| 摘 要： | 引入面向对象时空数据模型 ,把各种实体作为对象 ,把道路作为面状要素描述。作为面状要素的道路对象直接继承原有道路的非空间特征 ,通过道路中心线对象和交点对象来继承原有线状要素的道路特征 ,包括网络关系 ,叠加关系等 ,通过车道段对象来增加作为面状要素的道路特征。

| Abstract: | An object_oriented spatio_temporal data model was introduced,and all real things were treated as objects and road was described as face shape element. Road object as face shape element inherited non_spatial feature of road directly, inherited the feature of road that is viewed as line shape element by road_center_line objects and intersection_point objects, added the feature of road that is viewed face shape element. |
