Altitude problem


Recommended Posts

Have you tried looking it up on the ordnance survey website? If you find the location, you would be able to get a pretty accurate altitude by looking at the nearest contour line. That should be accurate to within 10m at least, and if it is actually on a contour line you should have it dead on.

 

Does that help?

Yup, google earth. Placed me at 72m above sea level, my garmin says about 220ft. So it's not bad as a general guide +/- 10-20 ft.

 

Although you could probably use some long sticks and the sun..... (i'll get me coat)

Excellent. Thanks to all who replied. I should have made it clear that I need this to work globally, not just in the UK. I will trial run it with some of my caches.
