“…The GOCI can acquire images in eight bands (six visible bands, two near-infrared bands). The GSD (ground sample distance) of GOCI at the center of target area is 500 m. Since GOCI can perform acquiring and transferring 16 slots in less than 30 min [1], the time intervals between slots was less than 1.875 min. In this paper, we used the near infrared No.…”

Current precise geometric correction of Geostationary Ocean Color Imager (GOCI) image slots is performed by shoreline matching. However, it is troublesome to handle slots with few or no shorelines, or slots covered by clouds. Geometric correction by frequency matching has been proposed to handle these slots. In this paper, we further extend previous research on frequency matching by comparing the performance of three frequency domain matching methods: phase correlation, gradient correlation, and orientation correlation. We compared the performance of each matching technique in terms of match success rate and geometric accuracy. We concluded that the three frequency domain matching method with peak search range limits was comparable to geometric correction performance with shoreline matching. The proposed method handles translation only, and assumes that rotation has been corrected. We need to do further work on how to handle rotation by frequency matching.
