Subject: Re: [talk-ph] landuse = farm
Of the 3 options, I also favor option 3. For the record, I've been
saying that landuse=farmland (or landuse=farm before) should be tagged
on the entire farm area and not on individual fields (or rice paddies
if crop=rice). See this post of mine from 2009:
https://lists.openstreetmap.org/pipermail/talk-ph/2009-November/001545.html
There's also a relevant discussion in 2014 regarding the mapping of
individual farm fields/paddies (thread archive is split into two
months):
https://lists.openstreetmap.org/pipermail/talk-ph/2014-August/005229.html
https://lists.openstreetmap.org/pipermail/talk-ph/2014-October/005318.html
For the specific case of rice paddies, there are actually two ways you
can go about mapping things (once you've marked up the whole area as a
single landuse=farmland):
1. Mark the borders between paddies as ways as these are raised lines
of land that serve as walls to hold the water and secondarily serve as
footpaths (but shouldn't be tagged as highway=*) to access individual
paddies. There was the suggestion to use man_made=bund or
man_made=embankment or something similar but no decision was made.
2. Mark the paddies as individual polygons.

During early April I looked at nodes/ways/relations tagged as
landuse=farm as reclassified many of them as appropriate.
Howver , in some places I noted that individual fields had been tagged
using landuse = farm, for example:
https://www.openstreetmap.org/#map=19/11.225924767247454/124.54216374231005
<https://www.openstreetmap.org/#map=19/11.225924767247454/124.54216374231005>
https://www.openstreetmap.org/#map=18/16.933969/121.13637
<https://www.openstreetmap.org/#map=18/16.933969/121.13637>
https://www.openstreetmap.org/#map=17/14.883274660783613/120.25851326487962
<https://www.openstreetmap.org/#map=17/14.883274660783613/120.25851326487962>
At present I have done nothing with these ways
The standard use in OSM for landuse=farmland is for it to be used on
larger areas, rather than individual fields
There appears to be no approved tag in OSM for fields, (though taginfo
<https://taginfo.openstreetmap.org/keys/field#values> shows field=yes
used on 388 occasions worldwide)
There seem to be a number of possibilities regarding these ways:
1) retag them as landuse=farmland
2) delete them and draw a single way round the larger outline of all
the adjacent fields and tag this as landuse=farmland
3) retag them as field=yes, and also draw a single way round the
larger outline of all the adjacent fields and tag this as
landuse=farmland.
Of these I think I favour approach 3 as it keeps the field data in OSM
(someone might have a use for this)
What are your thoughts?
Regards
David

I don't think it will take too long for one person to do this, but I
may be mistaken.
It will also be an opportunity to look at some of the areas tagged as
"landuse = farm", and merge them into adjacent areas where
appropriate.

Shall I start looking at the relations and ways and change where
appropriate from "landuse = farm" to "landuse = farmland"?
What do you think?
Go for it! Would it also make sense to turn this into a Maproulette
task?
