| Abstract: | The data of land source researched are diatinct scale vector maps. Based on the land-use data, the paper discusses the arithmetic applied and realized of Delaunay triangle networks applying in polygons generalization and punctate objects generalization of land data type, describes the realized progress and the exprerimentation result of the two arithmetics. The paper also analyzes and compares the several arithmetics of applying in punctate objects and introduces the realized progress. Compared the polygons generalization, the paper emphasizes the general thinking and the realying. In the end, the paper validates the feasibility with the example of the system of the intellectualizing and automatism synthesis of the land use data base. |
