| 摘 要： | 本文立足于线状要素多尺度表达的实现过程,利用线状要素多尺度表达的目的,将线状要素多尺度表达的质量需求分解为"4准则",将影响线状要素多尺度表达的质量因素概括为"6因素"。并图表出"6因素"与"4准则"的对应关系。由此推导并建立了线状要素多尺度表达质量评价的概念模型,为线性数据多尺度表达的质量评价问题提供必要的理论依据。

| Abstract: | Based on the implementation process,this paper generalizes the "four rules" of quality demand and "six factors" of affecting quality of multi-scale representation of linear feature making use of the purpose of multi-scale representation of linear feature.It expresses the corresponding relation of "four rules" and "six factors" using figure.It also establishes the concept model of quality estimation of multi-scale representation of linear feature and provides the theory foundation for quality estimation of multi-scale representation of linear feature. |
