[talk-au] Mapping tree cover

[Warin]

Hi,

I removed the tree tagging from the National Park boundary.

This had caused people to exclude water areas from the Park - which is 
not true.

IIRC Graham objected to the now blank landcover.

I did go back and created landcovers for the general area. This was 
quite some time ago!

If the tree cover has grown then map it! I have no objection. You may 
find different imagery is more current then other imagery - be selective.

I think someone else did ask if they could change some of it... while I 
do take some notice of changes to some of "my" data ... it really is 
OSM's data and not "mine" so I am not that possessive of it.


So bottom line for changes to the map - do it. As long as it is not 
destructive all is good.


Regarding landcover=trees and similarly landcover=grass... my and others 
alternative to the natural=wood/landuse=forest and landuse=grass debacles.
