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 ...

Application of Hydroacoustic System and Kompsat-2 Image to Estimate Distribution of Seagrass Beds

Pada (Han'guk Haeyang Hakhoe), 2012
해초지의 생태적 중요성에도 불구하고 국내 연안에 분포하는 해초지 규모에 대한 정보가 미비하다. 장흥군 회진면 일대의 해초지를 대상으로 수중음향측심기와 고해상도 Kompsat-2( 4×4m ) 위성영상을 이용하여 식생유무를 탐지하고 분포크기를 파악하는 연구가 수행되었다. 위성영상을 이용한 식생분석의 정확도는 음향측심기를 통해 얻은 자료분석과 이를 비교하여 검증되었다.

Development of a Surface Reflectance Consistency Algorithm between KOMPSAT-3A and Sentinel-2A/Landsat Satellites

Surface reflectance consistency of multi satellite optical satellites is an essential factor for quantitative Earth observation and multi-satellite data integration. However, due to differences in spectral response functions (SRFs), band definitions, and preprocessing strategies, surface reflectance discrepancy between satellite sensors still exists.In
