MArine Debris hyperspectral reference Library collection (MADLib)

This spectral reference library collection, MADLib, contains 24,889 curated hyperspectral reflectance measurements from 3,032 samples of marine debris—both plastic and non-plastic—compiled from 13 datasets. The objective is to support the development of robust remote sensing algorithms for detecting marine debris by providing standardized, comprehensive data. This applied research compiles reflectance data collected through hyperspectral imaging under controlled conditions, including indoor and outdoor measurement environments. Spectra were harmonized and paired with standardized metadata that capture key characteristics such as polymer type, color, size, weathering, aqueous state, and experimental design. MADLib addresses prior inconsistencies in data curation and enhances accessibility for future algorithm development.

本光谱参考库MADLib包含24889条经标准化质控的高光谱反射率（hyperspectral reflectance）测量数据，这些数据源自13个数据集，覆盖3032份海洋废弃物样本（涵盖塑料与非塑料两类）。本数据集的构建目标为，通过提供标准化且全面的参考数据，支撑海洋废弃物探测用鲁棒性遥感算法的研发工作。本研究集合了通过高光谱成像技术在可控环境（包含室内与室外测量场景）下采集的反射率数据。所有光谱数据均经过统一校准，并与标准化元数据（metadata）进行关联，该元数据涵盖了聚合物类型、颜色、尺寸、老化风化程度、浸水状态以及实验设计方案等关键特征。MADLib解决了过往海洋废弃物光谱数据集在数据质控环节存在的不一致性问题，并提升了数据可访问性，可为后续遥感算法的研发提供支撑。
