some time ago we had a guy from a British Island, dmgroom_ct, who contributed a huge amount of work on both Pacific and Caribbean coast. huge work, and we chatted on the https://t.me/Comunidad_OSM_Panama Telegram Group.
the Pacific coast in Panamá has some 5m sea height tidal difference. the aerial pictures we have may have been taken at any tide level, we don’t know and we need to interpret it. the land which remains exposed may be rock, or mud, or sand, or it may have mangrove cover. whichever the case, it’s natural=wetland, wetland=tidalflat, it’s not part of the land mass.
in November 2020 the #adt (Apple Data Team) came to review all sort of things, when we realized they had been busy in the area, they assured us “las líneas costeras parecen bien a nuestro equipo” (the coast lines look good to us). however, I’m now seeing they “corrected” the contributions by dmgroom_ct.
Andrews says, very correctly, that it’s only me complaining about their edits, that’s true. nobody else reviews anything here in Panamá, except possibly https://www.openstreetmap.org/user/gscholz and https://www.openstreetmap.org/user/dmgroom_ct. local people will not enter in a “discussion”, because that’s simply a very bad thing to do here, “discussing” sounding like arguing aka fighting.
I’ve reviewed two points where the #adt has altered the coastline, and in both cases they didn’t consider the tide. one they already reverted, but I’m afraid their whole contributions on the Pacific side should be rolled back. if they had done this three years ago, they would have refined some very rough initial import from satellite data. but last November they messed up the quite accurate contributions by dmgroom_ct.
