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.本数据集包含经预处理的光学与合成孔径雷达（Synthetic Aperture Radar, SAR）图像块，以及手动解译得到的热融滑坍（retrogressive thaw slump, RTS）标注，相关内容用于研究论文《基于光学与SAR影像的双记忆驱动多模态序列融合网络开展热融滑坍制图》（原英文标题："A Dual-Memory-Driven Multimodal Sequence Fusion Network for Retrogressive Thaw Slump Mapping Based on Optical and SAR Images"）。本数据集基于哨兵-1A SAR数据与哨兵-2A光学影像构建，其中RTS标注通过人工解译生成。
