--- license: unknown --- # Description The Pavia Centre and University are two scenes acquired by the [ROSIS](http://www.opairs.aero/rosis_en.html) sensor during a flight campaign over Pavia, nothern Italy. The number of spectral bands is 102 for Pavia Centre and 103 for Pavia University. Pavia Centre is a 1096 $\times$ 1096 pixels image, and Pavia University is 610 $\times$ 610 pixels, but some of the samples in both images contain no information and have to be discarded before the analysis. The geometric resolution is 1.3 meters. Both image groundtruths differenciate 9 classes each. It can be seen the discarded samples in the figures as abroad black strips. # Characteristics **Groundtruth classes for the Pavia centre scene and their respective samples number** | # | Class | Samples | |---|----------------------|---------| | 1 | Water | 824 | | 2 | Trees | 820 | | 3 | Asphalt | 816 | | 4 | Self-Blocking Bricks | 808 | | 5 | Bitumen | 808 | | 6 | Tiles | 1260 | | 7 | Shadows | 476 | | 8 | Meadows | 824 | | 9 | Bare Soil | 820 | **Groundtruth classes for the Pavia University scene and their respective samples number** | # | Class | Samples | |---|----------------------|---------| | 1 | Asphalt | 6631 | | 2 | Meadows | 18649 | | 3 | Gravel | 2099 | | 4 | Trees | 3064 | | 5 | Painted metal sheets | 1345 | | 6 | Bare Soil | 5029 | | 7 | Bitumen | 1330 | | 8 | Self-Blocking Bricks | 3682 | | 9 | Shadows | 947 | # Quick look <figure> <img src= "assets/Pavia_60.png" alt="Pavia" width="300" /> <figcaption>Sample band of Pavia Centre dataset.</figcaption> </figure> <figure> <img src= "assets/Pavia_gt.png" alt="Pavia gt" width="300" /> <figcaption>Groundtruth of Pavia Centre dataset.</figcaption> </figure> <figure> <img src= "assets/PaviaU_60.png" alt="PaviaU" width="300" /> <figcaption>Sample band of Pavia University dataset.</figcaption> </figure> <figure> <img src= "assets/PaviaU_gt.png" alt="PaviaU gt" width="300" /> <figcaption>Groundtruth of Pavia University dataset.</figcaption> </figure> # Credits Pavia scenes were provided by [Prof. Paolo Gamba](http://tlclab.unipv.it/sito_tlc/people.do?id=pgamba) from the [Telecommunications and Remote Sensing Laboratory](http://tlclab.unipv.it/), [Pavia university](http://www.unipv.eu/) (Italy).

The Pavia Centre and Pavia University datasets are two hyperspectral image scenes acquired by the ROSIS sensor during a flight over Pavia, northern Italy. The Pavia Centre image is 1096x1096 pixels with 102 spectral bands, while the Pavia University image is 610x610 pixels with 103 spectral bands. Both have a geometric resolution of 1.3 meters and ground truth data differentiating 9 classes each. Some samples are discarded due to lack of information before analysis. The dataset is provided by the Telecommunications and Remote Sensing Laboratory at the University of Pavia.
数据集描述
Pavia Centre 和 Pavia University 是由 ROSIS 传感器在意大利北部 Pavia 的一次飞行活动中获取的两个场景。Pavia Centre 有 102 个光谱带,Pavia University 有 103 个光谱带。Pavia Centre 是一个 1096 × 1096 像素的图像,而 Pavia University 是 610 × 610 像素,但这两个图像中的一些样本不包含信息,需要在分析前丢弃。几何分辨率为 1.3 米。两个图像的地面真实数据分别区分 9 个类别。丢弃的样本在图中显示为宽阔的黑色条纹。
