The product was generated by calculating per pixel median of all 12-daily Sentinel-1 coherence image pairs acquired over the study area in the summer (June-August) of 2021. Radar coherence is a measure that is sensitive to surface changes (dunes activity, vegetation, construction). The dunes have low coherence values and appear in dark shades in the provided coherence image mosaic. This product is used to drive the dune distribution map.</SPAN></P></DIV></DIV></DIV> |
