[Talk-GB] Large swaths of "heath" in Wales?

[Marco Boeringa]

Hi all,

I noticed that in Wales, large parts of the Snowdonia National Park have 
been covered with natural=heath, much of which seems blatantly 
incorrect. Although I am from the Netherlands, having studied for half a 
year in Bangor in 1993, I know the area around Snowdon mountain and 
Llanberis quite well, as I made several hikes there. As you all know, 
there is much more variation in the natural landscape there, for which a 
single swath of heath seems wholly inappropriate as a representation of 
the landscape. Even along the outer borders, the features often seem 
totally disconnected with reality looking at Bing, there is often no 
real visible difference in the landscape, or clearly other types of 
landscapes and natural features, all of this also strongly suggesting a 
possible import of some small scale, coarse landscape map.

Lastly, the lack of proper multipolygon creation, means that other types 
of renderers and styles than Carto, and GIS's like QGIS and ArcGIS, that 
do not stack features based on size but need multipolygons to deal with 
polygon-within-polygon problems, have many older detailed features 
covered up by these new ones, as the original data may be hidden beneath 
the newly added ones.

I noticed the particular user who initially created these features is 
already under scrutiny of the British community, based on the profile 
page and history of the objects, but what are the plans of the community 
with these features? Looking at the current data, I would really suggest 
a revert of the changesets, but considering some of these features seem 
to have been left for a couple of months already, are there any other 
ideas in the UK community?

P.S. I did notice the other discussion started by user "sk53.osm" about 
these problems caused by this user and natural=heath:

http://gis.19327.n8.nabble.com/natural-heath-td5888994.html

but that discussion seems to have veered of course into a general 
discussion of quality control tools, and didn't really answer the 
question of what the community intends to do with all this disputable 
data, despite a small suggestion by Andy to possibly keep some of the 
data as maybe already corrected by other users.

Marco
