Key Features
Reservoir monitoring, Los Angeles (USA)
Automated
Sentinel-1 epochs
management for PS
Stage 1:
Run SNAPPING IFG
(interferometric stack assembly)
A processing job to set-up
or update the interferometric
stack
Stage 2:
Monitor SNAPPING IFG-D
(interferometric stack delivery)
A delivery pipeline generating
the differential interferograms
Stage 3:
Run SNAPPING PSI
(persistent scatterers interferometry)
A processing job channeling
the interferometric stack as full
input set for time series analysis
Finally
Visualise, analyse, share, download
the time series results
A multi-temporal
interferometric service
Allowing to generate and update
differential interferograms as part of an
interferometric stack
Producing measurements
of surface displacements, using
Persistent Scatterers Interferometry (PSI)
Based on the software packages
