Help me solve this puzzle (coordinates needed)

Here is the text:

and here is the picture part of the clue.

I’m assuming this puzzle is based on some sort of hex or base 10 system but I’ve tried all morning and my pathetic math skills have failed me. The answer will look something like this:

N 36° 38.??? W 121° 48.??? or
36° ??.??? 121° ??.???

Thanks
