云南省水源地“一张图”矢量数据质检工具的设计与实现

Design and Implementation of a Quality Inspection Tool for Vector Data in Yunnan Province’s “One Map” of Water Sources

摘要: 矢量数据是构建水源地“一张图”的基础，是水源地保护空间管控的依据，其数据质量是提升管理效能的关键。本文基于ArcPy开发设计的水源地矢量数据质检工具箱，能实现一键式质检、数据完整性、空间参考系、范围一致性、逻辑一致性、空间属性和精度检查功能模块。通过实例应用表明，其界面简洁易操作，检查结果准确、满足质检要求，能节约人工质检的人力、财力及时间成本，能为云南省水源地“一张图”构建的矢量数据成果汇交提供质检工具保障。

Abstract: Vector data serves as the foundation for creating a “One map” of water source areas and provides the basis for spatial management and control of water source protection, the quality of this data is key to improving management efficiency. The water source vector data quality inspection toolbox developed and designed in this paper based on ArcPy can achieve one-click quality inspection, data integrity, spatial reference system, range consistency, logical consistency, spatial attributes, and accuracy check functional modules. The practical application demonstrates that its interface is simple and easy to operate, the inspection results are accurate and meet the quality inspection requirements, and it can save labor, financial resources, and time costs for manual quality inspection. It can provide quality inspection tool support for the vector data submission of the “one map” construction of water source areas in Yunnan Province.
