The research aims to develop an automated remote sensing framework for classifying alpine wetland types in the Qinghai Lake Basin.
Integrated Sentinel-2 optical imagery and Sentinel-1 SAR data for wetland classification.
Utilized an object-based image analysis (OBIA) framework.
Employed the SEaTH algorithm for feature selection before applying a Random Forest model to classify wetland types.
Achieved an overall accuracy of 82.53% and a Kappa coefficient of 0.74 with the initial model.
The SEaTH-based optimization improved accuracy to 86.24% with a Kappa coefficient of 0.79.
Enhanced classification performance by increasing producer’s accuracy by 3.96–6.11%.
The proposed framework is effective for large-scale mapping of alpine wetlands.
