Copernicus Sentinel-2 helps generate "game changing" intertidal habitat maps

Intertidal habitats can change rapidly, not just in spatial extent but also in vegetation type and cover. Newly created coastal managed realignment sites are a prime example where channels migrate and the vegetation changes from terrestrial to mud flats and saltmarshes.

Monitoring these changes is difficult due to their highly dynamic behaviour, inaccessible nature and risk of ecological damage caused by field work. Aerial photography is costly and thus usually restricted to once a year at best-however, Copernicus Sentinel data are changing things.

Now with the Sentinel satellites of the European Union's Copernicus Programme, these systems can potentially be used to observe a site every few days with images that have a spatial resolution down to 10 m.
