Description of Glacial Lake Inventory of Bhutan using ALOS (Daichi) Data

This document aim to develop and publish the glacial lake inventory in the Bhutan Himalayas using optical instruments onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”), which was launched on January 24, 2006. The Glacial Lake Outburst Flood (GLOF) is exposing to a risk for peoples living in downstream regions. The glacial lake inventory is newly developing using ALOS data under “Study on GLOFs in the Bhutan Himalayas” project supported by Japan Science and Technology Agency (JST) and Japan International Cooperation Agency (JICA) under the “Science and Technology Research Partnership for Sustainable Development (SATREPS)”. The field survey has been conducted in 2010, and the location accuracy of 9.5m (average) and 11.9m (RMS) has been achieved at a lake in the inventory. We are cordially announcing public release of “Glacial Lake Inventory of Bhutan using ALOS Data” (evaluation version).
