Time-Lapse Hyperspectral Radiance Images of Gualtar Scene

This dataset contains a time-lapse sequence of 9 hyperspectral radiance images of the scene Gualtar, acquired at about 1-hour intervals. The images are contained in the zipped files, "gualtar_1144.zip" ... "gualtar_1944.zip", each < 350 MB. Thumbnail RGB images rendered from the radiance images are shown in the file Gualtar_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.
