Overwrite the default numbers in the blue boxes below with the latitude or longitude of your location. To calculate azimuths about a traverse, it is necessary to obtain the back azimuth of a line. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, This question appears to be off-topic because it is actually about basic mathematics. There are several conventions for azimuths ("geological", "geohraphical" - clockwise, anticlockwise). They are usually measured from the north and vary from 0 to 360 and so they do not require letters to categorize their quadrant. These are the imaginary lines that go around and from pole to pole on a globe, respectively. You will then be able to use the line that joins the two markers to help you identify which direction you need to look in to see your object. Similarly, 180 is south, and 270 is west. When bearings are measured with reference to true meridian it is called as true bearing. Ninety degrees corresponds to east, 180 degrees is south, 270 degrees is west, and 360 degrees and 0 degrees mark north. National Geodetic Survey have used south as its reference direction for The North American Datum (NAD) of 1927 and north as the reference direction for NAD-1983. To convert from degrees with decimal minutes to decimal degrees shortens the formula: Converting in the opposite direction is slightly harder. But don't worry. The program retrieves the current date and time from your computer, and fills North is defined to have an azimuth of 0 and south has an azimuth of 180. What 4 formulas are used for the Bearing Calculator? This means, for example, that an azimuth of 180 means due south. If true north is used as reference, it is represented by an azimuth of 0, and angle values increase towards the east. Here, in case of azimuth, the value of forward azimuth and backward azimuth will be different. Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? Example: The azimuth of the sun at 165 degrees: it is around 11 am. The azimuth of a line is defined as the horizontal angle, measured clockwise, from a base direction to the given line.
