ADEOS/OCTS is an optical sensor with a low resolution and a frequent observation period for mainly observing ocean color and temperature. The highly precise geometric correction is necessary for some applications such as multi-temporal analysis, generation of floud free composite images, etc., where the accuracy of less than one pixel is preferable. But the accuracy by the system correction is not sufficient to those requirements.
The authors have developed the system for precise geometric correction of NOAA/AVHRR imagery. The system utilizes GCPs and is adaptable for any number of GCPs. The system has been modified for OCTS imagery.
In this paper, the differencies of OCTS from other sensors like AVHRR are pointed out at first and the modifications for the geometric correction of OCTS imagery are described.
