Water depth estimation from Sentinel-2 imagery using advanced machine learning methods and explainable artificial intelligence

نویسندگان

چکیده

The estimation of water depth in coastal areas and shallow waters is crucial for marine management monitoring. However, direct measurements using fieldwork methods can be costly time-consuming. Therefore, remote sensing imagery a promising source geospatial information planning development. To this end, study investigates advanced machine learning (ML) redesigned morphological profiles high-resolution Sentinel-2 satellite imagery. proposed framework involves three main steps: (1) feature generation, (2) model training several ML (Decision Tree, Random Forest, eXtreme Gradient BOOSTing, Light Boosting Machine, Deep Neural Network, CatBoost), (3) interpretation eXplainable Artificial Intelligence (XAI). performance the method was evaluated two different (port jetty) with reference data from accurate hydrographic (Echo-sounder differential global positioning systems). statistical analysis revealed that had high efficiency area, achieving best R2 value 0.96 Root Mean Square Error (RMSE) 0.27 m Chabahar Bay Oman Sea. Additionally, higher impact interaction features were verified XAI mapping.
