Time-Lapse Hyperspectral Radiance Images of Levada Scene

This dataset contains a time-lapse sequence of 7 hyperspectral radiance images of the scene Levada, acquired at about 1-hour intervals. The images are contained in the zipped files, "levada_1411.zip" ... "levada_1845.zip", each < 350 MB. Thumbnail RGB images rendered from the radiance images are shown in the file Levada_sequence_RGB.pdf, with times of acquisition.Each zipped file contains a hyperspectral radiance image in Matlab MAT format, dimensions approximately 1344 pixels × 1024 pixels and spectral range 400, 410, ..., 720 nm. The zipped file also contains a BMP colour image rendered from the radiance image and an information document, which includes geographic location of the scene. The information document is common to all the images in the sequence. Padding artefacts may be visible at the image edges. The hyperspectral images were acquired by Sérgio Nascimento, Kinjiro Amano, and David Foster from the Minho region of Portugal in 2002 and 2003.This dataset is part of a Collection.

本数据集包含针对Levada场景的7幅高光谱辐射图像（hyperspectral radiance image）的延时序列，采集间隔约为1小时。所有图像存储于压缩文件“levada_1411.zip”至“levada_1845.zip”中，单个压缩文件大小均小于350 MB。从各辐射图像渲染得到的缩略RGB图像已收录于文件Levada_sequence_RGB.pdf，该文件中标注了各图像的采集时刻。每个压缩文件内包含一份Matlab MAT格式的高光谱辐射图像，其尺寸约为1344像素×1024像素，光谱覆盖范围为400 nm、410 nm……720 nm。此外，每个压缩文件中还包含一张由该辐射图像渲染得到的BMP彩色图像，以及一份说明文档，文档中记载了该场景的地理位置信息。该说明文档适用于本序列中的所有图像。图像边缘可能会出现填充伪影（padding artefacts）。这批高光谱辐射图像由来自葡萄牙米尼奥地区的Sérgio Nascimento、Kinjiro Amano与David Foster于2002年至2003年间采集。本数据集隶属于某数据集合集。若您在已发表的研究工作中使用本数据集的高光谱辐射图像或由此渲染得到的彩色图像，请引用如下来源文献：Foster, D.H., Amano, K., & Nascimento, S.M.C.
