Comparison of Squared M-split Method Vs. Absolute M-split Method ‐ Case Study
In this paper we analyse and compare two modern methods of deformation analysis: the squared Msplit method and the absolute Msplit method. The comparison is made on cases of simulated and actually measured horizontal geodetic networks. The squared Msplit method is based on the assumptions of the least square method, while the absolute Msplit method is based on the assumptions of the least absolute deviation method. For each method, we developed a computer programme and used it to calculate point displacements in both a simulated and a measured 2D geodetic network. The purpose of this article is to compare the displacements. The results of the two methods differ by up to about one centimetre in the simulated network and by less than two centimetres in the actually measured geodetic network.
