<div dir="ltr">My first few years of osm mapping were mainly spent mapping barriers. I was doing this from walks where I was photo mapping along with satellite imagery.
<div><br>
</div>
<div>Most of this was straight forward. Complications were hedges that were no longer maintained as an effective barrier. I.e. now just interspaced trees. I thought about using natural=tree_row but eventually kept with hedge as this is what they originally
were. Another possible complication is trees along streams that have grown up naturally and now form a barrier. Historic maps can help to determine if this the case or it was a field boundary/hedge. If there is no historic boundary I would use natural=tree_row.
</div>
<div><br>
</div>
<div>Some hedges look like tree rows but are actually hedges that haven’t been maintained/cut for the last 50 years.</div>
<div><br>
</div>
<div>Where I have mapped there are many stone walls. In some areas these are totally neglected and a whole range of trees and scrubs has grown up along them. The wall may not been seen on satellite imagery. I maps the wall and put a separate way for the
tree row next to it but I guess you could also assign the tag to the barrier. </div>
<div><br>
</div>
<div>More recently I have been going over some of this original mapping. Given it is a very large area and may take me years I have been using the tasking manager to manage this. In many areas, large trees interspaced in the hedges are very much part of
the landscape character. Indeed we live in an area designated as a “special landscape” for planning applications and this area was partly determined by the number of large interspaced trees along hedges. If you want to map this level of detail it is probably
easier (if using JOSM) to put all the nodes for trees in first, search for empty nodes and add the tree tag and then add the hedge barrier/way.</div>
<div><br>
</div>
<div>Another thing I often do now is map large (I.e no walker’s) gates as ways. I wish I had done more of this the first time round as it is much harder to put these in afterwards. Now, if I didn’t have the time to put in the gate as a way I would more likely
leave a gap which makes it much easier for someone to add the gate later. </div>

<span>IMHO the point of mapping the type of barrier is 1) character - give an impression of what an area is like in map form. Here it does not really matter whether each specific stretch is squeakily correct. 2) Navigation. So the most obvious; which is typically
the hedge.</span><br>
<span></span><br>
<span>I'll also be cheeky and promote one more thing: Mapping from aerial imagery is normally needed to systematically map an area, at least to start. It is not always possible to distinguish so I have used the non-standard barrier=yes to to be safe. I think
it would a useful addition.</span><br>

leaning towards mapping whichever is the most obvious barrier.</span><br>
