A celestial body due north, for example, has an azimuth of 0 degrees, one due East 90 degrees, one due South 180 degrees, and one due West 270 degrees. Now, if you want to convert a MAZ to GAZ using the example above (in that you have a MAZ of 180, simply add the 15 degrees declination to the 180, and you have a correct GAZ. You are facing North if you stand in front of the compass and rotate your entire body with the compass until the North part is directly away from you. If youre not using that type of compass, youll always have both Grid and Magnetic Azimuths to deal with when navigating. The user should be able to determine whether the initial azimuth reading was correct. Figure 6-16. 2. Intersection, using a straightedge. On medium-scale maps, the declination information is shown by a note in the map margin. For greater accuracy, the desired method of resection would be to use three or more well-defined locations. How do you plot a grid azimuth? - Short-Fact Determine the value of the angle (grid azimuth) from the scale. It also may be convenient to construct a G-M angle conversion table on the margin of the map. Determine the grid coordinates to the desired accuracy (Figure 6-17). (b) Place the index of the protractor at the point where the drawn line crosses a vertical (north-south) grid line. The intersection of the lines is your location. These data are shown in the form of a grid-convergence note. At the end of this course, you will be able to determine grid Azimuth using a Protractor. Figure 071-COM-0018 1.
