Title: SAR lines computed over the River Dart estuary
Description: This image shows a total of 907 lines (452 from ascending Copernicus Sentinel-1 acquisitions and 455 from descending ones) over the River Dart estuary, featuring the dynamics of the estuary between 2014 and 2019, where SAR lines computed split between ascending and descending passes.
The mismatch between both blue and red lines indicates how the different observation geometries can "see" diverse features of the estuary. Waterlines can be retrieved when there is line of sight of the water-sand boundary and vegetation lines when the sand backscatter is shadowed.
