Comparative analysis of length differences between georeference surfaces

Abstract

The article deals with the length differences between georeferencesurfaces within the state coordinate system of Serbia. It’s ananalysis starting from the topography, through geoid and ellipsoid,to the map projection. During the literature review, analysesof the length changes from topography to the state map projectionfor the geographic territory of Serbia were not found. Theset of initial data consists DEM and the geoid model, as well asvector data that contain the boundary of the research area.Calculation will be performed on the basis of 88439 points ofgrids, located at a distance of 1 km, while the analysis will bedone by comparing average deformations, extreme deformationvalues, percentage of positive and negative values of deformations,as well as percentage of length without deformations. Theaim of this research is to provide a set of data on length differencesthat covers the entire territory of Serbia.
