This post reviews how a line of bearing
and a map can help the hiker determine location. Ideally, a GPS receiver or multiple lines of compass
bearings are used to determine and mark a position on a map. There may be an occasion when there is no GPS
data or only one distant object is available for navigation due to terrain or poor
visibility.
An on-line dictionary defines the word
bearing as:
“….horizontal
direction of one point with respect to another or to the compass.”
Using a compass to take or shoot a bearing is a fundamental
step in compass navigation. It is the
process of sighting on a distant object with a compass and then plotting the
bearing on a map.
In the image below, the woman is sighting her compass (a
Silva Ranger) on a peak in the distance.
