Return single resection

The return single resection (measurements are doing from a defined point) is one of modes of theodolitic survey and serves for definition of coordinates of points which can be used in the further as points of a surveying basis or as points which coordinates are necessary for the solution of any other tasks.

It is required to define coordinates of point P (Xp, Yp) if coordinates of points X1, Y1, X2, Y2, X3, Y3 are known and angles b1 and b2 are measured (Example of data input).

Process of calculation of a return single resection is recommended to be constructed as follows:

To enter initial data (the relative location of defined point P and starting points corresponds to figure of the given bookmark.) For calculation with these data to press the Calculate button or Calculate item in the Measurement menu. If necessary, the entered data it is possible to correct and again to press Calculate button.

The coordinates of P point are highlighted on the same bookmark.
