First GEOKOMPSAT-2A imagery (in stereo view with Himawari-8)
The Korean Meteorological Administration (KMA) has released its first true-color image created with data from the AMI sensor on the GEOKOMPSAT-2A (GK2A) satellite that was launched in late 2018. This first image from GK2A is experimental and preliminary, just like the initial images from Himawari-8, -9, GOES-16 and GOES-17 were preliminary: all newly-launched satellites go through a check-out period during which radiometric and geometric calibration work is ongoing. That is what is happening with the GK2A satellite now. Despite the preliminary nature of the GK2A imagery, however, it can be paired with Himawari-8 imagery to create stereoscopic views of the Earth — in true color! To view the image pair in three dimensions, cross your eyes until three circles appear, and focus on the circle in the middle; it should appear then as a sphere.
