Re: [Tagging] mapping qanats

OK, I gathered the three ideas here: http://wiki.openstreetmap.org/wiki/Proposed_features/Qanat#Tagging Any thoughts on it? Preferences? I realized it is not easy to make a distinction between canal and aqueduct, but we may assume that the latter is usually for drinking water or irrigation of sma

Re: [Tagging] mapping qanats

On the canal wiki article it says "An artificial open waterway used for transportation, waterpower, or irrigation." I guess we have to add "drinking water" to that list. When you look at the Wikipedia canal article, the

Re: [Tagging] mapping qanats

man_made=pipeline, pipeline=qanat? This is similar to how the aqueduct page proposes to tag modern aqueducts, but qanats seem a distinct type of structure from aqueducts due to the vertical wells. (And I agree with John's point that it is not really like a pipeline, but I'd argue that OSM often u

Re: [Tagging] mapping qanats

I think this is quite a unique structure that can't be described with "canal". Especially if the main reason is rendering. Canals are not used for drinking water, the concept is entirely different. If I had to use anything, I would use aqueduct , but I w

Re: [Tagging] mapping qanats

According to Wikipedia, qanat's are known under different names in other parts of the world (kethara, galerias, foggara, ...). Wouldn't it be possible to use a more generic name? Also, wouldn't we be able to use waterway=canal, tunnel=yes (or whatever tag we use for underground waterways)? Possibl

Re: [Tagging] mapping qanats

I'm not sure whether this should have its own tag; how different is it from either an underground pipeline or an underground canal? __John ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] mapping qanats

Wow, I never heard of qanats. man_made=qanat and qanat=shaft sound ok, although I would rather use waterway=qanat. I see there are only 3 man_made=qanats mapped right now, so there is no problems with changing those. Janko 2013/9/27 Michał Sałaban > Hi, > > I've just created a proposal page

[Tagging] mapping qanats

Hi, I've just created a proposal page about tagging qanats: http://wiki.openstreetmap.org/wiki/Proposed_features/Qanat I hope you will help me to find a good way of mapping these features little known in western world :) Cheers, -- Michał ___ Taggin
