I'm still relatively new to this game but as I understand it the only reason why weather, Notams etc. are in this abbreviated format is because they used to be faxed through. Given we are in the days of computers now can't they just plot the points on a map of the UK and if it seems you are going near the area then you can read the exact poisition from the NOTAM. I seem to remember that Farnbourough fo something like this during the airshow when the actual zones they create are quite complex when written on the NOTAM.
