I'm fairly new to OSM but I am interested in adding the data on and around
inland waterways in the UK as I have a boat and find that the detail on Bing
and Google maps are very poor for showing how to get to local amenities on foot
from a waterway. I am thoroughly confused however how best to tag water spaces
built for the mooring of boats. Historically, in the late 1700's early 1800's,
when such places were constructed for freight they were variously called docks,
basins or ports and were used for the loading and unloading of boats, or
trans-shipment between boats, as well as the mooring of boats awaiting for
orders. Today, of course, the majority of these are used for mooring leisure
boats and have been joined by new constructions which are usually called
marinas. Most of these are scooped out of farmland although some leverage
existing flooded quarries.
Potlatch offers an icon for tagging marinas but the tag it applies is
leisure=marina which according to the wiki should be used to cover the full
extent of facilities associated with a marina including any land-based
services. I find it regularly applied just to the water space with another tag
to make sure it renders as water; often waterway=canal which renders as a line
on some renderers even though it is a drawn as a polygon.
I've also found inland marinas tagged waterway=dock which broadly matches the
wiki description if you substitute "boats" for "ships" in the description.
Although it doesn't specifically mention mooring, which would also be a
function inherently supported by a ship dock as well as a boat dock. Many
marinas include some kind of slipway or dry-dock for boat repair.
I've also are also some marinas tagged as landuse=basin, but I notice that
landuse=reservoir has been deprecated to be replaced by
natural=water+water=reservoir. On this basis, why hasn't landuse=basin
waterway=dock been similarly deprecated?
I have to say I find natural=water counter intuitive for man-made structures
that contain water, but if this is the way forward I'll go with the flow.
In which case a marina should be tagged natural=water, but then water =?
marina,mooring,dock, basin,port? Or doesn't it matter? Is it good to capture
the historical usage? I assume boat=yes could also be added to indicate it a
navigable water space?
Advice please!//Mike
