Deformation analysis of a geodetic monitoring network

Setan, Halim and Singh, Ranjit (2001) Deformation analysis of a geodetic monitoring network. Geomatica, 55 (3).



Results of deformation analysis are directly relevant to the safety of human life. Therefore one has to be very careful in assessing the data of a monitoring network to avoid wrong interpretation of the displacements. This paper presents a deformation analysis procedure that consists of network adjustment of individual epochs, trend analysis of the displacement field and modelling of the deformation. During trend analysis, two robust methods and a non-robust method have been adopted and applied in determining the trend of movements for all the common points in a monitoring network. The trend of movements then form a basis for preliminary identification of the deformation models. The developed procedure has been implemented in a program package known as NETDEFAN (NETwork and DEFormation ANalysis). A numerical example is also given by using known data of a dam monitoring network.
