| 摘 要： | 矢量地图数据作为GIS数据的一种主要形式,其质量问题受到很大的重视。目前对矢量地图数据的质量评价有许多种方法,应用比较多的是模糊综合评判。但是,运用此方法会出现失效现象,本文在分析矢量地图的质量元素基础上,针对现有的质量模糊综合评判失效问题进行了探讨;提出了带信任度的模糊综合评判方法,较好解决了评判过程中的失效问题,提高了评判效率以及评判结果的可靠性。

Solution on lost efficacy in quality evaluation of vector map data based on fuzzy judgment |
| |
| Abstract: | As a primary form of GIS data,vector map data has been paid much attention to its quality.Fuzzy judgment is the common one of the many methods in the quality evaluation.This paper analyzed the quality elements of vector map data,and discussed the problems of inefficiency in fuzzy synthetic product.Furthermore,it put forward the fuzzy synthetic judgment in the quality evaluation of the vector map data with the trust degree.The method could solve the inefficiency of judgment with more efficiency and feasibility. |
