Least-squares adjustment of triangles and quadrilaterals in which all angles and distances are observed.
The solutions for combined triangulation-trilateration least-squares adjustment of triangles and quadrilaterals, in which all angles and distances are observed, are developed. The triangle is adjusted by the method of observations only, and the quadrilateral is adjusted by the method of indirect observations. The problem of choosing the proper weight factor relating the angle measurements to the d
