ROSIS Hyperspectral Imagery of Pavia, Italy

Pavia Centre and University are two hyperspectral image scenes captured by the ROSIS sensor during a flight campaign over northern Italy. The Pavia Centre scene is a 1096 x 1096 pixel image with 102 spectral bands, while Pavia University is 610 x 610 pixels with 103 bands, both at a 1.3-meter geometric resolution. The dataset was uploaded by author 'danaroth' to Hugging Face in November 2023.

Use Cases

• Classify land cover types using the 102-103 spectral bands per pixel for scene segmentation.
• Benchmark pixel-wise classification algorithms on the 1096x1096 and 610x610 pixel image grids.
• Develop spectral unmixing models to identify material composition from the high-dimensional spectral signatures.
• Train models for noise removal or inpainting by handling pixels marked as containing no information.
• Compare model performance on two distinct urban and university scenes from the same sensor campaign.

Strengths

• High spatial resolution of 1.3 meters per pixel.
• Contains two distinct scenes with 102 and 103 spectral bands respectively.
• Large image dimensions: 1096x1096 pixels for one scene and 610x610 for the other.

Limitations

• Specific sample counts (rows) for valid pixels are not provided in the description.
• Some pixels in both images contain no information and must be discarded, indicating incomplete data.
• The dataset's size, license, and exact temporal coverage of the flight campaign are unknown.
