See a suggestion by Christoph at https://github.com/gravitystorm/openstreetmap-carto/pull/3844#issuecomment-583848782:
"If anyone wants to develop a followup to this change - i prepared two branches that could be helpful: 1) https://github.com/imagico/osm-carto-alternative-colors/tree/no-barrier-polygons "This implements the complete removal of rendering barrier=* on polygons - as discussed this would remove support for an in general inherently ambiguous mapping practice - which is however unfortunately widely used. It would provide a clean slate in terms of barrier mapping (leaving only the undisputed and consistently used mapping on linear ways) and would allow mappers to decide on an approach without being influenced in a counterproductive direction by this style. It would however also mean removing the rendering of several hundred thousand features currently rendered. 2) https://github.com/imagico/osm-carto-alternative-colors/tree/hedge_polygons_as_landcover "This adds barrier=hedge to the landcover layer and does not render it with the other barrier tags as a secondary tag on polygons any more. Functionally this is somewhat similar to a revert of this change - but it would do so cleanly and consistently with the other tags in the landcover layer. Note this means among other things having features with barrier=hedge default to being polygons, that any other landcover tag has precedence over barrier=hedge and that they are rendered within the normal way_area based sorting of the landcover layer. "I will not submit a PR for either of these changes at this time but i don't want to choke a potential consensus in either direction. If anyone wants to prepare and argue for a change based on either of these approaches that would be welcome and i would be willing to listen to their arguments. "What i would as said strongly oppose however is any change that tries to interpret the area=yes tag in any way on the style level beyond the decision of linestring or polygon on the data import level." Also see https://github.com/gravitystorm/openstreetmap-carto/issues/3611#issuecomment-585573596 about that last question: should `barrier=hedge` closed ways be imported as polygons (necessary for rendering as areas) if they lack `area=yes`? - Joseph Eisenberg _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
