Automatic extraction of himalayan glacial lakes with remote sensing
|
Abstract:
The paper develops an automatic lake delineation algorithm based onglobal-localiterative scheme.The author uses NDWI(Normalized Difference Water Index) as the water identification index for the threshold segmentation process,and the slope maps and the shaded relief maps are applied in the algorithm to differentiate the shadow features from water features. Based on these methods,an automatic lakes delineation scheme is proposed to map the glacial lakes with Landsat Imagery in Himalayas mountains area.The res...
