| Mapping
of surface and structural displacements on the ground can be
achieved with three distinct techniques of SAR interferometry.
Each of these is suited to particular displacement mapping applications
and provides alternative end-products. Click on the links below
for more information. |
 |
Conventional
Imaging InSAR |
| Differential
interferograms can provide sub-centimetric displacement fields
over wide areas and spanning timescales from several weeks to a
few years. |
|
|
|
 |
Persistent
Scatterer InSAR (PSI) |
| For
long-term surface rate of motion mapping, plus millimetric displacement
time-series of individual ground points. |
|
|
 |
Corner
Reflector InSAR (CRInSAR) |
| Ideally
used for measuring and monitoring displacements of specific structures,
e.g. water reservoirs, dams, bridges and other buildings. |
