EXTRACTION OF BUILT-UP AREA BY COMBINING TEXTURAL FEATURES AND SPECTRAL INDICES FROM LANDSAT-8 MULTISPECTRAL IMAGE
Built-up Support Vector Machine Texture
2019/2/28
Remote sensing techniques provide efficient and cost-effective approach to monitor the expansion of built-up area, in comparison to other traditional approaches. For extracting built-up class, one of ...

This paper presents a new application of a data-clustering algorithm in Landsat image classification, which improves on
conventional classification methods. Neural networks have been widely used in ...
Landsat-7 ETM+与ASTER建筑指数的定量比较
Landsat ETM+ ASTER NDBI IBI 交互比较 光谱响应函数
2014/3/17
城市化进程导致的城市建筑用地急剧扩张已对全球的环境资源产生了负面影响,因此亟需对其进行监测。在中尺度卫星对地观测系统中,Landsat 和ASTER数据最适合于监测城市建筑用地变化。但是迄今为止,这两种传感器数据的建筑指数之间的关系并不清楚。因此,利用三对同日过空的ETM+和ASTER影像来查明二者建筑指数(IBI、NDBI)之间的定量关系,通过回归统计分析来求出两种传感器建筑指数之间的转换方程。...
