[OSM-talk] Harbours (was: New osmarender markings...)

Hi,

I recently found one such feature (natural=beach) and simply added it
to the relevant style sheets, and now it is rendered. Easy ;-)

(Not so easy: How to tag beaches? Many in the planet file are just
nodes, amenity-like, which is ok, but I wanted to have the whole sandy
area depicted on the map and so I chose to draw an area that shares
segments with the coastline way.)

While we're at it, I would love some advanced guidance on harbours. I
don't know a lot about boats and stuff. A typical small harbour, to
me, consists of a breakwater wall, and behind it a lot of water and a
lot of concrete giving room for boats to anchor in an orderly fashion;
there may be some special places where you can get boats in and out of
the water (slipways?), some places where people and/or cars can get
onto a larger vessel (piers?), and usually a lot of (often wooden)
footbridges to reach the smaller boats.

All this is often quite easy to locate and you can even walk most
places with your GPS (even on the breakwater wall), but how would I
sensibly tag all this. Just the wall and a big area behind it? I could
imagine that harbour users would like details. I saw that there's a
proposed tag "man_made=harbour_wall" or so; I am unsure whether only the
wall that protects the harbour from the sea outside is the harbour
wall, or whether it is still a harbour wall if it is between the
harbour basin and the land. 

I could of course make everything up myself but I'd really love one of
our seamen to tell us what we would sensibly tag about a harbour, and
how you would expect it to look on a generic (non seafarer-specific)
map.

Maybe somebody has already meticuously mapped a harbour somewhere?

Bye
Frederik
