All I needed was a few more inches


Recommended Posts

Once again, a BBC article with one small bit of info missing. What's the datum for the height.

 

3000 ft above what?

 

I don't know the answer, but I bet the original definition was 'above mean sea level'. When they used the GPS was it then calculated for that, or the now more standard WGS84.

 

Incidentally, if sea levels rise, when will TPTB update their definition of mean sea level, and which Munro will drop off the list first?

I'd think the datum measured with would be WGS84, which is worldwide, rather than UK specific.

 

The OS explorer map puts Foinaven at 914m, which is right on the borderline of being a munro (914.4m/3000ft).

(This is of course measured to mean sea level, at Newlyn)

 

A spot height of 915m for Ganu Mor on the OS 1:25000 map was followed by publication of a metric height of 914m at 1:50000 scale. In response to the SMC's enquiry in 1990, the OS confirmed the height as 914m but quoted a range of 913.8-915.2m including measurement error. The midpoint of this range is 914.5m. We have retained 914m in the database but note that a .5 measurement can be rounded up or down.

Last time i heard Foinaven was 2999 ft guess its shrunk a bit

 

The Top Ten Corbetts are:

1. Beinn Dearg 2999 ft 914 m Glen Tromie to Glen Tilt

2. Foinaven 2999 ft 914 m Coigach and Cape Wrath

3. Sgurr 'Choire-bheithe 2995 ft 913 m Glen Etive to Glen Lochy

4. Beinn 'Bhreac 2992 ft 912 m Loch Rannoch to Glen Lyon

5. Leathad an Taobhain 2992 ft 912 m Loch Rannoch to Glen Lyon

6. The Fara 2989 ft 911 m Inveraray to Crianlarich

7. Beinn Dearg Mor 2986 ft 910 m Pitlochry to Braemar and Blairgowrie

8. Meall Buidhe 2986 ft 910 m Strathyre to Strathallan

9. Beinn nan Oighreag 2982 ft 909 m Strathyre to Strathallan

10. Leum Uilleim 2982 ft 909 m Inveraray to Crianlarich

 

As a point of interest cairns and man made structures on top of hills do not count.
