Abstract

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.

摘要

本文处理塞尔维亚国家坐标系内地理参考表面之间的长度差异。这是从地形开始的分析，通过大地水准面和椭球，再到地图投影。在文献回顾过程中，没有发现对塞尔维亚地理领土从地形到国家地图投影的长度变化的分析。初始数据集包括 DEM 和大地水准面模型，以及包含研究区域边界的矢量数据。以1公里外的88439个网格点为基础进行计算，通过比较平均变形量、极限变形值、变形正负值的百分比以及变形百分比来进行分析。长度不变形。
