  • 摘要:

    Elimination of displacement due to map editing inherent in road centerline data of the New Topographic map Information System (NTIS) is implemented. Panchromatic satellite images from ALOS/PRISM are used in the process. Histogram analysis of gray value profiles parallel to the roads is employed. The true-position candidate is selected by supervised classification of histograms using support vector machine (SVM) method. According to the experiments with the Japanese NTIS road centerline database, the proposed method reverses the displacement of approximately 50% of the road features, while a further 20% of the road features are validated as already located at the true position. The proposed method is proved to be useful for German Amtliches Topographisch-Kartographisches Informationssystem (ATKIS) road database. This indicates wider applicability of this method to various geographic regions.
