摘要
地形图体现测量时的地形地貌,随着城市建设和自然风蚀的影响,其逐渐与实地现状不一致,故实施地形图修测很有必要。本文基于卫星遥感影像的地形图修测方法进行了具体试验,提出了具体思路和作业流程,对地形图快速修测方法进行了有益探索。
Topographic measurement reflects the state of The earth＇s surface fluctuation , With the impact of urban con struction and natural wind erosion, topographic map was gradually out of keeping with realities on the ground . There fore, it is necessary to implement the terrain resurvey. Based on the revision method of remote sensing topographic map , this paper conducted a detailed test. It put forward specific ideas and processes and has quickly carried on the beneficial exploration for the topographic map revision method.
