Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. We propose a numerical solution to systems of redundant systems of observation equations. The basic characteristics of this solution are: it is based on a topological, grid-search approach in the Rn space; is suitable for complicated functions deriving from various geodetic observations of deformation monitoring and analysis; it can incorporate weights of observations and compute variance-covariance matrices, i.e. overcome the basic limitations of common numerical solutions. The success of this solution is depicted in the case of the adjustment of a leveling network.
