MONITORING OF MEDIUM-SIZED RESERVOIRS USING MULTI-SATELLITE IMAGERY AND FUZZY C-MEANS CLUSTERING

Speaker: Wanyub Kim, Sungkyunkwan University, Republic of KoreaSatellite remote sensing data can provide continuous observations over large areas, making it an effective tool for reservoir monitoring (Zhang et al., 2022). In general, satellite remote sensing data used for water body detection is divided into optical and radar sensor observations. Optical imagery has the advantage of being able to detect water bodies with a high accuracy (Cordeiro et al., 2021). Nevertheless, it has the limitation that continuous monitoring is difficult due to cloud cover (Yang et al., 2018). In contrast, Synthetic Aperture Radar (SAR) imagery provides continuous water body detection regardless of weather conditions, however it has the limitation of lower detection performance (Grimaldi et al., 2020). Therefore, the combination of SAR and Optical imagery has been proven to complement each others limitations, enabling more efficient reservoir monitoring.
