Supposing I wanted to undertake a project to solve this class of problem, either using layers or areas or something e3lse. I imagine the project would have a number of peices, since it affects the database, editors, rendering tools, and heaven knows what else. On which list would we flesh out

Yes, in that small fraction of cases there would be duplication of positional data. But in some cases where you think this is the case, it might actually not be. My county border was defined by a river. Now part of the river is a reservoir and the other part has shifted over time and through floods

Thanks everyone for the feedback on the redesign effort. Development work on the redesign is in a lull right now due to competing priorities, but we hope to get back to it and continue refining the design in the near future, and we'll be taking your comments here and on the pull request into accou

Another popular view is that these are problems for the renderer/editor, not intrinsic issues with the data. Tag as you see fit and the renderers/editors will catch up! The fact that coastlines are difficult to maintain with the current toolset is not an argument to not have them in OSM. Back

Nick, this can be done for admin boundaries as well. Would you advocate removing them from OSM as well? The change to the size of the planet file if timezones are included is absolutely microscopic in the big scheme of things. There are clearly many shades of grey. It's a question of where to dr

I'd go the other way and abolish Winter Time. ;-) No DST = dark summer evenings. Not nice! Going on topic, not sure if something like time zones belongs in OSM. Would it not be better to use a more specialised web service to look up time zones for a given lat/lon? I'd prefer to minimise overloa
