摘要
详细论述了地图数据及其空间关系、地图数据的几何与属性的关系以及地图要素空间关系的建立与地图要素完整性之间的关系。提出了解决由于地图要素分层管理所带来空间关系分割问题和多图幅之间空间关系连接的方法。最后给出了基于地图数据空间关系的数据模型。
This paper mainly discusses map data and it's spatical relation, the relation of geometric element and attribute elemetn, the relation of building map element spatial relation and integrity of the map element. This paper prefers a method to solve spatial relation segmentation and spatial relation connection of numbers of topographical maps. At last, This paper prefers a data model based on map data spatical relation.
