Document Summary
Orient a map means to determine how directions on the map align to directions on the ground. Before maps were drawn with china on top, but now made using true north at the top. Inspection method: easiest ways to orient map inspection method, with this technique, do not need to know which way north is, no need of tools. Must be able to see one or more linear features or prominent objects in your vicinity. Must be able to identify the same features on the map: one linea feature. Position yourself on a linear feature shown on the map, such as a road. Then turn the map until mapped feature lines up with the real on in front of you. The line you see between you and the features is called sight line. 2nd method is to assume a position that lies on a straight-line extension of the ground feature.
