Re: [Tagging] Irrigation: ditches, canals and drains

I believe all are drains. None have width tagged, as I just researched it for the pictures. Tagging width from imagery is difficult, as even a small amount of weeds/grass can obscure their true size. The resivoir box just happens to be our residential area's garbage transfer point (you can see t

having 2 key with the same meaning is not a good thing. I'm in favor of deprecing service=irrigation in favor of usage=irrigation, more consistent with other usage=* values used on other waterways. Le 03.06.19 à 22:19, François Lacombe a écrit : > Hi all > > Regarding the particular situation of

Hi all Regarding the particular situation of service vs usage keys, JOSM team wonders if service may be moved to usage https://josm.openstreetmap.de/ticket/17770 Don't blame them on "deprecate" word, which should be understood as "discouraged". Question is "Should we keep service in use for desti

The usage of the word "aqueduct" in American English is broader than the meaning of the word in British English. Cambridge dictionaries defines the noun as "a structure for carrying water across land, especially one like a high bridge with many arches that carries pipes or a canal across a valley"

Thank you for the information about Japan. How are the small drainage/irrigation channels tagged currently in Japan? Are most tagged as waterway=drain, waterway=canal or waterway=ditch? We have lots of these in Indonesia, in the rice-growing areas with irrigated fields, but most are more like de

I had a chance to look at these 4 examples of small artificial waterways used for irrigation or drinking water and lined with stone or concrete, suggested to be tagged as =aqueduct 1) This is a shallow, straight waterway about 1 meter wide, which is the bottom of a wider depression, in a semi-arid

Which of the ways of tagging "irrigation" should be used? "irrigation=yes" works ok, but it hasn't been very popular the last few years "service=irrigation" is still most common, but the key is a little odd "usage=irrigation" makes sense and is increasing in usage See chart of usage over time: ht

[Tagging] Irrigation: ditches, canals and drains

It looks like our long discussion a while back didn't lead to substantial changed to the wiki pages for waterway=drain, waterway=ditch and waterway=canal. I was checking on how many waterway=ditch were tagged as being used for irrigation, and decided to slightly updated the pages. I've marked all
