Dataset for DMM-Net: Optical-SAR Retrogressive Thaw Slump Mapping

This dataset contains processed optical-SAR image patches and manually interpreted retrogressive thaw slump (RTS) labels used in the study “A Dual-Memory-Driven Multimodal Sequence Fusion Network for Retrogressive Thaw Slump Mapping Based on Optical and SAR Images”. The dataset was constructed from Sentinel-1A SAR data and Sentinel-2A optical imagery, with RTS labels generated through manual interpretation.
