Least Squares Adjustment of Triangulation Net between Geodetic Stations
Local triangulation nets, both urban and rural, can be precisely adjusted to large-scale geodetic triangulation control with comparatively little effort if all the angle, distance, and azimuth relations involved are reduced to simultaneous equations expressed in terms of direction corrections and then adjusted by least squares methods. The derivation of the correction equations is illustrated by a sample net containing three quadrilaterals. Application of the method is also illustrated by adjustment of a local net for Logan County, Ohio.
