+OzAllens Posted January 29, 2021 Share Posted January 29, 2021 Hey all, I've just started with geocaching recently and have come across a couple of mystery caches that require you to apply an offset to find the final location, eg. S-345 E+123. Could someone explain how to do this please, because nothing I've tried seems right and Google hasn't helped... Quote Link to comment

I would imagine you'd start with the published coordinates and then subtract 345 from the decimal part of the minutes south and add 123 to the decimal part of the minutes east. 2 3 Quote Link to comment
+mustakorppi Posted January 29, 2021 Share Posted January 29, 2021 And when you're doing this type of math, it's worth understanding that the minutes part is minutes: the numbers go from 0.000 to 59.999. So if you have N40 59.999 and are told to add +1 to latitude, you get N41 0.000. 1 1 Quote Link to comment
