Part 2/2
Dr. Gianluca Valentino (University of Malta) leads this practical session about monitoring the volcanic deformation at Mount Etna using SAR interferometry (InSAR), with Sentinel-1 data and the ESA SNAP software.
This video includes:
00:00 Intro
00:06 interferogram generation via the SNAP graph builder (including read, enhanced spectral diversity, interferogram, TOPSAR-deburst, write)
04:11 results visualisation
05:00 applying the graph to other sub-swaths
06:35 merging interferograms
13:09 merged interferogram visualisation
14:22 phase unwrapping
16:06 results visualisation
16:55 displacement estimation
20:06 displacement band visualisation and colour manipulation
21:18 terrain correction
23:02 masking the sea and final products visualisation
