高分二号卫星遥感影像在地形图修测中的应用

Application of Remote Sensing Images of Gaofen-2 Satellite on Topographic Map Revision

1∶10000地形图作为基础测绘的重要组成部分,在国民经济发展中发挥着举足轻重的作用。如何高效、高质量地完成地形图修测工作,一直受到测绘工作者们高度重视。利用传统测绘技术进行地形图修测工作,往往费时费力,成本较高;效率较高的无人机航测技术也有它自身的局限性。近年来,国家一直致力于推广应用高分二号卫星,因此本文研究探讨了将高分二号卫星影像应用于1∶10000地形图修测工作的可行性,并得出了比较可靠的结论。

As an important part of basic surveying and mapping,1∶10000 scale topographic map plays a pivotal role in the development of the national economy.To complete topographic map revision and survey work efficiently with high quality has always been a matter of great importance to surveying and mapping workers.The use of traditional surveying and mapping technology for topographic map revision and survey is often time-consuming,laborious and costly.The more efficient UAV aerial photogrammetric technology also has its own limitations.In recent years,the country has been committed to the application and promotion of Gaofen series satellite images.Therefore,this article explores the feasibility of applying the Gaofen-2 satellite images to the 1∶10000 scale topographic map revision and survey work,and draws a more reliable conclusion.
