Abstract

Updated informat ion on flood mapping that recently occurred in South Sulawesi is an important necessit y for site policymakers. Mapping of flood area during or soon after the flooding event is tremendous hardwork. However, using active-remote sensing namely InSAR (Interferometric Synthetic Aperture Radar) technique can overcome these limitatations. To achieve it, at least two radar images have to be obtained which is 1 image before and 1 image during/after a flood event. We selected 2 images Sentinel1A GRDH data for the same pass direct ion and the same time acquisitit ion with polarizat ion VH (Vertical-Horizontal), 12 days of temporal baseline. The images were then processed by SNAP Toolbox. The results show that Sent inel-1A succeeded in detecting and monitoring flood event, where inundated of water in Tallo River is visible in VH polarization.
