Re: [Tagging] Optical telecomunication cable tagging
Hi Dave, I agree for location=* tag and it should be used in every domain of knowledge in OSM since it is really a common tag. Regarding buried telecommunication cables, location=underground suits my needs. But my point was to know if communication=* is the best primary tag to map such cables. Telecommunications aren't well developed in OSM, only submarines cables were added to map years ago and I've never seen any terrestrial cables or markers plotted since. Maybe it's the time to think about it, isn't it ? A telecommunication cable is a bit foggy : there are not only cables, but markers, underground rooms, junctions, etc. Like pipelines or power for instance. The only communication tags I know are : - tower:type=communication, mainly for cellular mobile communication towers - communication=line, for submarines cables. What else ? *François Lacombe* francois dot lacombe At telecom-bretagne dot eu http://www.infos-reseaux.com 2014-03-04 1:14 GMT+01:00 Dave Swarthout daveswarth...@gmail.com: I came across this tag while working on adjusting the route of the Trans-Alaska Pipeline. The location tag tells whether a feature is above or below ground: http://wiki.openstreetmap.org/wiki/Key:location I think location is a poor term for this but it is in use and is in the Wiki. Together, Taginfo says the two tags location=overground (13,888) and location=underground (19,338) make up almost 35K uses.

Re: [Tagging] Optical telecomunication cable tagging
I definitely agree with you Martin. I said communication=line is for submarine cables since there are only submarine cables identified with it. But we should start mapping terrestrial cables when we see markers like me last weekend. But what should that generic tag be ?

Being in charge of GIS projects for the fiber network of a major telecommunication operator, my opinion is that Openstreetmap will never achieve any useful view of optical networks: those cables are everywhere but their path is usually not visible from public right of ways. I contribute to the mapping of high-voltage lines, which are major landmarks. I support the mapping of cabinets, which are minor urban landmarks. I understand that some may be willing to map telecommunications chambers, whose metal opening is visible on the surface. But spare yourself the pain of mapping underground cables - I guarantee it is a hopeless and useless endeavour. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] Optical telecomunication cable tagging
Just consider we are talking about pipelines here, optical pipelines which are going out of any urban area most of the time. Indeed there's no point of mapping MAN networks in OSM since editing tools aren't able to distinguish such micro-data from the rest of the dataset yet. Like gas oil pipelines, we can map markers and cables too, regarding long distance links. We won't be able to map optical circuits or L2 links and that's not the goal. Let's try to give a map of bare infrastructure before everyone forget about it (and before everyone dig in it 'cause no one can inform them of what is under their feet). FT/TRN markers are disappearing in France, get stolen or buried in fields borders and Jean-Marc's underwater ducts get sometimes forgotten by French navigable ways managers (even if they can be sustainably mapped in its GIS). Keep in mind that you have no marker in urban places : no mapping too. http://infos-reseaux.com/photos/album/71-dispositifs-reperage If you have suggestions for tags, just share with us. *François Lacombe* francois dot lacombe At telecom-bretagne dot eu http://www.infos-reseaux.com 2014-03-04 12:28 GMT+01:00 Pieren pier...@gmail.com: On Tue, Mar 4, 2014 at 10:16 AM, François Lacombe francois.laco...@telecom-bretagne.eu wrote: Are you going to map the markers only or the whole underground optical cables ?

In France, if you are going to dig a hole, there is a legal process to follow (called DICT) to submit the dig's location to a single point of contact where operators answer with blueprints of their network in the viccinity (got a meeting about that in 30 minutes...). If you hit something mentioned in the blueprints, you are responsible for the damage - otherwise it is the operator's fault for not telling you.

The position of many pieces of infrastructure is indeed not as precisely known as one may expect - for various reasons, many of them having to do with the costs of doing it right vs. letting someone else handle it later (at a greater cost - which may actually make financial and strategic sense). Finding them when a repair is needed is a fun sport - dragging hooks from a riverboat to grab cables (and trash) or beating around the bush to find an enclosure (that is finally found to be in the middle of a Gipsy camp)... Anyway, even if you don a scuba suit and survey a VNF-managed river, users won't be interested because you won't provide sufficient metadata such as which specific cable from which operator you found. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Rarely does the telecommunications link exist on its own, except as directly buried cables that exist in rural locations. I don't agree. Except in rural location may concern some important distance. For years, FT goes through fields and without any support infrastructure to deploy GDL and that's exactly what I'm looking for on sundays. Current example : http://maps.level3.com/default/#.UxX0iBCyPh8 Fibres sometimes follow roads or canals, sometimes not. And never from start to end, cables are always switching from railroads to roads or paths. We can't just establish relations on those supports.

Yes, those rural cables buried directly are long ones and therefore represent a significant share of the network's total length. Opposite case: sewer-borne cables - short, numerous and urban.

Indeed there is room for improvement - we are working on it. As a data producer I can't know what user would be finally interested in. I see things in my environment and looking for the best way to legally, responsibly and technically add it to the map. If you take a major drinking water pipeline such as Aqueduc de l'Avre or the TRAPIL fuel pipeline network, even though they are buried they are associated with a surface trail so clearly visible that one may almost consider setting landuse=pipeline on top of them. They are an important part of how one may describe their location, even though their main feature is underground. In the case of telecommunications infrastructure, I believe that the issue is visibility. I am convinced that mapping features that are not visible directly or indirectly is not going to produce data that Openstreetmap contributors can maintain - and that it should therefore not be present. That leaves many telecommunications features that are excellent Openstreetmap fodder: hosting centers, central offices, street cabinets - we had those discussions before. But visible cables or cable-bearing infrastructure are going to be a very rare exception to the norm of invisibility - better take that into account early to set limited goals and expectations... Unlike your effort on the electrical network which is turning out very nicely ! Well... Back on topic... Let's take inspiration from https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dpipeline and propose: man_made=pipeline type=telecom location=underground operator=* The German man_made=pipeline page already proposes type=telecom https://wiki.openstreetmap.org/wiki/DE:Tag:man_made%3Dpipeline And on the basis of https://wiki.openstreetmap.org/wiki/Tag:pipeline%3Dmarker you would have: pipeline=marker type=telecom operator=* ref=* The key here is to set the hypothesis that you are going to map not cables but cable paths, which may contain more than one cable - in my view, that justifies using the pipeline tagging scheme. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
