  Resection in surveying is also known as free stationing. Is a method of determining a location of one unknown point in relation to known points. The instrument can be freely positioned so that all survey points are at a suitable sight from the instrument. With the instrument are measured bearings (and distances) to at least three known points (in terms of its coordinates) of a control network. Determine the position and orientation of the instrument in relation to where the control network is established.
