Abstract

The paper introduces the edge matching method of vector data on the basis of the arbitrary polygon domain. The method contains three steps: (1) the edge matching features district is divided into source features and target features in terms of the edge matching domain; (2) logical edge matching; (3) the automatic combination of attribute fields while physical edge matching. Test analysis indicated that the method of edge matching extends the mapsheet domain of edge matching to arbitrary polygon domain. The edge buffer search reduces the searched data, which greatly increases the search efficiency, and consequently improves the edge matching efficiency and the accuracy rate. The advantages and the procedure of the programs will be elaborated in the paper.
