Yes, I did use the heightmap of the real North Caicos! I also left the real life name, but of course the background story I made, and the network layout, are the fictional part of this map

Just how fictional is this, really? The shape of the land mass looks an awful lot like https://www.google.com/maps/place/North+Caicos/

Thanks Annie!! And yes, I already know about BonBonB ;)

Lovely map, looks really nice and very playable. Thank you for your work, well done.
