PP Sewing Thread
Jul 13, 2018

The PP' line refers to the magnetic meridian drawn on a topographic map with a scale greater than 1/100,000. According to the regulations, the right half of the frame is drawn. The magnetic south point on the lower figure is marked with P, and the magnetic north point on the upper figure is marked with P'. The two points are connected by a dotted line, that is, a magnetic meridian, which is called a PP' line. When the terrain icon is used to position, the compass edge and the PP' line are closely combined to make the magnetic needle 0 score. The Earth's magnetic field changes frequently, and the applicable time and variation of the PP' line are placed outside the outline.
