摘要 通过归一化植被指数(NDVI)结合影像差值,对经过辐射校正后的1993年和2005年武汉地区TM影像进行了土地利用变化检测,与监督法分类进行比较,得出NDVI更宜于实现变化信息探测和提取。 This paper combined Normalized Difference Vegetation Index (NDVI) method with the image margin. Experiments with the land-use change detection of radiation calibrated TM image in Wuhan of 1993 and 2005 show that compared with supervision classification, the NDVI achieve more desirable change detection and information extraction.
