Analysis of the Result's Reliability from Fuzzy Assessment of Maps' Quality

Quality assessment is an important step in maps producing, but the traditional approach of score-diminution for defect used in assessing the quality of maps has many inherent defects and leads to coarse and trustless results. In contrast to the traditional approach of score-diminution for defect, fuzzy comprehensive assessment approach takes a complete account of all influential factors and makes full use of the quality information, so it can get a more accurate assessment result. However, current researches on using fuzzy assessment method to map's quality just emphasize how to use this method, while the issue of the result's reliability by fuzzy assessment is neglected hitherto now. Based on the assessment procedure, this paper first discusses the factors that influence the result's reliability by fuzzy assessment. Then with the example of maps' quality assessment, the aspects of the result's invalidity by this method are discussed.
