摘　　要：为了提高基础地理信息数据的生产与质量检查效率,本文以1∶10000数字线划图数据为例,设计了基于图论的DLG数据接边检查算法,并通过编写程序实现了自动接边检查工具,主要包括几何位置检查、要素属性检查。以某地4幅1∶10000 DLG数据进行接边检查试验,试验结果表明:本文设计与实现接边检查工具能够快速定位与识别接边错误位置、错误类别,在准确率与效率方面均优于人工检查方法与基于ArcEngine的检查方法,具有较高的适用性,能够有效确保1∶10000 DLG数据的质量,具有积极的推广与应用价值。In order to improve the production and quality inspection efficiency of basic geographic information data,1∶10000 digital line graph(DLG)data is taken as an example in this article to have a DLG data edge inspection algorithm designed based on graph theory and an automatic edge inspection tool implemented through programming,which mainly include geometric position inspection and feature attribute inspection.The edge inspection experiment was conducted by using four 1∶10000 DLG data from a certain location.The experimental results show that the designed and implemented edge inspection tool in this paper can quickly locate and identify the location and category of edge errors.It is superior to manual inspection methods in accuracy and efficiency and inspection ones based on ArcEngine and of high applicability.It can effectively ensure the quality of 1∶10000 DLG data,and has positive promotion and application value.
