Analyzing on uncertainty of multi-scale representation of street-block settlement

本文对街区式居民地多尺度表达的不确定性进行了分析,认为制图综合是街区式居民地多尺度表达存在不确定性的根本原因,并挖掘探讨了街区式居民地多尺度表达不确定性的本质及其分类。针对街区式居民地多尺度表达的各类不确定性,重点分析并确立了用街区式符号表达居民地时的不确定性类型及评价指标和方法。本文的研究成果可以应用于街区式居民地多尺度表达尺度转换方法优劣及产品不确定性的评估。

This paper pointed out that map generalization is the essential cause leading to uncertainty of multi-scale representation for street-block settlement. Furthermore, it was explored of essence and types of uncertainty on multi-scale representation for street- block settlement. According to the each kind uncertainty of multi-scale representation for street-block settlement, this paper mainly es- tablished the type of uncertainty of its expression symbols, evaluation method and indexes. The result could be used for evaluating on scale transfer methods of multi-scale representation of street-block settlement and uncertainty of products.
