摘要: 以全国1∶25万土地利用/覆被数据中存在的规范性质量问题为研究对象,利用开源GIS软件构建一个操作简易、评判客观、全面的规范性质量评价系统。这种质量检查系统是基于规则的新型质量评价体系,针对不同的数据质量问题灵活地设计出质量检查规则,并有效集成到系统当中。实验结果表明,系统能灵活、高效地检查出土地利用/覆被数据中的规范性质量问题,并给出客观的评价。

Abstract: Regarding the existing normative data quality issues of the national land use/cover at scale of 1 to 250000 as the research object, the open source Geographical Information System (GIS) software was used to build a normative quality evaluation system that had characteristics of simple operation, objective evaluation and comprehensive inspection. This quality inspection system is a new rules-based quality evaluation system. According to different data quality issues, it flexibly designed quality inspection rules, and effectively integrated into the system. The experimental results show that the system can flexibly and efficiently check out the land use/cover normative data quality issues, and give an objective evaluation.

Key words: Geographical Information System (GIS), data quality, normalization, evaluation model, index base
