Vegetable Index (NDVI) of Andalusia, 1995 (LANDSAT TM)

Images of the Landsat 5 satellite captured by the TM (Thematic Mapper) sensor that have been calculated the Normalised Difference Vegetation Index (NDVI), which based on the contrast between the red and near infrared bands of the spectrum, highlights the vegetation cover and its vigorousness over large areas. It is composed of 9 images from 1995 with a single band spectral resolution and a spatial resolution of 30 m.本数据集包含基于陆地卫星5号（Landsat 5）的专题制图仪（Thematic Mapper，简称TM）传感器采集的原始影像计算得到的归一化差分植被指数（Normalised Difference Vegetation Index，简称NDVI）影像。该指数通过光谱红色波段与近红外波段的对比度运算，可凸显大尺度范围内的植被覆盖状况及其生长活力。数据集由1995年的9幅单波段影像组成，空间分辨率为30米。
