Finding grid azimuth
WebGrid bearing of survey line is clockwise angle from grid north and similarly clockwise angle from magnetic north is Magnetic bearing. Azimuth can be obtained by astronomical observations (tedious) or can be computed by latitude and longitude (spherical coordinates and spherical trigonometry). Webb. Plot grid azimuths from known points to the unknown point on the map. (1) Mark your position (the observers) on the map. (2) Determine the magnetic azimuth from your position to the unknown point. (3) Convert the magnetic azimuth to a grid azimuth. (4) Place the index point of a protractor on your plotted position.

WebThis is the opposite direction of an azimuth. It is comparable to doing an "about face." To obtain a back azimuth from an azimuth, add 180° if the azimuth is 180° or less; subtract 180° if the azimuth is 180° or more. The back azimuth of 180° may be stated as 0° or 360°. Examples: LAMS.
