- GOCI image has a radiometric stray light, called as inter-slot radiometric discrepancy
(ISRD), which means radiometric inconsistency between the adjacent slots. The Correction of Interslot radiometric Discrepancy Using the Minimum noise fraction transform, namely CIDUM, is in
effect to reduce ISRD in the GOCI Level 1B.
This research evaluates for reduction of horizontal ISRD in remote sensing reflectance (Rrs)
data, which is retrieved from GOCI Level 1B data corrected byCIDUM. Atmospheric
correction is performed by GOCI Data Processing System (GDPS) V.2.0. For the evaluation the
bottom image in ISRD area where northern and southern images are overlapped is
assumed as reference data. The horizontal discrepancy is mitigated in all ISRD area and
the differences between upper- and bottom- slots becomes close to 0. But it doesn’t work for
blue bands effectively.
