【摘要】 SPOT-5影像的高分辨率和高信息量的性质,使其得到了广泛的应用,特别是在全国第二次土地利用调查中得到了更加深入的应用。而数字正射影像的制作是SPOT-5遥感影像应用的关键所在。本文在介绍DOM制作的基础上,依据当前获取GCP主要的三种途径采用ERDAS遥感图像处理软件进行了实验,并对最终的结果精度进行分析,总结了DOM制作过程的相关问题。更多还原

【Abstract】 With the ascendant nature of high resolution and large amount of information,the SPOT-5 image has been used widely.Especially during the second round of the national land use survey,the use of this image reached a more in-depth level.The production of the digital orthophoto map(DOM)is the key point of the SPOT-5 remote sensing image application.Based on introducing the production of DOM and according to the three main ways of obtaining GCP currently this paper carries out experiments using ERDAS remote sensing image processing software,analyses the accuracy of the final results,and summarizes the related issues during the production of DOM.更多还原
