Monitoring of Peatland Surface Height Variability using DInSAR Analysis on ALOS-2 PALSAR Data and Field Observation of Ground Water/Surface Level Data

摘要

Peatland surface height variability has been observed using Differential SAR Interferometry (DInSAR) analysis ofALOS-2 PALSAR data and the ground water/surface level (the GWL/GSL) data analysis during 2014/8/28-2017/9/20 period.Study area is chosen at peatland area near Palangka Raya City, Central Kalimantan, Indonesia. The observation result shows thatthe variability of peatland surface height is affected by fluctuation of the ground water level and successfully observed byDInSAR analysis. The difference of peatland surface height variability between DInSAR analysis of high-resolution mode ofALOS-2 SM2 mode data and the GSL data is about ±0.23~2.2cm.
