The article deals with the length differences between georeference surfaces within the state coordinate system of Serbia. It’s an analysis starting from the topography, through geoid and ellipsoid, to the map projection. During the literature review, analyses of the length changes from topography to the state map projection for the geographic territory of Serbia were not found. The set of initial data consists DEM and the geoid model, as well as vector data that contain the boundary of the research area. Calculation will be performed on the basis of 88439 points of grids, located at a distance of 1 km, while the analysis will be done by comparing average deformations, extreme deformation values, percentage of positive and negative values of deformations, as well as percentage of length without deformations. The aim of this research is to provide a set of data on length differences that covers the entire territory of Serbia.
