层次分析法辅助空间数据质量评价

Analytic Hierarchy Process Aided Spatial Data Quality Assessment

目前对于空间数据的质量评价,参与评价的元素种类繁多,而且各个评价元素之间存在关联性。并且对于不同用途的空间数据,其质量评价的关注点不同,选取的评价元素也不相同。目前多是通过人为经验进行质量评价元素的确定。本文介绍了使用层次分析法确定空间数据质量评价元素的方法,解决了现有的使用主观判断确定质量评价元素的问题,使空间数据的质量评价可量化,也更加系统性、科学性。

At tion between each present, for the spatial data quality evaluation, evaluation elements are variety, and there is a correla- evaluation element. For the different using of spatial data, the evaluation element selection is not the same. At present, determine the quality of evaluation elements through experience. This paper describes the use of the analytic hierarchy process to determine the spatial data quality evaluation element. Using this method determines the quality evaluation elements can be quantified, and more systematic, scientific nature.
