摘要
针对基础地理空间数据的质量特性,结合省级1∶10 000基础地理空间数据在质量检查与控制方面的具体实践和工作体会,从空间数据质量的概念、质量评价、误差来源与分析、质量控制等方面探讨提高空间数据质量的方法与对策。
In this paper, based on the quality characteristics of basic geo - spatial data, and integrating with concrete practice and work experience of quality control for provincial level 1：10 000 basic geo -spatial data production,the methods and countermeasures to improve the quality of spatial data were discussed from the aspects of the concept of quality of spatial data, quality evaluation, error sources and analysis, quality control and so on.
