【摘要】 利用现有大比例尺数字化地形图缩编成所需比例尺的数字地形图,不仅可以节约成本,而且可以减少成图时间。为此,介绍了一种利用1∶500数字化地形图缩编1∶2 000地形图的方法。实践证明,该方法能以半自动化的方式缩编地形图,并能大大提高工作效率。更多还原

【Abstract】 Downsizing the existing large scale digital topographic map into a map required scale not only can save cost but also can reduce mapping time. Therefore,this paper indroduces a method of the topographic map generalization from 1∶ 500 scale to 1∶ 2 000 scale. The facts show that,this method can downsize the topographic map in a semi-automatic fashion,and can greatly improve the work efficiently.更多还原
