Overview¶
The Coregistered Single-Look Complex from Sentinel-1 (CSLC-S1) product provides interferometric-ready SAR data derived from Sentinel-1 SLC acquisitions. CSLC-S1 is the foundational Level-2 input for higher-level OPERA surface-displacement processing (DISP-S1) and supports general interferometric SAR (InSAR) analysis.
