| 摘 要： | 空间数据是GIS的基础内容,数据的质量控制是GIS生存和发展的保证。本文就GIS与其它信息系统的不同点,从空间数据的内容与基本特征出发,分析了空间数据的质量标准,提出了按其三个基本特征的范畴实施质量控制,并对空间数据进行了质量评价,从而达到了GIS空间数据质量控制的目的。

| Abstract: | Spatial data is the basic contents of GIS,and the quality of it is the guarantee of survival and development for GIS.Based on the individual character between GIS and other information system,and started from the contents and basic character of spatial data,this paper analyze the quality standard of spatial data,and present a way to spatial data quality control from its three basic character.By evaluating its quality in every step in the whole process,the purpose of controlling the spatial data can be obtai... |
