利用CASS SME实现GIS数据质量检查的方法研究

Research on the Method of GIS Data Quality Check Using CASS SME

从分析数据加工中的错误来源入手,在研究数据特性的基础上,介绍了利用SME软件进行基础地理信息数据质量检查的方法,具体阐述了房屋要素和其他要素穿越检查方案的编写过程,利用真实数据检验编写的检查方案,从运行结果看,利用南方CASS SME质检模块进行数据质量检查的方法是可行的,结果是正确的。

This paper analyzes the data processing errors, and introduces a method of checking the quality of geo- graphic information data by using SME software based on data characteristics. And spatial addressed tile preparation process of the data check program about huilding features intersect other features. Finally,this paper proves it is feasible and correct that we perform data quality eheeks using South CASS SME module
