Identifying Real Transport Networks in Rural Areas on the Basis of Cadastral Data

摘要

This article presents a comprehensive solution allowing the identification of approximate real transport networks in rural areas. It is based on the use of cadastral databases for the purpose of building a model of the area in question as well as graph algorithms identifying the shortest paths in the graph. The proposed algorithm of route calculation works well also in areas with extremely unfavorable fragmentation indices and in areas where plots have no direct access to the road network. The efficiency of the algorithm was tested on large objects. It was also used in the process of building a comprehensive system that implements and evaluates the effects of consolidation works. The results are of significance in the process of analyzing land fragmentation. They indicate the possibility of replacing simplified indices, which utilize rectilinear distances, with indices based on the precise values of the actual shape of transportation network.
