卫星遥感数据景的地理坐标工程计算

THE ENGINEERING COMPUTATION OF SCENE GEOGRAPHICAL COORDINATE FOR SATELLITE REMOTELY SENSED DATA

在卫星遥感数据预处理中,图像地理坐标是基于卫星观测视线向量的变换和景基准点地理坐标的计算而确定的。本文介绍了景基准点地理坐标的计算原理和运行系统工程计算的实现方案。

In the preprocessing of the remotely sensed data acquired by the satellites, the geographical coordinate of the image are determined on the basis of the conversions of the satellite view vectors, and the computation of the scene benchmark geographical coordinate. This paper introduces the computation principles of the scene benchmark coordinate, and a practical methodical design for an operational engineering system of the data preprocessing.
