| 摘 要： | 针对目前海战场信息系统的不足,引入时空数据技术对战场数据建模,并支持设计了海战场时空数据库原型系统.对系统要求的时空查询问题进行归纳,结合海战场数据特性加以分析,为后续的索引建立提供了依据.3D R-tree相较现有的其他时空索引更适用于海战场的环境,并通过扩充部分的弥补了其检索效率的不足.

| Abstract: | Directed against the defect of naval information systems at present,spatio-temporal data model on the naval battlefield is constructed and support designing the prototype system of STDBMS-NB.Spatio-temporal query problems in demand of the system are concluded and the featue of the naval battlefield is studied,which provides basis of spatio-temporal index-building.3D R-tree adapts the environment of the naval battlefield more than other spatio-temporal indexes after its augment has improved research efficien... |
