Reply to "Elevations from various sources"

I agree with Pete.

But I think if we are asking the records people to accept our drop values at face value then we should require that those drop values use elevations directly from USGS data anytime the google earth drop calculation ends up between 0.5 and 1.5 m/km. At least we have some information telling us how accurate the USGS data is. We have next to nothing telling us how accurate GE elevation data is.

This is not asking much. I would guess the drop ends up between 0.5 and 1.5 about 5% of the time, and looking up the elevations with the link that Justin provided is very easy and very straight-forward. It's a lot less work than what folks had to do before GE was available.
