Improving atmospheric correction for KOMPSAT-3A by optimizing the 6SV look-up table

Remote Sensing Letters
We present techniques for enhancing the look-up table (LUT) method, using the Second Simulation of a Satellite Signal in the Solar Spectrum Vector (6 SV) model for atmospheric correction (AC) and accurate surface reflectance (SR) computation across the ...

Ship Detection for KOMPSAT-3A Optical Images Using Binary Features and Adaboost Classification

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
KOMPSAT (KOrea Multi-Purpose SATellite)-3A is a high-resolution earth observation satellite equipped with an electrooptic camera and infrared sensors developed by KARI. In this paper, we introduce a method of detecting ships and estimate the performance with pan-sharpened optical images of 0.55m resolution from KOMPSAT-3A.

A Test Result on the Positional Accuracy of Kompsat-3A Beta Test Images

Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, 2016
KOMPSAT-3A (KOrea Multi-Purpose SATellite-3A) was launched in March 25 2015 with specification of 0.5 meters resolution panchromatic and four 2.2 meters resolution multi spectral sensors in 12km swath width at nadir. To better understand KOMPSAT-3A positional accuracy, this paper reports a test result on the accuracy of recently released KOMPSAT-3A ...

Estimation of surface reflectance using deep neural network with KOMPSAT-3A data

2020
<p>The acquisition of image data from satellite is performed by the satellite’s sensor after the light from the sun is reflected in object at the surface. In this process, light passes through the earth's atmosphere twice and is affected by the scattering, absorption and reflection by the atmosphere.

The radiometric characteristics of KOMPSAT-3A by using reference radiometric tarps and ground measurement

SPIE Proceedings, 2016
In this study, we performed the vicarious radiometric calibration of KOMPSAT-3A multispectral bands by using 6S radiative transfer model, radiometric tarps, MFRSR measurements. Furthermore, to prepare the accurate input parameter, we also did experiment work to measure the BRDF of radiometric tarps based on hyperspectral gonioradiometer to compensate ...
