ID: polygon ID
area: area of interest, the area seaward of the coastal road/unintended coastal defence structure (named: "coastal zone"), and the area landward of the coastal road, occuppied by active and abandoned aquaculture ponds ("pond zone")
year: the acquisition year of the satellite image that was used to digitize the polygon

surface area: surface area of the polygon in m^2
surface area ha: surface area of the polygon in hectares.

mangrove polygons:
Id: Id
gebied: Dutch for "area", initially this was purely based on winddirections: noordwest (Northwest), zuidoost (Southeast). We later renamed these to coastal zone (Northwest) and pond zone (Southeast).
Type: vegetation type: aangelegd (planted mangrove vegetation), natuurlijk (natural mangrove vegetation), associate (originally categorized as mangrove associates, but upon field validation renamed to: terrestrial vegetation)
