Abstract

The spatiotemporal distribution of subsidence at Palangkaraya, Central Kalimantan, Indonesia, was studied by a time-series analysis of PALSAR data obtained over 26 passes of ALOS over the study area. This area consists mainly of peatland and tends to subside because of climate change, i.e., global warming. Applying a moving weighted window to the stacking of a DinSAR dataset, each of which was calibrated using stable points in the image, we quantitatively captured subsidence phenomena and found that the area has subsided at an average rate of 2.02 cm/yr.
