'''ResectionPosition resection and intersection''' isare a methodmethods for determining an unknown [[geographic position]] ([[geopositioning|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]]),<ref>Mooers Jr., Robert L., ''Finding Your Way In The Outdoors'', Outdoor Life Press (1972), {{ISBN|0-943822-41-6}}, pp. 129&ndash;134</ref><ref>Kals, W.S., ''Practical Navigation'', New York: Doubleday & Co.
