Time series "double differential displacement analysis"



Measurement of displacement between 2 points:

The time series graphics are available for horizontal (East-West), vertical (Up-down) and line of sight (ascending and descending) displacement.

The pairs of points are located around differents areas (LagunaMaule , Domuyo , ...).

The buttons above each maps allow to switch between different view: S1 for Sentinel 1 amplitude view, Maps for reliefs view and Earth for satellite view.

* The processing “With Coherence threshold” automatically rejects the interferometric pairs affected by low coherence measured at Laguna del Maule region (LdM). It results that several images may not contribute to time series, typically during the Austral Winter. The processing “Without Coherence threshold” makes uses of all the interferometric pairs, including some that may have very low coherence over the LdM area.
WARNINGS: Applying Coherence restriction (i.e. time series "With Coherence Threshold”) may remove several interferometric pairs, resulting in interferometric pairs or patches of pairs not connected to the whole set of data (see the baseline plot) and hence inaccurate MSBAS inversion (artificial offset or oscillations). Keeping the interferometric pairs with low coherence during the Austral Winter (i.e. time series "Without Coherence Threshold”) may also affect MSBAS inversion (e.g. amplitude under or over estimation, artificial oscillations etc…).
