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.
The Texas Land Survey System is often measured in Spanish Customary Units. The most important of these is the vara, which, while ambiguous in the past, was legally established to be exactly 33 + 1 ⁄ 3 inches (846.67 mm) long in June 1919. [2] The subdivision levels in Texas are as follows: [3]

The intersection of these lines is the current position of the vessel. Usually, a fix is where two or more position lines intersect at any given time. If three position lines can be obtained, the resulting "cocked hat", where the three lines do not intersect at the same point, but create a triangle, gives the navigator an indication of the ...
