Solving Puzzle Geocaches Programmatically

November 1st 2019 Geocaching GPS

Puzzle geocaches often require some calculations to determine the final coordinates. That's particularly common in GeoArt trails. Although some of these trails can be quite long, I had always solved them manually. Until I encountered the Pirate Cruise trails near Split in Croatia, that is. Almost 500 caches requiring geodetic calculations were too many to do by hand. I decided to find a way to automate the calculations.
