数字南极地理信息公共服务平台建设中的数据质量研究

Research on Data Quality in the Construction of Digital Antarctica Geoinformation Public Services Platform

通过分析地理信息数据生产中的数据质量和空间数据基础设施的数据质量内容和特性,基于数字南极地理信息公共服务平台建设中的数据内容,讨论了在地理信息数据生产和地理信息公共服务平台建设中质量控制和元数据制作工作的重要性,并以保证数字南极地理信息公共服务平台建设的数据质量为目标提出了数据质量元素和评价方法,最后就进一步提高平台数据质量提出了建议。

It firstly analyzed the data quality in geoinformation data production and data quality contents and characteristics in Spatial Data Infrastructure. Based on the data contents in the construction of Digital Antarctica Geoinformation Public Services Platform,this paper discussed the importance of quality control and metadata in the production of geoinformation data and the construction of geoinformation public services platform. Taking the quality improvement of the construction of Digital Antarctica Geoinformation Public Services Platform as the main objective,it put forward the data quality elements and quality assessment methods. Finally,it presented some valuable suggestions for improving the data quality of the platform.
