摘要
为保证GIS空间数据表达的准确度、精度,数据组织的完整性、规范性、统一性,数据应用的可行性等,必须对数据进行质量检查。对GIS空间数据误差来源、检查方法、检查流程进行探讨,并开发了数据质量检查模块,对实验数据进行了质量检查,实验结果表明数据质量检查方法可行。
In order to ensure the accuracy and precision of the data expression, the integrity, normalization and consistency of the data organization, the feasibility of the data application, etc. We must check the quality of GIS spatial data. This paper discussed data check of GIS spatial data, analyzed the source of the data error, the mode and the way to check data. And the data check module is programmed to check the test data, the result of the test showed us that the way of data check is feasible.
