Abstract :
Although lacking fine resolution as airborne sensors, satellite thermal remote sensors are important to urban thermal pattern researches. With the help of downscaling methods and spectral mixing analysis, medium spatial resolution thermal infrared satellite data can retrieve subpixel thermal characteristics by integrating higher resolution and multi-spectral data. Combining SPOT-5 and ASTER is a practical downscaling method among them. Several different means in such procedure are compared and result is acceptable.
