ALOS-2 ScanSAR RGB Change Map

/in /by

Three PALSAR-2 ScanSAR images were used for disaster response: Pre-seismic: 2025.01.16 & 2025.02.19 Co-seismic: 2025.03.30 Orbit and angle: Descending, 39.02 degree Normalized pre-seismic coherence – co-seismic coherence represents “red” channel. Normalized co-seismic coherence – pre-seismic coherence represents “green” channel. Averaged pre-seismic and co-seismic coherence represents “blue” channel. Link.Kmz

ALOS-2 ScanSAR Damage Proxy Map

Three PALSAR-2 ScanSAR images were used for disaster response: Pre-seismic: 2025.01.16 & 2025.02.19 Co-seismic: 2025.03.30 Orbit and angle: Descending, 39.02 degree Coherence estimation was performed for pre-seismic and co-seismic pairs at 20 m pixel spacing. Using Jenks classification, the results were categorized as follows: Blue pixels: Likely “no change” (stable areas) Yellow and orange pixels: […]

Damage proxy map following M 7.7 Myanmar earthquake

/in /by

We have processed the Sentinel-1 images from ascending orbits over Myanmar to generate urban damage maps in heavily damaged areas like Mandalay and Naypyidaw. If you like to see the whole possibly damaged areas in Google Earth, here is the *.kmz file: https://drive.google.com/file/d/1_vuOM4qQh4W4L81RdF9_IBxA5ZLzxU2i/view PDF link

Initial Damage Assessment of the M 7.7 Myanmar Earthquake for Bangkok, Thailand

/in /by

Following the devastating M 7.7 earthquake in Myanmar, our team rapidly generated the first damage map using ALOS-2 PALSAR-2 satellite data. Thanks to timely ALOS-2 observations over Bangkok, we were able to conduct preliminary damage analysis. The coherence difference products serve as critical indicators of post-event changes. The larger the coherence difference, the more change was observed after the earthquake. PDF link
