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.

Long-term monitoring and remote sensing reveal waterbird colony collapses with rising lake levels and multiple stressors. [PDF]
Ecol ApplAbstract Global climate change is expected to exacerbate existing environmental stressors and increasingly impact biodiversity. While likely widespread, changes in wildlife populations resulting from the interaction of climate change and other environmental stressors remain poorly understood.

Comprehensive Analysis of Bias in TEMPO NO<sub>2</sub> Column Densities Through Pandora Observations. [PDF]
J Geophys Res AtmosAbstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) is the first geostationary satellite instrument to monitor air pollutants across North America. This study uses Pandora observations to analyze the bias in TEMPO Level‐3 total column density of NO2 (TOTNO2) from August 2023 to December 2024.

POINT-TO-SURFACE MATCHING FOR DEM CORRECTION USING ICESAT DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Vendor-provided rational polynomial coefficients (RPCs) are commonly used to generate digital elevation models (DEMs) from high-resolution satellite images. This results in a level of accuracy that can be improved using ground control points (GCPs).
