Mineshaft are often outside of the main area of the mine. I already thought about a relation. But AFAIK the site-relation is also just a proposal at the moment. Besides it is quite easy to map a mineshaft, but difficult to map the rest of the mine, if there are no satellite pictures.

Some questions: - Do you think it is better to use a namespaced tag (mineshaft:type) or a normal tag (mineshaft_type)? In the current proposal the first one is used. But looking at other features i think that in this case a normal tag would be better.

Can you give an example? > > If you mean status=disused, I'm not sure how that get around the problem > of ignoring all other keys. Yes, I mean status=*, and I'm aware that it doesn't avoid the problem - however, the problem would have to be solved only once for all possible status values. A check for status will filter out objects with e.g. status=planned, too, even if only construction, disused and abandoned were known when status was introduced. A check for c./d./a.=yes will not filter out planned=yes, thus increasing the required effort for monitoring tagging trends and adapting applications. Therefore, I'd consider a common key an improvement, but of course the problem of ignoring keys would still exist. The problem could only be avoided completely by using things like disused_KEY = VALUE or KEY = disused + disused = VALUE, but the widespread use of disused/...=yes seems to demonstrate that not all mappers like these. The idea was that maybe the common key approach could be some kind of compromise. As I said, though, I don't believe that an attempt to establish an alternative to disused=yes could be successful.

Common Key? Can you give an example? If you mean status=disused, I'm not sure how that get around the problem of ignoring all other keys. railway=station status=disused If status is ignored, this would still display as a functioning station. > Once > applications would have learned about the key, they would have been able > to handle new values immediately. > > I also recommend that, when tags are created in the future, they should > be designed so that they can be ignored unless there are important > reasons for breaking that rule. > > Tobias Knerr > > > ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I also agree that disused is widely used, so it cannot reasonably be ignored anymore, and replacing it with an alternative way of tagging probably is no longer an option. However, I believe that using a common key instead of disused/construction/abandoned/...=yes and distinguishing these using different *values* would have been the better alternative.

The thing is, that there are quite different types of quarries, dependant on what you are after. This is an example for lignite mining in Germany, where you usually have huge areas and equipment: http://upload.wikimedia.org/wikipedia/commons/9/9a/Tagebau_Garzweiler_Panorama_2005.jpg actually there you are after lignite that is quite profund (up to 100 m) whilst this is what I would expect from quarry: http://upload.wikimedia.org/wikipedia/commons/6/65/Quarry.jpg http://upload.wikimedia.org/wikipedia/commons/6/60/Lobejun1.JPG http://upload.wikimedia.org/wikipedia/commons/5/50/Cararra-Steinbruch.JPG here they are getting plates and cubes, mostly not too profund, and generally much smaller areas, but the material is quite hard. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

They might call the building "the cafe" even if its no longer a cafe "in use". So this is what the mapper *may* wanted to express. While I don't think the combination is well done, it but could well have its reasons. However, This obviously doesn't work pretty well in the 4th dimension, if you want to tag: this once was a cafe, before that a pub, before a bakery and before that a police_station. Another even simpler problem, if a node is tagged: shop=bakery amenity=police_station disused=yes disused refers to shop or amenity now?

Okay, but what if the tag is "man_made=mineshaft"? Is it safe to ignore the "disused=yes" tag then? I don't see why not. It's not like "man_made=mineshaft" means you can grab a pickaxe and go head for it. A mineshaft defaults to *not* being accessible to the public. Whereas a parking lot defaults to being *accessible* to the public (in fact, that's even in the definition, though the definition is somewhat ruined with the weasel-word "Generally"). Bottom line, is "man_made=mineshaft" a tag to represent the physical presence of a mineshaft, or is it a tag to represent the use of a mineshaft in mining? If the former, disused=yes is fine. If the latter, it isn't. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Because tags like disused=yes conflict with a general principle in OSM: We don't have a fixed set of tags and mappers can invent and use their own tags, so it should be possible for software to ignore tags it doesn't know without causing problems. If I don't support distinguishing between different variants of amenity=parking, I just ignore parking=* tags entirely, and while the result is less useful, it's still correct. If I don't support disused features, I can just ignore disused=yes tags ... no wait, I can't. Of course, in order to make mapping convenient, it's sometimes necessary to break that concept (with access tags, for example), and probably we won't be able to get rid of disused/abandoned/construction/planned/proposed/etc anymore.

Disused railway, sure. Disused building, no problem. Disused quarry, yes. But disused cafe? A cafe is a building, or part of a building, which is *used* as a cafe. The use is part of the definition.

Headframe is the more correct term. A headframe is the structural frame above an underground mine shaft (see Wikipedia). Usually winding shafts have such a headframe, air shafts do not. A pit head could also be a building with an enclosed headframe. But the intention of this tag is to express if the headframe is visible, because it is a prominent point of reference.

Re: [OSM-talk] [tagging] Feature Proposal - RFC - (man_made=mineshaft)
I worried that the use of language might prove to be confusing and the the buildings associated with a mine should have a separate tag. 1. Mineshaft may exist but we are going to be mapping the location mine entrances, not the tunnel leading away from the mine entrance. In the future someone may want to map the 'way' that the mineshaft follows especially if its a horizontal tunnel going into a hillside 2. What we want to locate, or map, are mine entrances. Mine entrances to are mostly small and most go horizontally into hillsides. http://upload.wikimedia.org/wikipedia/commons/3/35/Mine_entrance.jpg I assume most are too small to map as an area in OSM. They would have to be mapped as a node. 3. There are plans to supply info on structures associated with mines as part of the tag, notably the Pit Head. I think this could be confusing and people would map the outline of the Pit Head structure and tag it as a 'mineshaft'. The Pit Head should be mapped separately as a building and this should be made clear. 4. The term Headframe is used to describe a Pit Head, which is confusing. More problems with language use. Pit Head appears to be the correct term for the building or structure.

IMO they are something completly different. http://wiki.openstreetmap.org/wiki/Proposed_features/Surface_Mining The intention of this proposal is to tag the most important and most visible part of a mine - not the other parts, which are just normal buildings. The area of the mine can be tagged with landuse=industrial. > > and some mineshafts have winding gear on headframes > and lots of other things Having winding gears is the main purpose of a headframe IMO. lesi ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

A Processing Plant, will produce one resource and take in a different one, I agree standardizing on resource might be a good idea but we might need resource_output and resource_input or somthing Peter. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
