| 摘 要： | 第二次全国土地调查于2009年底基本完成,本文针对其成果比例尺单一、不能满足各类不同使用目的的用图要求的问题,提出二调成果的多比例尺缩编方法,并采用语义融合、多义线一体化综合、改进的2维Douglas-Peucker算法等相结合策略,高效准确地完成了缩编任务,对全国其他地方刚刚开展的同类型工作提供了一种较好的思路和借鉴。

| Abstract: | The 2nd national land inventory work has basically completed by the end of 2009.Due to the single-scale map,it can't meet the different purposes of land-planning.So the paper proposed the method of multi-scale generalization,which ould fill up this deficiency better.This method combined the semantic mergence and integrative generalization of multi-meanings lines with improved 2D Douglas-Peucker algorithm to finish the generalization efficiently and correctly,which would offer a better way and reference for ... |
