ETM数据的几何校正
Geometric Correction of ETM Data
-
摘要: 该文对即将发射的Landsat-6 ETM仪器数据的几何校正方法进行论述.文中采用基准 矩阵运算、高频矩阵补偿与三次样条函数重采样算法大大简化处理运算.模拟试验结果证明 图象内部几何精度可达一个象元之内.Abstract: In this paper the method of geometric correction of ETM data from Landsat-6, to be launched in near future, is discussed. By using benchmark matrix calculation, high frequency matrix compensation and cubic spline resampling the correction processing is greatly simplified. The simulation results show that the internal geometric accuracy, of one pixel can be obtained.
