Re: [OSM-talk] Culvert and average contributor
The term culvert is also standard usage in American English. Tunnel is generally used to mean an underground passageway large enough for a person to walk through, if not larger. Also, the default assumption is that a tunnel is not intended for drainage, unless there is a longer phrase such as sewer tunnel. A culvert refers to a tube or pipe under a roadway or other raised area, meant to carry surface-water runoff. Some are large enough to walk through, but most aren't. Usually they extend only for a short distance, such as the width of a roadway. Covered does not indicate the size of a passageway, nor does it indicate the intended purpose of the passageway. ---Original Email--- Subject :Re: [OSM-talk] Culvert and average contributor From :mailto:rich...@systemed.net Date :Thu Aug 26 13:10:13 America/Chicago 2010 Pieren wrote: Question 1 : is culvert commonly used by native english speakers ?

Well, the culvert is used where the waterway passes under the roadway. Also, many culverts are located where there is running water only during, or shortly after, a rainstorm, so the ditch or low spot they are intended to drain may well not be marked on the map.

The way I understand it, a culvert is just a tiny pseudo-bridge, physically equivalent to a tunnel under an embankment. Culverts don't show up in the US National Bridge Inventory, which is a database of bridges on public roads. They normally carry water under roads, but may also carry a private farm access road under a highway that splits a farmer's land.

Question 1 : is culvert commonly used by native english speakers ? Is that a term mainly used by civil engineers ? I understand it to be a passage under a road that isn't big enough for a vehicle - maybe a 0.5m pipe for water, or maybe just big enough for some animals, but a human going through a culvert would be abnormal. Question 2 : if not, is it normal that OSM average contributor has to use these technical words just to make the civil engineers happy ? Don't we take the risk to exclude more and more average contributors by adopting such technical vocabular ?

In my opinion, one of the broken things about OSM is the insistence on making up names and not adopting existing professional terminology. Coming up with names is often about a taxonomy and that requires a fair bit of thought. When a relevant professional community has done this, we should just use their definitions. That doesn't mean we can't give readable explanations. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
