随着GIS数据采集规模的扩大和更新速度的提高,对GIS属性数据质量的检查、度量和控制变得越来越重要。基于抽样检验在测量数据精度分析中的思想,提出基于抽样的缺陷率方法对GIS属性数据的精度进行度量。同时根据大多数GIS数据分层存储的特点,进一步提出采用分层抽样技术检验属性数据缺陷的方法,并给出基于分层抽样的属性数据精度的缺陷率模型和应用实例。

It is a critical research topic to measure and control accuracy of attribute data in the overall research framework accuracy in GIS data. This has become an even more important issue, particularly when more and more GIS data needs to be collected and updated. Sampling technique has been adopted in the area of surveying data processing for years. In this paper, the method of rate of disfigurement is proposed to measure accuracy of attribute data in GIS. The stratified sampling technique is ...
