Resection is a method for determining an unknown  position (position finding)  measuring angles with respect to known positions.  Measurements can be made with a compass and topographic map (or nautical chart),Mooers Jr., Robert L., Finding Your Way In The Outdoors, Outdoor Life Press (1972), , pp. 129–134Kals, W.S., Practical Navigation, New York: Doubleday & Co.

Position resection and intersection are methods for determining an unknown geographic position (position finding) by measuring angles with respect to known positions. In resection, the one point with unknown coordinates is occupied and sightings are taken to the known points; in intersection, the two points with known coordinates are occupied and sightings are taken to the unknown point. Measurements can be made with a compass and topographic map (or nautical chart),Mooers Jr., Robert L., Finding Your Way In The Outdoors, Outdoor Life Press (1972), , pp. 129–134Kals, W.S., Practical Navigation, New York: Doubleday & Co.
