摘　　要：空间地理数据由于内容和来源的差异导致数据之间转换十分困难,而基于不同空间数据模型、不同软件平台的数据,由于通常都具有各自的数据标准和数据格式,并且软件平台相对独立而封闭,因此,也无法直接进行系统之间的数据共享。本文对GML的空间信息表达和时空拓扑分析进行研究,将GML技术与时空表达相融合,并以地籍信息管理为例,将GML应用在地籍数据建模上,对于数据的交换与传输、共享与集成都是一种新的尝试。The spatial geographical data caused by the differences in content and the source of the conversion between the data is ex-tremely difficult, and the type of data based on different spatial data models or software platforms which is independent relatively and closed usually have their own standard and format, therefore can not directly have a sharing between systems.This paper researches on the expression of spatial information and spatio temporal topology analysis.It integrates GML technology with spatial expression and applies GML in cadastral data modeling taking cadastral information management as an example.It’ s a new attempt in data exchan-ging, transmitting, sharing and collecting.
