| 摘 要： | 数据质量的好坏,直接影响着GIS应用分析结果的可靠性及应用目标的实现;而缺少数据质量衡量指标的GIS产品和其他产品一样,将无法得到用户的信任。因此,本文针对GIS数据产品的质量评价问题,基于模糊推理为主的重心综合评判法思想,提出应用模糊重心综合评判法对GIS数据产品的质量进行评价。同时结合实例与模糊评判法进行比较,证明模糊重心综合评判法评判的结果更为合理、可靠,认为其在GIS数据产品的质量评价方面是一种较为科学的方法。

| Abstract: | It is a critical research topic to measure and control quality of GIS data in the overall research framework accuracy in GIS data,and it has become an even more important issue,particularly when more and more GIS data needs to be collected and updated.Based on the fuzzy set judgment method,this paper puts forward a fuzzy gravity center judgment on the evaluation of GIS data product quality,and takes the DEM of Dongzhen reservoir watershed as a case study,it indicates that fuzzy gravity center judgment is more reasonable and credible than fuzzy set judgment,fuzzy gravity center judgment is a scientific method on the evaluation of GIS data product quality. |
