摘要
现有的地理信息系统软件一般没有考虑时间因素 ,难以处理时态现象。本文在对多种时态数据模型进行分析 ,对一些时间概念进行讨论之后 ,提出了一种面向对象的时空数据模型并对它的数据结构进行了描述。
Current Geographic Information System(GIS) software does not support manipulation of the temporal data, so it is difficult for current GIS software to deal with temporal phenomenon. This paper raises an object oriented spatio temporal data model and describes its data structure, after analyses the shortcomings existing in the traditional data model and discusses the conception of time in GIS
