Ok, this will be easy...for me. Go to the coords and look at the sign. You will find 5 colors with two sets of numbers. The second column of numbers are all 3 digit (no decimal point numbers, that's the wrong column). Take all but the "green" 3 digit numbers and add them together. Take the green 3 digit number and take it to the 2nd power, then add it to the other sum. Now, you have a nice big number that we'll call A.
Multiply A by 86.8614727347.
You will have a 7 digit number (ignore any decimal point digits). This is your north coordinate (place decimals and spaces appropriately).
Now multiply A by 214.868036966.
You will have an 8 digit number (ignore any decimal point digits). This is your west coordinate (place decimals and spaces appropriately).
You can validate your puzzle solution with
certitude.
