<div dir="ltr">It's going off in all directions again...<div><br></div><div>I asked: </div><div>What about the idea of supporting the proposed landcover values to the natural key?</div><div><br></div><div>That is: for the natural key, support the values grass and trees.</div><div>This would help to map areas of trees and grass comprised within a larger landuse e.g. military, residential, industrial. </div><div>It would avoid the practice of mapping natural=wood or natural=grassland for those areas. </div><div><br></div><div>It accepts the current practice that the natural key describes land forms as well as land cover and features growing on the land such as a single tree or a line of trees. </div><div><br></div><div>It would require no retagging of any kind. <br></div><div><br></div><div>It just solves the issue that you can't map land cover and land use for the same feature if landuse is used for land cover. </div><div><br></div><div><br></div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature">Vr gr Peter Elderson</div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Op do 5 mei 2022 om 22:51 schreef Peter Elderson <<a href="mailto:pelderson@gmail.com">pelderson@gmail.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>I got notice that the latest landcover proposal turned to "inactive". <a href="https://wiki.openstreetmap.org/w/index.php?title=Proposed_features/landcover&diff=next&oldid=2124394" rel="noreferrer" target="_blank">https://wiki.openstreetmap.org/w/index.php?title=Proposed_features/landcover&diff=next&oldid=2124394</a></div><div><br></div><div>Which is correct.

And, the same landcover occurs on or within different landuse areas. </div><div><br></div><div>2. that the proposed values are much more compatible with the natural key, and in fact already exist there. This according to the now predominant view that natural= does not say it's nature as opposed to human, but rather expresses that the element grows or flows by itself, possibly (often) influenced by humans, but it has a 'life' of its own.</div><div><br></div><div>3. the proposers make exceptions for water, sand and scrub, because they do not think people will ever change those to landcover. I agree. </div><div><br></div><div>So my current thinking is: </div><div>If such landcovers can exist and be applied massively without problems within the natural key, then the other proposed landcovers can also exist in the natural key.</div><div><br></div><div>And in fact they already do. </div><div><br></div><div>Proposed landcover=sand already exists as natural=sand</div><div>Proposed landcover=water already exists as natural=water</div><div>Proposed/used landcover=trees is almost equivalent with natural=wood</div><div>Proposed/used landcover=grass is almost equivalent with natural=grassland<br></div><div>Proposed/used landcover=scrub is equivalent with natural=scrub</div><div><br></div><div>I wouldn't mind support for natural=trees (so natural=wood can be reserved for the landscape type) and natural=grass (so natural=grassland could be reserved for the landscape type) but I doubt if that would make any practical difference. </div><div><br></div><div>This would enable taggers to stop using landuse=forest for any small area with some trees, and landuse=grass for any small patch of grass.
