Yeah! The whole atoll. I have never been there though. I see you quite a lot in object history around here, I think you did stuff like added addresses and points of interest? I try to not change too much about points of interest because I really have no clue. Sometimes I space the nodes a bit more and place female/male bathrooms next to each other if they're all seemingly randomly in some building or I put POI node tags onto the building itself if it's just one POI. Another example is a pavilion with bathrooms and some barbecue thing, I put the barbecue POI onto a smaller building to the side which seems like a tent ... stuff like that. Or on Ebja/Ebeye/Epja, I noticed there's this same long building design with two small round buildings on each end, I kept adding those round buildings even where I couldn't see more than a smudge. I changed quite some island and passage names too, the source should be on all place=island nodes. Some map from the 80's or so provided by a cool radio guy. Even there it's already 2-3 different names for each Island, very confusing. But should be more accurate than those GNIS imported name nodes with coordinates rounded like 167.73333, off by Kilometers and somebody tried matching them to islands. I think I deleted all GNIS stuff except for Roi-Namur and Kwaj and the atoll. Not sure if we need it in OSM, I'll contact the people who originally added it and consult the wiki page on GNIS.

I'm done, and fair enough, there's quite a lot of sand banks. Will use natural=shoal.

natural=shoal

It's obviously not sand, at least not sand that ever shows up over the water, I'll change it back to natural=reef when I'll refine it today. It's not 100% reef but look at other atolls in the Marshall Islands, it's also a border of the areas of the atoll where the water is very shallow. At least that's how it's used in the marshall islands.
