摘要
对目前空间数据质量评价的方法进行了研究,总结了现有方法存在的问题,提出用直觉模糊集理论对空间数据质量进行评价,通过实例分析所得结果证明了用直觉模糊集理论进行空间数据质量评价的科学性,并分析了直觉模糊集理论的评价方法存在的问题。
Studied the current method of spatial data quality evaluation, the existing problems of the method were summarized , intuition-istic fuzzy set theory was proposed to evaluate the quality of spatial data. Results of the instance analysis proved the scientific nature of spatial data quality evaluation by using intuitionistic fuzzy set theory. Finally, the problems of the evaluation method based on intuitionis-tic fuzzy set theory were analysed.
