| 摘 要： | 针对计算机地图综合仍然以人机交互的方式为主的现状,本文根据地图综合操作中的符号可视化的四个特点,提出了建立以单套比例尺符号库适宜多套比例尺地形图数据的可视化方案。通过定义不同比例尺之间符号的衰减系数,讨论了单套比例尺可视化多套比例尺数据的实现方式,并结合1:1万地形图缩编至1:5万地形图进行了模拟实验。

| Abstract: | The automatic generalization is mainly carried out by the interaction between man and computer.According to the characteristics of map visualization aiming at the operation of generalization,this paper presents a method to realize the visualization of multi-scale map by one-scale symbolic library.After the definition of the reduction coefficient of different map scales,this paper computes the reduction coefficient from 1∶10 000 map to 1∶50 000 ma Pand carries out an experiment on these two map scales.The end of this paper analysis some other problem in this method of visualization. |
