If it is not, then you were plotting in the wrong grid. Ignore the noise. To express direction as a unit of angular measure, there must be a starting point or zero measure and a point of reference These two points designate the base or reference line. The width of your fist will approximately be 10 degrees. The most commonly used are magnetic and grid. There are two methods of intersection: the map and compass method and the straightedge method (Figures 6-16 and 6-17).

For your convenience, you can use a UTM Universal Transverse Mercator AKA USGS 7.5 minute map. Align a protractor (left drawing) or the N-S or E-W directional axis of a compass (right drawing) with the map's border and read the bearing in degrees toward the direction of the destination. Azimuth determines which direction to take, while Elevation determines how high up in the sky you should look. (5) Repeat 3 and 4 using a second known position. If youre not certain of your exact location but are located on a linear terrain feature such as a road, creek or along a similar body of water, this can pinpoint your position. Basically, once you determine what your Magnetic Declination is, you simply use the provided tool, adjust the declination reading to correspond with that number (either East or West) and use your compass on the map as well as when shooting your azimuth. There are three base lines true north, magnetic north, and grid north. Using the edge of your protractor, draw a straight pencil line between points A and B. (6) Repeat 3, 4, and 5 for a second position and a third position, if desired. The declination diagram is used for these conversions. When using the protractor, the base line is always oriented parallel to a north-south grid line. When using the straightedge method (Figure 6-19).

PDF Survival-Training Orientierung - How To Find Your Way - Wildnisschule Lupus (b) From the base of the grid-north line (prong), draw an arbitrary line (or any azimuth line) at a roughly right angle to north, regardless of the actual value of the azimuth in degrees (Figure 6-9). No special azimuth formula is needed, just a map, protractor, pencil and your start and end points. 5-29). In either case, the listed Declination, or GM Angle on the map (which may or may not be correct due to Magnetic North Pole movement) is for the center of the map, and depending on the whats under or on top of the surface, the Declination degree may be distorted during your trip. Back azimuths are calculated as follows: If the original azimuth is less than 180 degrees you ADD 180 degrees to the original azimuth, thus an azimuth of 45 degrees (<180) will have a back azimuth of 225 degrees.
