摘要：Schematization is a quick visualization way to convey graphics information. In cartography, graphic schematization is one aspect of map generalization. This paper analyzes and summarizes the multiple criteria for schematic maps and quantifies these constraints functionally. Based on this, schematic map cartographic generalization framework based on the regular square grid is proposed. Furthermore, we research topological checking methods for schematic maps. Based on these constrains, an effective schematic map is schematized and visualized automatically in a test, while keeping the topological consistency of the network map between original and schematic map
