基于生产过程的矢量空间数据质量控制研究

Research on Quality Control of Vector Spatial Data Based on Production Process

空间数据质量问题已经成为影响地理信息系统可靠性的主要因素,受到人们越来越多的关注。文章首先针对与质量控制相关的质量管理、质量评价等概念进行辨析,明确质量控制的内涵与外延;进而提出在空间数据的实际生产过程中针对关键性环节加以控制,以保证和提高空间数据的质量。数据生产实践也表明,将数据质量控制的思想与数字制图技术有机结合,在地理信息预处理、数据内容更新与编辑、数据拓扑入库等数据生产重要阶段实施有效的质量检查与控制,对提高数据质量起到了积极的作用。

The quality of spatial data had become a major factor affecting the reliability of GIS,it received more and more affection.Associated with the concept of quality control,quality management and quality assessment were discriminated. The connotation and extension of quality control were defined. The paper proposed quality control of spatial data based on production process,controlled the key issues in spatial data production process,then improved the quality of spatial data. Research had shown that the data quality control theory and digital mapping technology organic combined,which played a positive role to improve the quality data in geographic information pre processing,data updating and editing,topology data producing,etc.
