A Criterion of Shape Similarity Between Line Segments for Clustering Analysis of Geographical Area Entities

    Abstract
  • A criterion of shape similarity between line segments is presented, which meets rotating invariance and translation invariance. The method is ease in calculation and fit for clustering analysis of geographical area entities. An algorithm of calculating shape similarity between line segments is put forward. The influence of different parameters on criterion results is analyzed.
