This study aims to evaluate the capability of D-InSAR technique using large perpendicular and temporal baselines for measuring the ground displacement caused by tectonic movement and anthropogenic activity in the Bandung basin, West Java, Indonesia. Small baseline subset (SBAS) D-InSAR technique is adopted to clarify the spatio-temporal displacement pattern of the basin, and its accuracy is verified statistically using Pearson’s correlation coefficient and root-mean-square error by comparing the estimated displacements with the displacement data by GPS. The results highlight two displacement patterns in the basin: anthropogenic-caused subsidence in the middle urban area and tectonic-caused uplift in the northern and southern parts around the faults.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]ALOS PALSAR,Anthropogenic activity,Differential interferometric synthetic aperture radars,Displacement patterns,Pearson’s correlation coefficients,Root mean square errors,Small baseline subsets,Tectonic movements[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]ALOS PALSAR,Small baseline subset (SBAS),subsidence,tectonic movement[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/IGARSS.2019.8898328[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
