Re: [Talk-us] Incorrect Summit Elevations - Colorado

I somewhat glibly asked what should the height spec be and I think the answer should be orthometric heights based on WGS84 and the current associated geoid model. When converting to feet there is the wrinkle of US survey feet vs the international foot. This matters in state plane systems, but
