High-speed and precise geometric correction for GMS S-VISSR data

In this paper, high-speed and precise geometric correction for GIMS S-VISSR data is described. Bi-linear interpolation is used for speeding up the geometric correction. The precise correction is carried out by using the ground control points. Moreover, the geometric correction considering the elevation is applied in land area. In the case of the correction on infrared channels, visible and infrared channels are used. As a result, the maximum of errors in the proposed method is 0.01 degree in the both direction of latitude and longitude
