Middle ground

Postby mykalcook » Mon Jan 28, 2019 8:36 am

I really hope this question doesn't cause too much debate.
If Little Ouse is the lowest Trig Point and Ben Nevis is the highest - what would be the most average height?
Is there a consolidated list of heights of TPs?
Any help would be hugely appreciated.
Thanks in advance

Someone may already have this info, but it occurs to me that it should be fairly simple to work out. You can download a gpx file of all trigs (http://trigpointing.uk/trigs/ then click 'download'), then use a service like http://www.gpsvisualizer.com/elevation to add the height data for each point. Then should be fairly simple to load the resulting file into a tool of your choice (Excel can probably do it?) to calculate the average.

Thanks but I'm not looking for the median heights of TPs. My fault for posing the question wrong. I know the highest and the lowest but what is the middle one?
I will follow the links above to see if the answer lies in there but thank you for the info StripyBadger

From my spreadsheet Pillars18.xls

By adding the heights of all known 6590 pillars stations, then dividing that total by 6590, we get:

Average height = 238.163m

This may be slightly out as a small number of pillars were not levelled and the height given on Pillars 18.xls are estimated to the nearest metre from the maps.

Hope this helps.
