摘要
本文提出对测绘产品的精度应从主要的组成部分进行分析并且提出模糊数学的方法。本文对测绘产品中的主要组成部分的精度分配方法进行了研究。通过分析测绘产品的各组成部分的重要性和精度对于不同用户而言不尽相同,论述了测绘产品不仅含有随机不确定性而且含有模糊性,从而提出了用模糊数学的方法进行测绘产品的精度分配,并介绍了相关的原理和步骤;实例分析得出的结论是客观的、科学的和合理的。
The paper firstly puts forward that mapping product precision should be analyzed from main composing parts with fuzzy mathematics method.It analyses that importance and precision of each composing part of mapping product are different for different users, and discusses that mapping product contains not only random uncertainty but also fuzzy uncertainty.Therefore it proposes to process mapping product precision distribution with fuzzy mathematics method, and simply introduces principle and step of fuzzy mathematics method.The result is impersonal, scientific and reasonable and can guide yield of mapping product, so the method has a definite directing meaning.
