我们给出了WorldView-2 （WV-2）传感器反射数据的Kauth-Thomas （K-T）变换系数。K-T变换是一种广泛使用的光谱增强方法，它使用一组特征向量将给定的光谱空间变换为定义的特征空间。这个特征空间为用户提供了一个基于物理的坐标，帮助描述单个像素的光谱特征。特征空间中最常用的两种对齐方式是亮度和绿色坐标轴。第一个K-T变换的这些坐标轴已经众所周知，并形成了被称为流苏帽的已定义特征空间的第一个平面。
We present the Kauth–Thomas (K-T) transform coefficients for the reflectance data of the WorldView-2 (WV-2) sensor. The K-T transform is a widely used spectral enhancement, which employs a set of eigenvectors that transforms the given spectral space into a defined feature space. This feature space offers the user a physically based coordinate that helps to describe the spectral signature of the individual pixels. The two most prevalent of the alignments in feature space are the brightness and greenness coordinate axes. These coordinate axes of the first K-T transform have become well known and form the first plan of the defined feature space known as the tasselled cap.
