Question

Let's say you plan to hike from the bench mark in section 9 to the small knob near the mouth of Bob Creek in section 33 (marked with x's). From your map, you can tell that your destination is on a map bearing of N14W. Let's say that you then lose your map, and need to hike that distance on a monnless night. You remember the bearing, and you have your compass, so you head off. How far off (in miles), and in which direction, from that destination would you end up if you used that compass but made no correction for magnetic declination?

Explanation / Answer

Distance can be calculate by the string method with the application of scale unit. U need to have the physical map and by the help of strings u can simply measure and distance on the map and find the corresponding distance on earth surface using the scale provided.

Here in this case , the scale given is 1:24000 i.e 1cm on the map here means 24000 cms on the ground.

Now , normally with the help of compass , the navigation is possible and even if we dont have a map we can reach our destination. But if there is some corrections to be made regarding the magnetic declination , the hikers should have considered this and not omitted unless they want to end up reaching a different place to what they would have thought off in the beginning.

There are several adjustments that we need to make in compass inorder to get accurate reading-

From secttion 9 to section 33 near the creek - the hikers would be left in the direction of NW from the initail point of view. There would be an approx difference of 1.7-2.0M.
