I've tagged about five or six boat ramps about the place, and it wasn't until I read these emails that I even considered putting it on just the a single node.

Anyhow, I've changed the tagging to show highway=service to the approximate high water mark, then leisure=slipway for the couple of hundred metres of way from there down to the present water level. And I've tagged the joining node as leisure=slipway as well. If I want to draw attention to the fact that the slipway tag needs to apply to significantly-long ways as well as to nodes, where's the appropriate place to do that?

If you need to break the current specification to do so, then make a note on the wiki page. Tagging it highway=service seems wrong. Service roads do not go underwater. So, where should it terminate, before the water? Or at a junction with the polygon? Neither of these choices is really suitable, so leading a way into the water seems the best option to me. Also, from the wiki for 'service': Generally for access to a building, motorway service station, beach, campsite, industrial estate, business park, etc.. This doesnt sound wrong to me, if a service road can lead to a beach or campsite, why not to a boatramp? The tagging system is supposed to be flexible and updated to reflect changing requirements, after all. I thought the tagging system was meant to be consistent, before being flexible. If everyone tags boatramps in their own 'flexible' way, how is any renderer supposed to know what to do, for every possible variant? I believe it should be discussed in here, and the general consensus should be applied when tagging, rather than everyone going off with their own idea.

That was my initial thinking. When I tagged it like that, it didn't render of course. And I thought it important for a boat ramp to show up. If only highway=ford rendered. But that's not right for a boat ramp either. Do you mean make a note on the Australian Tagging Guidelines and tag the way as leisure=slipway? As a traffic way, it really should have a highway=* tag, shouldn't it? John H ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

From the leisure=slipway wiki page: A slipway is a ramp into the water for launching a boat. In Australia they are referred to as boat ramps. In the US they are often referred to as boat landings as well as boat ramps. They are typically simply a concrete ramp at the end of an access road or track into the water. The boat owner backs a vehicle with a boat trailer down the ramp until the trailer is in the water and floats the boat off. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
Re: [talk-au] Boat ramp
Hi John, Ive been tagging a few boatramps lately, and your suggestion is basically exactly what Ive been doing, but I have also wondered if it is the best method, and had a few questions. Firstly, leisure=slipway works fine for most cases of boatramps, but some boatramps arent 'leisure', for example a water-police or navy boat ramp or a boat ramp setup near a dry dock. These ramps are still slipway's but dont fit the leisure category. Maybe an access= tag or something might be appropriate. Secondly, Ive wondered (like you), how exactly to map them. Should they be mapped right to the waters edge, or should they continue down past the waterline, the same way the actual ramp does? Im aware there are issues with people attaching ways to polygon/relations, so Ive been extending the way over the polygon and into the waterway. Ive been mapping a few ramps around Canberra, and have come across a few different uses. Ive also noticed some areas have rowing pontoons setup in the lake, which are the same as a boat ramp, but they run at ground level while the boatramp disappears under the water. These arent really slipways, but what else is appropriate? Some sort of sport=rowing amenity=pontoon or something, comes to mind.

The leisure=slipway tag is meant to apply to nodes, not ways. Inland impoundments can have long boat ramps because the water levels can vary so much. This link shows the length of ramp that's currently exposed at Lake Burrinjuck: http://www.osm.org/?lat=-34.982064lon=148.624566zoom=18 I've also tagged the node at the high water mark as leisure=slipway.
