Abstract:
The suggested method enables us to improve the accuracy of city planning data by matching it with exact cadastral data. The existing approaches do not work well in the case of partial equality of polygon boundaries. The main idea of the presented algorithm in this paper is based on defining correspondent segments of polygon boundaries and further replacing polygon boundary segments of the non-accurate layer by segments of the accurate data set, segments without pairs are rectified using ground control points. The resulting data contain parts of the accurate data set polygon boundaries, whereas the remaining elements are rectified according to the replaced boundary segments. A review implemented by specialists enables us to say, that the results are satisfactory.
