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.

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?

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.

Re: [talk-ph] landuse = farm

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

[talk-ph] landuse = farm

2017-03-27 Thread David Groom 

I've just seen this discussion on the main OSM talk list

https://lists.openstreetmap.org/pipermail/talk/2017-March/077741.html

The standard OSM rendering will soon drop the rendering of "landuse = 
farm".


There are :

66 Relations
7,390 ways
71 Nodes (interestingly the wiki did not recommend this tag on a node)

tagged "landuse = farm" in the Philippines.

Shall I start looking at the  relations and ways and change where 
appropriate from "landuse = farm" to "landuse = farmland"?


What do you think?

David

[talk-ph] landuse=farm is not landuse=meadow and vise versa

2011-10-20 Thread maning sambale 
I've seen this somewhat loosely interchanged in some areas.  Ian Lopez
pointed me to this issue as well [0].

landuse=farm - areas used for tillage and pasture (animals,
vegetables, flowers, fruit growing). [1]
landuse=meadow - areas of land primarily vegetated by grass plus other
non-woody plants. [2]

From the above definitions, they area clearly different.  You can also
add crop=rice for ricefields.  I. e. landuse=farm, crop=rice.
