The research introduces a new mathematical model for computing the position of points in space
(X, Y, Z) by the intersection of inclined angles derived from the measured horizontal and vertical
angles using spherical trigonometry principles with the aid of the conventional surveying instrument
(Theodolite), The most probable value (m.p.v) of the position of a point should be computed by the
method of ieast squares when the redundancy in observations exists and then it provides us with the
precision indices for the computed coordinates.
