ACKNOWLEDGEMENTS 
This research work is supported by the Cooperative Research 
Centre for Spatial Information (CRC-SI) through Project 4.09, 
whose activities are funded by the Australian Commonwealth’s 
Cooperative Research Centres Programme. The authors wish to 
thank the European Space Agency (ESA) for providing the 
ENVISAT data. ALOS interferograms were processed under 
CRC-SI project 4.09, including material copyright METI and 
JAXA (2006-2008) L-l.l product: produced by ERSDAC. 
METI and JAXA have the ownership of the PALSAR original 
data. ERSDAC produced and distributed the PALSAR L-l.l 
product. The PALSAR L-l.l products were distributed to the 
IAG Consortium for Mining Subsidence Monitoring. The 
authors are grateful to ERSDAC for their support of the 
consortium.
