地图缩编在测绘生产中的应用

城市建设的不断发展,测绘生产越来越多地融入到经济建设和人们的日常生活中。随着测绘信息化的不断推进,需要测绘成果在一定情况下实现共享,有利于实现测绘成果的合理化应用。利用已有大比例尺数字地形图缩编成所需比例尺的数字地形图的工作也日渐增多。本文以1∶500地形图缩编成1∶2 000地形图为例,总结了地图缩编在测绘生产中应用的技术要点。

The continuous development of city construction, surveying and mapping production more and more into the economic con-struction and people's daily life.With the continuous advance of informationization surveying and mapping, surveying and mapping re-sults sharing need in certain circumstances.Is conducive to the rational application of surveying and mapping achievements.Using a large scale digital topographic map generalization into existing digital topographic map required scale work is also increasing.Taking 1∶500 topographic map downsizing of 1∶2 000 as an example, summarizes the key technical points in the map generalization in cartog-raphic generalization.
