Abstract
Dense continuously-operating networks of GPS receivers
(CGPS) have been established in many parts of the world
in order to monitor ground deformation due to
earthquakes and other activities. However, it has been
found that the CGPS is still NOT dense enough to
monitor some phenomena, e.g. volcano and ground
subsidence due to mining. Therefore the authors propose
to combine GPS with radar interferometry (InSAR) and
GIS so that CGPS can monitor small scale deformation as
well. The methodology is to use CGPS to estimate the
differential tropospheric delays and apply these
estimations as corrections to the radar interferometric
results in order to ensure sub-centimetre accuracy. The
corrected InSAR results are exported to the GIS so that
the ground deformation can be interpreted along with
other spatial information such as aerial photos and mine
plans. Data from both the SCIGN and GEONET have
been employed to test the tropospheric estimation process.
InSAR results for monitoring subsidence due to
underground mining in an Australian region have been
interpreted with the aid of the GIS.
