Multi-resolution synergy of optical, thermal and SAR data for mapping of wetlands and permafrost on Tibetan Plateau
Potential of various techniques that utilize data from multiple sensors for mapping of wetlands on Tibetan Plateau have been evaluated. Optical and thermal infrared bands from Landsat and Corona together with SAR data from TerraSAR-X, ALOS/PALSAR have been used. Closed basin of Nam Co (‘Co’ means la...
