Background:
The Japanese ALOS PALSAR sensor acquired the image on 1 June 2008 1:24:58 Sydney Time AEST (31/05/2008 15:24:58 UTC; 31/05/2008 23:24:58 Bejing Time). Data were available to download from ERSDAC on 03/06/2008 at 21:41. DInSAR results were uploaded on 04/06/2008 at 08:11.
Interferograms obtained from Paths/ tracks 471, 473 and 476:
DInSAR interferogram - ALOS PALSAR Path 471 (29 Feb - 31 May):
Ground displacement in the radar looking direction - ALOS PALSAR Path 471 (29 Feb - 31 May):
Acknowledgement
We wish to thank the Earth Remote Sensing Data Analysis Center (ERSDAC) for providing ALOS PALSAR data. We also acknowledge the strong support from the International Association of Geodesy Sub-Commission 4.4 "Applications of Satellite & Airborne Imaging Systems" and IAG Consortium for Mine Subsidence Monitoring.
METI and JAXA have the ownership of the ALOS PALSAR original data. The PALSAR Level-1.1 products were produced and distributed to CRC-IS/UNSW by ERSDAC, Japan.
