Diagram Of True North. This diagram also provides the declination between true north and the orientation of the universal transverse mercator utm grid north indicated by the gn symbol. G refers to grid declination.
Therefore if you use declination from a canadianaustralian style declination diagram be sure to take bearings to and from the map by making the meridian lines on the compass. The line showing the. Some maps especially very old maps do not have this diagram.
Draw a polar diagram showing true north at 0 degrees azimuth 12 oclock.
The true bearing to a point is the angle measured in degrees in a clockwise direction from the north line. Some maps especially very old maps do not have this diagram. On the map the true north runs on the longitude line. This diagram also provides the declination between true north and the orientation of the universal transverse mercator utm grid north indicated by the gn symbol.
