The mangroves

The islands in the lagoon in front of Yas Links, and the flats along the north-west shore, are mangrove forest standing in shallow water. OpenStreetMap draws those islands as sea, so at first the map had none. I found the forest in satellite data, ESA’s land cover map and Sentinel-2 pictures from August and September, and painted it over the water: a dark canopy of crowns about 7 metres across, lighter at the edges where young trees and saltmarsh thin out, with the tidal creeks left open. At night nothing lights them but the moon.
