Hi tiompan,

Another day, another question! I just saw your answer to a proposal concerning Chun Quoit on another forum and I was wondering how to calculate that 60m distance from the line. Probably some elementary thing that I should remember from school.

There's something around here that I spotted some time back and never got around to going back to the figures to check properly. Perhaps over the Christmas.

Thanks,
Gordon.

Hi Gordon , rather than calculate you could also work it out using Google Earth ,drawing a line between the two angles then measuring the distances or similarly mark the points in gpsu and measure again .

Should have mentioned it might be dificult to work it out in GE if the sites are in Ireland due to lack of hi res unless you have precise co-ordinates ion which case the background fuzziness won't matter .
