Finding Bearings.
19 Answers
Could anyone point me at a site where I can work out compass bearings? I have a number and I'm asked to find a bearing of, followed by a longer number. The last number is a degree number. At the moment I haven't been given a point from where these numbers are to be worked out from but by the time I get them I'm hoping for a site so I can try to learn how to do it.
I hope all that makes sense.

Er, sorry, no!
To work out a compass bearing you need to know how far east (or west) of a starting point the end point is, and how far north (or south of it). Then it's just simple trigonometry (as long as the two locations aren't so far apart that the curvature of the Earth has to be considered as well). Perhaps the numbers you've been supplied with are OS grid references?

So that tells us that you need to start at an unspecified point, face North, turn clockwise through 294.59865502219 degrees and then travel 2.104831 kilometres (or possibly miles, nautical miles or something else, since the units aren't specified).
However I can't see why anyone would need to give a bearing to an accuracy of one-hundred-billionth of one degree, nor to give a distance to an accuracy of 1mm (assuming that the units in your information are in kilometres).
Your username seems particularly appropriate here ;-)

Thanks Buenchico, very nice of you to say so ;). Anyway, I can only give you the numbers I have been given, but as my original question was, does anyone know of a site that would help, maybe all these numbers would then make sense to me! And yes my username is very apt, and not just with this question!

The possibility of geocaching came into my mind too. (There seem to be some very strange clues used by geocachers!)
However I can't see that any particular website would be of use to you, as I've already done everything that can can be done with those figures without further information being provided.
Sorry :(

The starting point is on a bridleway just north of Hadrian's Wall near Heddon-on-the-Wall. On the specified bearing, 2.1 km would be at the corner of a lane with public access north of a farm called 'Whitchester', so geocaches look quite probable. 2.1 miles is inside the perimeter of the disused Ouston Airfield, so seems less likely.
Strange, the brackets must have stopped the link from being shown as such:
