Coastlines

How long does it take for a coastline edit to show up in the rendering?

Coastlines are a special case in OSM rendering, a set of coastline shapefiles are generated, AFAIK, weekly. This catches most users out at some point in time. :slight_smile:

Depends on the renderer

Currently, it can take weeks for your coastline changes to show up on the mapnik layer. It’s less than optimal, I’d say.
