Why do you need more than one tool, and why are you interested to know the coordinates in 6 decimals when you're travelling? Personally, I find Google Maps on my smartphone or my Tom-Tom perfectly satisfying.
I have seen this kind of tool while I was searching on browser. It happens when I was on ride, I don't know where I am then I saw this website where-am-i.today and it gives my location, not just accurate but the coordinates are the most interesting. Any tools similar that you may suggest on me?
