Synthetic aperture radar interferometry (InSAR) utilizes phase differences between two or more
SAR observations for deriving digital elevation models (DEMs) of the earth's surface, and
estimating surface deformation due to oil, water, and natural gas extraction, and detecting
displacements of glaciers, monitoring low deformation rates associated with mining practices
over a large spatial extent. This half-day workshop introduces the principles and applications of
InSAR, DInSAR and TimeSAR, and provides in-depth discussions on the current challenges in
the technique. New developments in the topics of InSAR stacking, time-series analysis of
linear/non-linear surface deformation and polarimetric InSAR, and amplitude based subpixel
offset tracking will be reviewed with results from ongoing projects and recent publications.
Interferometric data processing strategies with specific applications in DEM generation,
measuring building sinking, and monitoring earthquake deformation, detecting subsidence from
water withdrawal, underground mining, estimating tree height, and the conjunctive use of GPS
with timeSAR will be discussed.
Presenter biography
Dr. Wasit Wulamu (aka Abduwasit Ghulam in publications) is an Assistant Professor with the
Center for Sustainability at Saint Louis University (SLU). He received his B.S. in Physical
Geography and M.S. in Cartography & GIS from Xinjiang University in 1998 and 2001,
respectively, and earned his Ph.D. in Cartography & GIS from Peking University in 2006. After
graduated from Peking University, he joined the Image Sciences, Computer Sciences and
Remote Sensing Laboratory (LSIIT) UMR 7005 at University of Strasbourg (also known as
University of Louis Pasteur), France as a Post Doctoral Research Associate in 2006. Prior to
joining to the Center for Sustainability, Dr. Wulamu held Assistant Research Professor position
in the Department of Earth & Atmospheric Sciences at SLU.
He is currently teaching graduate and undergraduate courses in InSAR, Microwave Remote
Sensing at Saint Louis University, USA, and has presented a number of papers and workshops in
InSAR at international conferences (e.g.,) IGARSS 2011 and EOROSA 2014. His research
1
focuses on 1) InSAR applications in ecosystem monitoring, crustal deformation, Geohazards,
and 2) Sustainable agriculture under changing climate. Dr. Wulamu has authored over 50 peerreviewed journal publications, one book chapter, and presented more than 50 conference papers
and workshops.
