摘要: 地形图缩编是一项系统性、规范性很强的工作。在城市宏观管理和规划中,往往还需要更小比例尺的地形图,如1∶2 000或者1∶5 000。在现有1∶500地形图基础上,若采用重测的方法需要耗费大量的资金和时间。文章论述了由1∶500的地形图缩编至1∶2 000地形图的方法,并详细阐述了其中地形图中各要素缩编的关键过程的处理技巧。该方法可显著地提高缩编过程的效率,节省工作量及大量费用。

Abstract: Topographic map generalization is very systematic and normative. Smaller scale topographic maps are needed in macroeconomic management and planning of the city, such as 1∶2 000 or 1∶5 000. A re-survey method based on the 1∶500 topographic maps requires a lot of money and time. The methods of generalizing topographic map from large scale 1∶500 to 1∶2 000 was proposed, and the skills in treating essential elements of topographic map in key processes were elaborated in detail. This method could significantly improve the generalization efficiency and save a great deal of time and cost, therefore, it showed theoretical and practical importance on topographic map generalization.
