遥感影像结合RTK绘制中大比例尺地形图的应用研究

Research on Application of Medium and Large Scale Topographic Map in the Technique of Remote Sensing Images Combined with RTK

Quick Bird卫星是目前全世界最高分辨率的商用卫星,利用现势的高分辨率的遥感影像,经过精确的变换和正射几何纠正后,得到正射影像,经过判读识别地物,对大比例尺地形图进行快速更新。随着GPS技术快速发展,GPS RTK的精度是完全可以满足在地形图的图根控制中测量的要求。GPS RTK技术以作业速度快、生产组织灵活、实时测定待测点的坐标、手持单杆作业等优点已经在现代的测绘行业中得到了普及,本文用RTK测量遥感影像的控制点,通过控制点对遥感影像的几何纠正后,利用数字成图软件绘制数字地形图。这种方法快捷、经济,为今后的测绘生产提供了一种新的参考。

Quick Bird is the best one of high solution commercial satellite in nowadays.Using the high resolution images can obtain digital orthophoto map after the process of transform and geometric correction,also can quickly update the large scale topographic map by interpreting the subjects on the earth.With the development of GPS technique,the accuracy of GPS RTK can meet the requirements of surveying topographic map,and the GPS RTK technique has popular in modern surveying and mapping industry.This paper introduced the method of surveying control points of remote sensing images by using GPS RTK,and drawing digital topographic map by using related software.This method provided a new reference for surveying and mapping industry in the future.
