NRWI: a novel spectral index optimized for waterbody extraction from high-resolution GF-2 satellite imagery
Published 2025-12-01Get full textRemote sensing-based water indices are well-suited for rapid, large-scale waterbody extraction. However, most existing indices rely on short-wave infrared (SWIR) bands, making them incompatible with four-band high-resolution satellite imagery (visible and near-infrared only). Moreover, the few indic...

Dynamic monitoring of fine-grained ecological vulnerability in dryland urban agglomeration integrating novel remote sensing index and explainable machine learning
Published 2025-12-01Get full textRapid urbanization and climate change are exacerbating ecological vulnerability in dryland urban agglomerations, threatening ecosystem stability and sustainability. However, persistent technological gaps in large-scale, fine-grained and long-term monitoring hinder a comprehensive understanding of vu...
