AUTOMATIC CORRECTION ALGORITHM OF HYFROLOGY FEATURE ATTRIBUTE IN NATIONAL GEOGRAPHIC CENSUS

Li, C.; Guo, P.; Liu, X.

A subset of the attributes of hydrologic features data in national geographic census are not clear, the current solution to this problem was through manual filling which is inefficient and liable to mistakes. So this paper proposes an automatic correction algorithm of hydrologic features attribute. Based on the analysis of the structure characteristics and topological relation, we put forward three basic principles of correction which include network proximity, structure robustness and topology ductility. Based on the WJ-III map workstation, we realize the automatic correction of hydrologic features. Finally, practical data is used to validate the method. The results show that our method is highly reasonable and efficient.
