Time-Lapse Hyperspectral Radiance Images of Levada Scene, 7 Images

Time-Lapse Hyperspectral Radiance Images of Levada Scene contains a sequence of 7 hyperspectral radiance images of the Levada scene, acquired at approximately 1-hour intervals. Each image has dimensions of approximately 1344 by 1024 pixels and a spectral range from 400 to 720 nm. The dataset was acquired by Sérgio Nascimento, Kinjiro Amano, and David Foster in the Minho region of Portugal during 2002 and 2003.

Use Cases

• Analyzing spectral reflectance changes over time based on the 1-hour interval time-lapse sequence.
• Developing algorithms for hyperspectral image rendering or compression based on the provided radiance and BMP color images.
• Studying natural scene illumination and color constancy based on the cone excitation ratios referenced in the source publication.
• Training models for environmental monitoring based on the geospatial location information included with the images.

Strengths

• Contains 7 high-resolution hyperspectral images with approximately 1344 x 1024 pixels per image.
• Includes both raw radiance data in MAT format and rendered BMP color images for comparison.
• Provides geographic location data for the scene, enabling geospatial analysis.
• Dataset size is 2.2 GB, indicating a medium-scale collection suitable for many research applications.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data was acquired in 2002-2003; freshness should be verified for contemporary applications.
• Padding artefacts may be visible at the image edges, as noted in the description.
