Abstract

Abstract: As an important component of land use map generalization, the comprehensive quality of linear features has great significance to improve the accuracy of automatic cartographic generalization. So based on the theory of fuzzy comprehensive evaluation, quality evaluation of comprehensive linear features in land use map will be studied in this paper. First of all, evaluation indicators,which include geometric factors, topological factors, structural factors and gestalt factors are chose using method of cartographic generalization constraints. Secondly, evaluation rank and weight set are confirmed, and then a quality evaluation model of comprehensive linear features will be built. At last, the validity of the evaluation method will be verified by experiment. It is concluded that the quality evaluation model in this paper can be provided a new thought for evaluating generalization quality of linear features in land use map.

Key words: map generalization, land use map, linear features, quality evaluation, fuzzy comprehensive evaluation
