COUNTRY
SECTOR
TYPE OF DATA
SAR interferograms, persistent scatterer velocity maps
COPERNICUS DATA
Sentinel-1 IW dual-polarization (VV + VH) Level-1 SLC products
SHORT SUMMARY
Persistent Scatterer Interferometry (PSI) was applied to Sentinel-1 SAR time-series (IW mode, 20 m resolution) using SNAP + StaMPS to detect subsidence rates in Lagos’s main port expansion zones. Results showed localized subsidence between –1 mm/yr and –6 mm/yr, crucial for port authority flood-risk assessments and maintenance planning. mdpi.com
