PGMMF-Net: a POI-Guided Multi-modal Mamba Fusion Network for urban impervious surface extraction from optical and SAR imagery

Accurate extraction of urban impervious surfaces (IS) is essential for urban environmental analysis. However, optical-based methods are affected by shadows and spectral confusion, while optical-SAR fusion lacks urban functional semantics. Point-of-interest (POI) data provide comp...
