运用面向对象方法的方法,对Geodatabase数据模型进行扩展,研究了海域使用时空数据的结构化存储技术,实现了历史数据的回溯和海域使用数据的变化跟踪等功能。结合厦门市海域使用动态管理的需求进行了应用研究,结果表明,Geodatabase扩展数据模型研究成果很好地解决了宗海的历史回溯、变化跟踪、时态关系计算等问题。海域动态管理技术研究对海域管理具有重要意义。
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.
