| 摘 要： | 通过对Landsat ETM+不同波段遥感影像主要土地利用类型光谱特征曲线进行分析,提出一种新的提取城市建筑用地的方法:V律指数法(V law index,VLI).该方法采用3个波段的遥感影像,并结合约束条件,通过简单的逻辑判断和乘法运算实现建筑用地的提取.随机矩阵点实验测试表明:VLI法能够获得较好的提取效果,与其...

| Abstract: | This paper makes an analyses of the spectral characteristic curves of the major land use categories based on Landsat ETM + different bands remote-sensing images and proposes a new VLI(V law index)method to extract images of urban built-up land.It adopts three-band remote-sensing images and combines with constraints to extract images of urban built-up land using simple logic determination and multiplication operations.Experimental random matrix point tests show that the VLI index,compared with other building... |
