RapidEye卫星遥感影像几何精度的实验分析

Geometric accuracy experimental analysis of remote sensing image of RapidEye satellite

对一景RapidEye的3A级数据进行实验,测定了该数据的真实空间分辨率。通过4种不同的方法对影像做几何纠正,并对该影像的内部几何误差作了分析。得出的RapidEye数据完全可以满足1?500 00地形图数据的更新。

The experiments to the data of a scene image of RapidEye 3A were made to determine the true spatial resolution of the data.The geometric correction to the image was carried out through four kind of different methods,and the internal geometric error of the image was analyzed.Finally,we confirmed that the RapidEye data obtained from the experiments could fully met the requirement of updating data of 1︰500 00 topographic map.
