Automatic GCP creation for NOAA AVHRR image geometric correction

Geometric correction methods for NOAA AVHRR image include the GCP (ground control point). Recently, many discussions about the accuracy of geometric correction have been held and many high accuracy geometric correction algorithms for NOAA AVHRR images have been proposed. However, they are not suitable for the time series analysis that processes a large amount of image because they need the manual procedures for the creation of GCP. In this research, we paid attention to this point and developed the completely automatic GCP creation method. The processing time of this method was about 1 second. So, it was confirmed that GCP was generated at very high speed
