Production of DEM for Analysis of Microtopographical Features around Balkhash Lake by ALOS PRISM Data

抄録

The high accuracy DEM was produced from the ALOS/PRISM stereo pair data for the purpose of investigation of the fluctuation in the water level and describing of the past lake area of Balkhash Lake. The characteristics and accuracy of the produced DEM were investigated through the comparative analysis of the SRTM DEM and field survey data. Furthermore, the possibility of the micro-topographical features distribution along the lake shore line was investigated.
