks !!!

GeographicLib is a great library. I use it in FFGo to solve the geodetic inverse and direct problems, as well as to get magnetic declination data, and it works great! Having a ready-to-use algorithm that is more robust than the Vincenty algorithm for the geodetic inverse problem (and also more accurate, as I understood it) it invaluable. Thank you so much, Mr. Karney! (for info, I use the Python 3 implementation for geodetic calculations and call MagneticField as an external program to get magnetic declination data)
