The relative accuracy might be closer to correct than the absolute accuracy, provided you're using the same unit to measure both the saddle and the summit (i.e. both could be close to 50' off in the same vertical direction), so it still might give some clues as to the prominence of a peak. But definitely not definitive.Trotter wrote: ↑Tue Oct 26, 2021 2:34 pmYeah I'm leaving that one behind. Soon it will cease to be ranked, or even a 13er I bet.bergsteigen wrote: ↑Tue Oct 26, 2021 1:58 pm Top of my list for demoted peaks is Bartlett. Please please! I know it will happen eventually.
Sidenote, for anyone using true GPS to measure saddle or summit altitudes, I think most ones have a vertical accuracy of like +-50 feet. Not super crazy precise
If your GPS can record RINEX and you're able to post-process it, then that's even more accurate than otherwise. But yes, generally GPS vertical elevations are not the most trustworthy.
