| PS-Time |
A free program for the
automatic classification of Permanent Scatterers time
series
|
PS-Time provides an automatic
classification of ground displacement time series
obtained by Persistent Scatters Interferometry (PSI).
The program applies a conditional sequence of
statistical tests and classifies each time series into
one of the following target
trends:
- uncorrelated
- linear
- quadratic
- bilinear
- discontinuous with constant velocity
- discontinuous with variable velocity
Each trend describes a different deformation style
associated to slope instability or other ground
deformation processes.
Classified time series enhances radar
interpretation of ground movements, greatly improving the conventional analysis based on the mean
velocity.
