Compass navigation in conjunction with a map ("terrain association") requires a different method. To take a map bearing or "true bearing" (a bearing taken in reference to true, not magnetic north) to a destination with a protractor compass, the edge of the compass is placed on the map so that it connects the current location with the desired destination (some sources recommend physically drawing a line). The orienting lines in the base of the compass dial are then rotated to align with actual or true north by aligning them with a marked line of longitude (or the vertical margin of the map), ignoring the compass needle entirely. The resulting "true bearing" or map bearing may then be read at the degree indicator or direction-of-travel (DOT) line, which may be followed as an "azimuth" (course) to the destination. If a "magnetic" north bearing or "compass bearing" is desired, the compass must be adjusted by the amount of magnetic declination before using the bearing so that both map and compass are in agreement. In the given example, the large mountain in the second photo was selected as the target destination on the map. Some compasses allow the scale to be adjusted to compensate for the local magnetic declination; if adjusted correctly, the compass will give the true bearing instead of the magnetic bearing.
