海战场时空关系研究

The Research of Spatio-temporal Relationship on the Naval Battlefield

时空关系是时空数据模型中体现时空语义的重要部分,在海战场时空数据模型整体框架中起着重要的作用。根据海战场数据特点对现有空间、时态关系表达方式进行了遴选分析并修改补充,建立了完整的海战场时空关系表达方式,着重论述了海战场时空拓扑关系的表达。在此基础上,分析了海战场时空关系的应用情景,提出了适于海战场时空关系的表达运算。

Spatio-temporal relationship is very important to spatio-temporal semantic expression in spatio-temporal data model and it takes an significant part in the whole frame of spatio-temporal data model on the naval battlefield.Current expressions of spatial relation and temporal relation analyzed based on the feature of the naval battlefield, complete spatio-temporal relation-expressing on the naval battlefield is established.On this foundation,the situation on which spatio-temporal relationship on the naval battlefield applies is analyzed and the expression of spatio-temporal relation-operation is projected.
