Traditional digital elevation model (DEM) is extracted from a pair of stereo images with a wide baseline. But wide baselines may increase the likelihood of occlusion problems and the difficulties of image matching. In this work, a method that generates DEM from multispectral images with very narrow baseline...

Hulunbuir Grassland is one of the world famous steppe. Along with global climate change, the beautiful mosaic landscape of grassland-wetland-desert is getting unstable under huge demographic and economic growth pressures. From 2000 to 2010, the total area of water reduced by 396.52 km2 grassland by 234.71...
