landuse=grass?!!! No. City planed 'open area' might be better?
The surface is a land cover, not a land use issue. An 'open space' could 
be concrete and still used for recreation, eating lunch or enjoying the 
sun.
Huumm example? Some 'town squares' are paved.
So landuse=open_area ???

landcover=vegetation?

This avoids the 'mixed' so can be applied to satellite imagery where the 
vegetation is unresolved ... and can be used by locals to identify areas 
where a local survey could be performed to improve the mapping.
