<div dir="ltr">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). <div><br></div><div>I did some digging into the wiki for trees tagging and came to these conclusions. When we think about the key definition of <span id="gmail-goog_1194408904"></span><a href="http://wiki.openstreetmap.org/wiki/Key:landuse">landuse</a>, <a href="http://wiki.openstreetmap.org/wiki/Landcover">landcover</a> (including its <a href="http://wiki.openstreetmap.org/wiki/Proposed_features/landcover">proposed page</a>) and <a href="http://wiki.openstreetmap.org/wiki/Key:natural">natural</a>, i came to the conclusion that the only landuse tag for tree is "landuse=forest". Because the key "natural" is described as a landcover representation. It seems that natural=wood is one of the only special case where a natural tag does represent landuse in common usage (and it seems wrong relatively to the definition). </div><div><br></div><div>If we follow strict definition, the only landuse tag for trees/forest is "landuse=forest". The others are for landcover (like the proposed landcover=trees). Should we then be conservative and use only landuse=forest in Belgium (especially because the definition for natural=wood is very rare for us) ? And use landcover tag on top of others landuses if needed (like for tree in parks). </div><div><br></div><div>Following all these definition note that landuse include the keys landuse=*, amenity=*, leisure=* and tourism=* all as landuse representation, it implies that we should also remove the landuse=residential (or any other) where we have something like amenity=school (because it is already a landuse that probably better fit than the landuse=residential). What do you think about that ? </div></div><div class="gmail_extra"><br><div class="gmail_quote">2017-04-28 22:16 GMT+02:00 Marc Gemis <span dir="ltr"><<a href="mailto:marc.gemis@gmail.com" target="_blank">marc.gemis@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Here is one answer I got, Martin was so kind to put it into a diary<br>
