> From the perspective of a contributor and editor of OSM data rather
> than technical, I'd certainly endorse storing coastline data
> separately. Currently, it takes forever to get the data uploaded
> in the first place, greatly slows down downloads of an editing area
> of interest when I have no interest in editting the coastline, and
> when I am editting it is extremely fiddly and user-error causing
> when it crosses other data.
> I'd see the advantages as:
> - Gives ability to store more than one coastline set
> - To be able to retrieve it as a separate layer would make
> coastline maintenance much easier.
> - Makes general editting easier
> - Protects it from mistakes when doing general editting,
> which will become important if we encourage "drive by" editing of
> our data by the general public.
> - A good test bed for determining whether general
> separation is a good thing (political boundaries, bus routes,
> specialist POI sets, ...) and for enhancing edit and rendering
> tools to cope.
