Study on spatial-temporal data dynamic management technology for marine region use
海域使用时空数据动态管理技术研究

The object-oriented approach can express the semantics of what/where/when accurately because of its encapsulation and inheritance. It has become the most efficient way to implement spatial-temporal modeling. Based on object-oriented approach, the Geodatabase data model was expanded and the spatial-temporal data storage structure is studied to achieve history data tracing and marine regions use changing information tracking. These technologies were applied to meet the requirement of marine regions uses management of Xiamen city. The results show that these technological achievements can be used to well solve the problems of history data tracing, change tracking, spatial-temporal relationship calculation and so on. The dynamic management technology is of great importance for marine area management.
