2.2.1. Sentinel-1 Data

Sentinel-1 (S1) Ground Range Detected (GRD) products in dual-polarization mode (VV + VH) were used in this research (Table 1). Data were downloaded from the European Space Agency (ESA) Data Hub and, as a GRD product, imagery has already been detected, multi-looked, and projected to ground range using an Earth ellipsoid model [37]. Additionally, in ESA SNAP software, data were calibrated to sigma naught (σ0) backscatter intensities, speckle filtered using Lee filter [38], and terrain-correction was made using the shuttle radar topography mission (SRTM) one-arcsecond tiles.
