| Abstract: | Division of census district is an import step in population census,which costs a lot of man power,finance and resource.Based on the theory and technology of Delannay triangulation dividing,the census district is automatically divided with line feature as constraint condition.The paper introduced the characteristic of Delaunay triangulation,discussed the technologies,measures and processes of census district division.The application example was given finally. |
