摘要
传统的基于专题地理分层的GIS数据模型在数据组织 ,数据共享及复杂的空间分析方面存在明显的不足 ,认为发展新一代的基于特征的时空模型成为必然。本文结合实践中地籍变更的特点 ,提出了基于特征变化状态的时空数据模型。该模型保持了地理现象的完整性 ,实现了时空专题信息的有机集成 ,有利于发展复杂的面向目标的定向分析。
Traditional theme map layer GIS model are deficient in data organizing, data sharing and complex spatial analysis.It is set forward that developing features based on spatio-temporal data model is inevitable.This paper sets forward a new spatio-temporal data model based on the states of the changing features according to the character of land registration change.This model can sever for integrating geographic phenomena and geographic information as well as applying object-oriented analysis method.
