简介：本数据集为改良版肯塔基草地(KSC)高光谱图像集合，适用于各类分类算法的研究与测试。
On March 23, 1996, NASAs AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) instrument collected data over the Kennedy Space Center in Florida. The AVIRIS collects data across 224 bands with a width of 10 nm and center wavelengths ranging from 400 to 2500 nm. Data were acquired at an altitude of approximately 20 km, resulting in a spatial resolution of 18 meters. After removing water absorption and low signal-to-noise ratio (SNR) bands, the analysis used 176 remaining bands.
Training data for classification were selected based on land cover maps derived from color infrared photography provided by Kennedy Space Center and Landsat Thematic Mapper imagery. A vegetation classification scheme was developed at KSC to define functional types that are discernible at both Landsats spatial resolution and that of the AVIRIS data. The similarity in spectral signatures for certain vegetation types makes it challenging to distinguish land cover classes.
For this analysis, 13 distinct land cover categories were defined to represent various environmental conditions present within the Kennedy Space Center area.
