| 摘 要： | 由离散水深数据如何描述海底地貌以及水深数据与属性数据如何关联一直是海洋地理信息系统(MGIS)需要解决的问题。文中探讨利用超图中层次结构和非层次关系对海底山峰构建,最后在一个试验区内实现,论证了其可行性。

| Abstract: | The problems on how to describe submarine configuration by discrete bathymetric data and correlate bathymetric data and feature data are basic ones that need to be solved methodically in MGIS.It tries to approach these two problems' resolution-generating submarine peaks by using hierarchical structure and nonhierarchical relation in hypergraph,at last realizing it in a test area.By doing these it proves that hypergraph is a workable method for solving these problems. |
