WebModified resection is the method of locating one's position on the map when the person is located on a linear feature on the ground, such as a road, canal, or stream (Figure 6-20). Proceed as follows: a. Orient the map using a compass or by terrain association. b. Find a distant point that can be identified on the ground and on the map. WebDraw a pencil line along the edge of the compass. You now know you are somewhere along that line--a line of position. Repeat steps 1 through 4 for the second bearing to the second feature in the field. Your position is at or at least close to the point of intersection of the two lines you drew on the map.
