[OSM-talk-be] Land-use mapping with OSM in Belgium

[Gerard Vanderveken]

Hi,

One remark for the wood-tag:
The tag natural=wood 
<https://wiki.openstreetmap.org/wiki/Tag:natural%3Dwood> is sometimes 
used for forests, but since natural=wood would refers to unmanaged, 
natural forests, IMHO it should not be used in Belgium since no more 
forests are completely natural: every patches of forest in Belgium has 
experienced human interventions in the recent history.
In several forests Zoniënwoud, Meerdaalwoud, ... are some nature reserves.
Places where nature can have its course and where only very minimal 
human intervention take place (eg clearance of paths)
I think these reserves (Joseph Zwaenepoel, Kerselaerplein, Everzwijnbad, 
Pruikemakers) could qualify as wood.

I think meadow is a good tag for the grass lands. Conversion between 
farmland and grass land takes somtetimes place but mosttimes as 
incidental crop harvest of grass.
Making a pasture requires also fencing, which is not a temporary measure.

So, when there is a grass land without fence surrounded by farmland, it 
is likely farmland.
Other grass lands are usually fenced and are meadow.
Local knowledge will tell if it is to be one or the other

Regards,
Gerard.
