| 摘 要： | 本文提出了一种适于表达三维地籍的空间拓扑数据模型,并分别在概念层次和实现层次给出了概念模型和逻辑模型。概念模型分为3层:要素层、几何层和拓扑层。要素层用于表述地籍管理对象,几何层用于描述实体的几何形态,拓扑层用于表达实体间的拓扑关系。在概念模型基础上,给出了对应的逻辑模型。实验结果表明:所提出的模型有效、可行。

| Abstract: | The paper analyzed modeling needs of 3D cadastre,proposed a spatial topological data model which is suitable for representing 3D cadastre,presented the conceptual model and logical model from conceptual level and implemented level separately.The conceptual model could be divided into three layers: feature layer,geometry layer and topology layer.The feature layer was used to represent objects of cadastral management.Geometry layer was used to describe geometrical shapes of entities and topological relations between entities were saved by topology layer.Based the conceptual model,the paper gave corresponding logical model.Experiments showed that the proposed model was effective and feasible. |
