How do I tag the area of a commercial harbour (i.e. including the service roads, parking, storage areas, container terminals, ferry terminals, shipyards and so on)? Is it all a single “landuse=industrial”?
Should passenger ferry areas (including their approach area, carpark, etc.) be tagged separately?
I notice that “leisure=marina” can be distinguished, which is nice. Should that be used on an area including the actual water of the harbour, or the piers and land area around it?
I notice someone tagged a container terminal in the port of Hamburg as “landuse=retail”, which strikes me as an odd choice. http://openstreetmap.org/?lat=53.5349&lon=9.9479&zoom=15&layers=B000FTF
I was going to trace some of the areas in Piraeus harbour http://openstreetmap.org/?lat=37.94337&lon=23.62918&zoom=15&layers=B000FTF (from the Yahoo images, which are very good for this area)
