cross-scene hyperspectral image datasets

1) RPaviaU-DPaviaC Dataset: The RPaviaU-DPaviaC dataset is constructed by amalgamating two publicly accessible HSI datasets: the ROSIS Pavia University (RPaviaU) scene and the DAIS Pavia Center (DPaviaC) scene. The RPaviaU dataset, featuring dimensions of 610 × 340 × 103, was acquired by the ROSIS HSI sensor over the terrain of the University of Pavia, Italy. Conversely, the DPaviaC dataset, with dimensions of 400 × 400 × 72, was collected using the DAIS sensor over the central area of Pavia City, Italy. These two scenes share a common set of seven land cover classes. 2) EHangzhou-RPaviaHR Dataset: The EHangzhou-RPaviaHR dataset encompasses two distinctive scenes: the EO-1 Hangzhou (EHangzhou) scene and the ROSIS Pavia HR (RPaviaHR) scene. The EHangzhou scene, sourced from the EO-1 Hyperion hyperspectral sensor, was obtained over Hangzhou City, Zhejiang, China, and possesses dimensions of 590 × 230 × 198. In contrast, the target scene, RPaviaHR, was captured using the ROSIS HSI sensor over Pavia city, Italy, and is characterized by dimensions of 1400 × 512 × 102. These two scenes share a common subset of three land cover classes.

1) RPaviaU-DPaviaC 数据集：该数据集由两份公开可获取的高光谱（Hyperspectral Imagery, HSI）数据集融合构建而成，分别为ROSIS帕维亚大学场景（ROSIS Pavia University, RPaviaU）与DAIS帕维亚市中心场景（DAIS Pavia Center, DPaviaC）。其中RPaviaU数据集尺寸为610×340×103，由ROSIS高光谱传感器在意大利帕维亚大学校园区域采集获取；DPaviaC数据集尺寸为400×400×72，由DAIS传感器在意大利帕维亚市中心区域采集得到。这两个场景共享7类共同的土地覆盖类别。
2) EHangzhou-RPaviaHR 数据集包含两个特色场景：EO-1杭州场景（EO-1 Hangzhou, EHangzhou）与ROSIS帕维亚高分辨率场景（ROSIS Pavia HR, RPaviaHR）。其中EHangzhou场景源自EO-1 Hyperion高光谱传感器，于中国浙江省杭州市上空采集，尺寸为590×230×198；目标场景RPaviaHR由ROSIS高光谱传感器在意大利帕维亚市上空采集，尺寸为1400×512×102。这两个场景共享3类共同的土地覆盖类别。

背景与挑战

背景概述

该数据集是一个用于跨场景高光谱图像分类的标准遥感数据集，包含两个子数据集：RPaviaU-DPaviaC和EHangzhou-RPaviaHR。每个子数据集由两个不同地理区域（如意大利帕维亚和中国杭州）采集的高光谱图像场景组成，具有不同的传感器、尺寸和光谱波段，但共享部分相同的土地覆盖类别，旨在支持跨场景的模型训练与评估研究。
