Question
good day,



i am having trouble understanding the conversion of bearing to azimuth and azimuth to bearing. i am an idependent study student working on a capstone project. any explanation of the conversion process would be greatly appreciated.



i want to convert the following bearings to azimuths using north as a reference: N23°W, N90°E, N13.2°E, S11.98°W, N17°S, S11°W, and S79.89°E.



i also want to convert the following bearings to azimuths using south as a reference: N23°W, N90°E, N13.2°E, S11.98°W, N17°S, S11°W, and S79.89°E



i also want to convert the following azimuths to bearings using north as a reference: 15.6°, 25.9°, 98.8°, 325.47°, 5°, 68.7°, and 55.9°.



i also want to convert the following azimuths to bearings using south as a reference: 15.6°, 25.9°, 98.8°, 325.47°, 5°, 68.7°, and 55.9°.



and finally i want to find the statue miles with these longitudes  : 15.6°, 25.9°, 48.8°, 25.47°, 5°, 68.7°, and 55.9°.



thank you much,

jason


Answer
This should be quite easy, see http://academic.brooklyn.cuny.edu/geology/leveson/core/linksa/comp.html

for a reference. The azimuth just tells you were on the compass you are, starting at 0 degrees for north and going counterclockwise. So due West is 270 degrees, etc..

The bearing just tells you "start at North (or South) and go some number of degrees east or west".

I will do a couple of them for you:

N23W means go 23 degrees west from north so you will come to 333 degrees.

15.6 degrees would be either N15.6E or S164.4E

I don't understand  your last question about finding statute miles of a certain longitude, what does that even mean?

Perhaps:

will have what you need.
