Radiometric calibration and geometric
correction system
The radiometric calibration and geometric correction will be executed in
the LISM RGC processing system in SOAC. The RGC system gets the TC
level 2A data from the L2DB system and processes dark level correction,
flat field calibration, and non-linearity calibration. The TC data processed
in the RGC system are classified into two levels: one is the level 2B (L2B)
data that has radiance values and another is the level 2C (L2C) data that
has reflectance values. We are planning that the reflectance values of L2C
