Abstract

In the case that more constraints than necessary to remove the network datum defect< have been
defmed, a new type of geodetic network will be obtained " over - constrained geodetic network ". Datum changes may be obtained by Similarity Transformations in order to select the proper
coordinate datum for geodetic networks as well as to analyse the stability of the reference points.
The purpose of this research paper is to choose the optimal fixed points for over - constrained
geodetic networks by using Similarity Transformation. A numerical example is presented.
