查询词典 spatial

In GIS, data quality is one of the key aspects.The Recent studies of data quality in GIS most focus in the error of spatial data. The error study on attribute data is very weak. Most studies centralize in precision analysis of attribute data from remote sensing and introduction of new method. The studies of attribute information quality stored in RDB are very weak.

近年来，GIS数据质量的研究集中在位置数据的误差上，而对属性数据误差的研究较少，多年来的研究主要集中在遥感分类属性数据的精度分析和一些新方法的引入上，而关系数据库存储的属性信息质量方面的研究相对比较薄弱。
