The delineation of shifting cultivation landscapes using remote sensing in mountainous regions is challenging. On the one hand, there are difficulties related to the distinction of forest and fallow forest classes as occurring in a shifting cultivation landscape in mountainous regions. On the other hand, the dynamic nature of the shifting cultivation system poses problems to the delineation of ...

This paper addresses the land cover classification capabilities of multi-temporal synthetic aperture radar (SAR) data and optical data fusion based on Bayesian approach. Multi-temporal SAR data were used to extract average backscattering coefficient, backscatter temporal variability and long-term coherence while the reflectance values were calculated using the optical data. Grey Level Cooccurre...

The ALOS satellite was launched successfully on January 26, 2006. It has three remotesensing instruments: the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) for digital elevation mapping, the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) for precise land coverage observation, and the Phased Array type L-band Synthetic Aperture Radar (PALSAR) for day-and-night...

The objectives of this study are to validate generated Digital Surface Models (DSMs) by PRISM onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”) in snow and glacier regions to contribute to the evaluation of potential Glacial Lake Outburst Floods (GLOFs) and their mitigation in the Bhutan Himalaya. Glacial lake inventory will also be generated to investigate the expansion ...
