The directional software packages will at minimum handle UTM and Lambert conformal conic convergence. Always align this line with the vertical lines on a map (Figure 6-9). Web(1) Look at the declination diagram and determine the direction between the line representing grid north and the line representing magnetic north. b. TO CONVERT A GRID AZIMUTH TO A MAGNETIC There are two methods of intersection: the map and compass method and the straightedge method (Figures 6-16 and 6-17). yg! $RC ku,B:d k5(*(ig0;5o!` QuM^4oG-9Q[bG}1g_iulBewm|J""F]||0 This method can be used at night. The back azimuth of 180 degrees may be stated as 0degrees or 360 degrees. In this example, the known azimuth is 270 magnetic. (f) The inclusion of the true-north prong in relationship to the conversion is of little importance. Azimuth in Surveying 2 0 obj To convert a magnetic azimuth to a grid azimuth, subtract the G-M Angle. (5) Convert the grid azimuth to a back azimuth. Magnetic When using an azimuth, the point from which the azimuth originates is the center of an imaginary circle (Figure 6-2). To convert a grid azimuth to a magnetic azimuth, add the G-M angle. (4) Convert the magnetic azimuth to a grid azimuth. YMMV. words, an object moved in the direction of 223 degrees (Southwest All of them divide the circle into units of angular measure, and each has a scale around the outer edge and an index mark. Web1995 G-M ANGLE MILS) 5040 TO CONVERT A MAGNETIC AZIMUTH TOA GRID AZIMUTH ADD G-M ANGLE 0-95 ro GIVE A STANDARD REFERENCE ON THIS SHEET TO NEAREST 100 METERS tifying 100,000 meter point lies: ICAL grid line to LEFT LARGE figures labeling e top or bottom margin. (2) To plot an azimuth from a known point on a map (Figure 6-7), (a) Convert the azimuth from magnetic to grid, if necessary. The graphic below demonstrates for both East & West Declination.
