本文应用小波理论建立了多分辨率分析与GIS图形数据多比例尺表达的关系,在此基础上提出了一种基于多分辨率分析的自动制图综合模型,并以线状要素自动综合为例,说明了新模型方法的应用。
Based on the wavelet theory, the relation between multiresolution analysis and multi scale data expression in GIS is found, a new model of using multiresolution analysis is put forth, and the application example to use the proposed model is given in this paper
