Recently I rediscovered Geocaching as a hobby. It is a nice reason to walk around in a city or in nature and discover interessting facts and have a nice time in general.
When searching for clues for a Mystery cache, I needed to calculate
a destination from a starting point, bearing and distance.
With my nautical background, this used to be a regular operation for me. I prefer to use Python scripts for calculations like this so the process is repeatable.
So I started coding this package.
I used the loxodrome and great circle formulas on Movable Type Scripts. Those I recognized from my studies at a Nautical Collage.
