| 摘 要： | 利用3对同日过空的ASTER和ETM+影像对,开展了ETM+和ASTER热红外影像的定量比较,求出了二者的关系转换方程。定量研究结果表明,ASTER和ETM+热红外数据具有极显著的正相关关系,所求出的转换关系方程有很高的精度。但二者仍有一定的差异,表现在ASTER数据反演的传感器处温度要比ETM+平均高0.66℃~0.82℃,其所表现的热信息量也要比ETM+丰富且连续。

| Abstract: | A tandem cross calibration between ASTER's and Landsat ETM+'s thermal data was carried out.Three simultaneous TIR image pairs of the two sensors,each of which imaged on common ground targets,were used to quantitatively compare the thermal quality ofthe two sensors.The comparison has been made between Landsat ETM+ band 6 and ASTER bands 13 and 14.The result shows that an excellent agreement between the at-sensor temperatures obtained from both sensors for the TIR band(s).A very strong positive correlation be... |
