Over the years, I've had a blast solving the virtual globetrotter puzzles by t4e & dfx. With their permission, I thought that I would add to the series.
To obtain the final coordinates, your first job will to be to find out the city where this picture was taken. After you have this information, convert each letter in the city name to its corresponding numerical value (ie. A=1, B=2, etc). Any reference to first, second, third etc. means the full numeric value of the letter in that position.
Add to posted North: (2nd*3rd) + (5th*4th)
Subtract from posted West: (6th*8th) + (4th*6th)
