在水文河道地形空间数据库建库过程中，大批量的数据造成了检查矢量化数据的困难，为了高效率完成高程矢量化数据的错误检查与修改工作，设计了“二维系统中数据转化→三维系统中错误检查定位→二维系统中数据修改复查”的流程化数据检查与修改方法。该方法在“长江水文泥沙信息分析管理系统”数据检查中得到了实际应用。该方法不仅适用于GeoView软件矢量化的空间数据库，也可以运用于其他类型的矢量化数据的检查工作。

In the process of construction of spacial database, its necessary to check and correct the errors in the digital map. How to transform the elevation data from 2D systems to 3D systems to check and find out the errors, and then correct them in the 2D systems are presented. The check methods of the elevation data are designed and expatiated. These methods have been used in the data check of Yangtze River hydrologic sediment information analysis - management system. They are not only adapted to the spatial database based on GeoView software, but also adapted to other kinds of vector data.
