IPTA - Interferometric Point Target Analysis for persistent scatterers InSAR

DESCRIPTION

he Interferometric  point Target Analysis (IPTA) package is a collection of tools to exploit the temporal and spatial characteristics of interferometric signatures collected from point targets to accurately map surface deformation histories, terrain heights, and relative atmospheric path delays. The analysis can be summarized as an iterative improvement of the model parameters to achieve an optimal match to the observed interferometric phases. The analysis is done for a selected list of points which correspond to point target candidates, which dramatically improves efficiency and storage requirements

 

City of Rhodes (Greece): linear velocity map obtained by PSI processing of 28 ENVISAT ASAR scenes over Rhodes (2002-2010). The velocities were obtained from the Line of Sight displacement assuming that the displacement is vertical. Background: averaged SAR intensity image. – Processed using the GAMMA-IPTA™ software
