hyperspectral data over Chikusei

机载高光谱数据集是由Headwall Hyperspec-VNIR-C成像传感器在日本茨城县筑usei的农业和城市地区拍摄的，时间9:56至UTC 10:53 9之间的2014年7月29日。场景的中心点位于坐标: 36.294946n，140.008380E。高光谱数据集具有从363 nm到1018 nm的光谱范围内的128带。场景由2517x2335像素组成，地面采样距离为2.5 m。通过现场调查和目视检查，使用佳能EOS 5D Mark II获得的高分辨率彩色图像以及高光谱数据，收集了19类的地面真相。高光谱数据和地面真相以ENVI和MATLAB格式在http:// park.itc.u-tokyo.ac.jp/sal/hyperdata提供给科学界。实验的更多细节在下面给出的技术报告中介绍。

This airborne hyperspectral dataset was acquired by a Headwall Hyperspec-VNIR-C imaging sensor over agricultural and urban areas in Tsukuba, Ibaraki Prefecture, Japan, from 9:56 to 10:53 UTC on July 29, 2014. The central coordinate of the scene is 36.294946°N, 140.008380°E. The hyperspectral dataset contains 128 spectral bands spanning the wavelength range from 363 nm to 1018 nm. The scene has a size of 2517 × 2335 pixels, with a ground sampling distance (GSD) of 2.5 m. Ground truth labels for 19 classes were collected via field surveys and visual inspection, using high-resolution color images captured with a Canon EOS 5D Mark II and the acquired hyperspectral data. The hyperspectral data and ground truth are publicly available to the scientific community in ENVI and MATLAB formats at http://park.itc.u-tokyo.ac.jp/sal/hyperdata. Further details about the experiment are provided in the technical report presented below.
