硐室GIS子系统中属性数据不确定性分析与质量控制

Uncertainties and quality control for attribute data in a dit GIS

根据硐室GIS子系统开发过程中由采集的属性数据直接生成的硐室空间图形的特点,分析了属性数据不确定性,提出了硐室空间数据质量的提高与属性数据的质量的提高密切相关。针对这一情况,提出了一种硐室GIS子系统中属性数据质量的检验、度量和分析的缺陷率分层抽样模型,并基于该模型,以某硐室属性数据为例,建立了该模型在硐室GIS子系统中进行属性数据质量评价的具体思路。

In the progress of adit GIS development ,the uncertainties of attribute data can be analyzed based on the characteristic that attribute datum are used to get the spatial graphics of adit , and the quality of graphics of adit is closely to the attribute data. Focused on this situation, the module of disfigurement stratified sampling is put forward to measure the accuracy of attribute data of adit GIS,inspection ,determination and analysis of quality of the attribute data of the adit are discussed ,based on this module and the attribute data of some adit.
