基于多源数据叠加的DLG数据质量检查

Multi-source data superimposed on the DLG data quality check

数据质量检查提供了数字地形图的质量保障,同时,叠加检查是数据质量检查的重要部分,本文介绍了多源数据叠加检查原理,探讨了数据质量自动检查的方法,并对检查结果输出显示。本文开发的检查系统的应用结果表明,文中所述方法正确。

Quality inspection provides quality assurance for the use of digital maps,and the multi-source data superimposed quality check is one important part of data quality check.Lists may exist data of type of error and error variety,recommending multi-source data on the principle of superposition,checking on the data quality automatic inspection methods and showing the output of inspection results.In this paper,the development of the system of inspection results show that the methods described in this paper is correct.
