Hi Joost, Yes, I'm interested in your land-use analysis that you did. Did you share or present the code somewhere? Maybe we can plan smthg for the next FOSS4G.be event? A discussion about a tag "forest_management_style=*"? Wow, it can be dangerous, especially if we have hunting supporters vs

I have no problem to use landuse=forest, and not natural=wood for any patch that is "big enough". I would not use it in gardens, especially not private garden. I would try to avoid using it when natural=tree_row is the better choice. I think landuse=residential is wrong under amenity=school,

That's definitely an interesting answer. It seems that dividing the large landuse=residential is something that we should do (as it seems logical, even if can be tedious sometimes). I did some digging into the wiki for trees tagging and came to these conclusions. When we think about the key

I understand your point, and that's why we should say if something must be done or not : describing the best practices. For landuse inside an existing residential area, it is always possible to just change the residential zone into a multipolygon relation and make the new landuse (like the park)

the landuse under roads should be highway, this has been discussed in the past. Never got popular. Alternative is area:highway, which is more popular I believe. But you won't split the current residential areas on each street, would you ? I think overlaying landuse=residential with leisure=park

Personally, i put Nature reserve on a special relation, as it is described on the wiki, like this one : http://www.openstreetmap.org/relation/7130732#map=17/50.68519/4.70461 And the forest or other landuses are just part of this multipolygon. In this example, i also have a multipolygon for the
