I edited the coastline of the Indonesian island Malenge. Unfortunately the new better coasline is only visible to me in iD editor but not for the public. Why? What can I do to publish it. The other objects I added like paths and buildings are visible to the public.
You just have to wait. The coastline is a special beast. Unlike the other features that are normally rendered within minutes, the coastline is updated with a much lower frequency. One of the reasons is that it is only updated when no problems are found in the coastline data. So if someone broke a coastline in another part of the world, rendering is delayed.
This check is done because a broken coastline would render everything blue.
You can find some information about that on https://wiki.openstreetmap.org/wiki/Coastline
Coastline is critical data to the rendering process, so updates are delayed to avoid problems.
See section “Rendering in Standard tile layer on openstreetmap.org” in https://wiki.openstreetmap.org/wiki/Coastline
The coastline data was last updated May 25. You can check it here http://openstreetmapdata.com/data/land-polygons and http://tile.openstreetmap.org/cgi-bin/debug
Tack on question::
How detailed is too detailed for coastline/riverbank/lake tracing? So many nooks and crannies… the OCD part of me just going nuts!
