Hi folks This is probably a rather minor, even pedantic point but I do like to understand things! I put a gate in a fence to a recreation ground but OSM is just showing a gap in the fence. https://www.openstreetmap.org/#map=19/52.09148/-0.24885 - to the leftside parking area. The gate is for grounds maintenance vehicles and so closed for public access. I marked it no access. In comparison, the gate does show as a thicker line on the following map which I think is a better representation https://map.atownsend.org.uk/maps/map/map.html#zoom=14&lat=52.08781&lon=-0.24703 Could someone please explain? Should I make any changes? Upon re-reading my query, I apologise if it comes over as critical of OSM. I suppose I ought not to compare with other derived maps. Having said that, I still don't understand why the gate doesn't show at all when the related fence does. asked 03 Jun '21, 17:49  Terry edited 03 Jun '21, 18:56 |
One Answer:
The issue seems to be the mapping of the gate as a way rather than a node (compare the rendering of the gate on the right of the parking). Mapping a gate as a way as you have done, while much less common than mapping as a node, is valid according to the wiki page for barrier=gate. And as the second map shows, at least some renderers interpret it in a meaningful way. However it looks like the maintainers of the standard layer have decided not to render gates mapped as ways, see discussion at https://github.com/gravitystorm/openstreetmap-carto/issues/3929 and also at https://wiki.openstreetmap.org/wiki/Talk:Tag:barrier%3Dgate#Mapping_on_a_way_instead_of_a_node.3F answered 03 Jun '21, 18:58  alan_gr edited 03 Jun '21, 19:23 |
Thanks for replying. I've taken a look at the discussion links; some of the points went over my head - lol! I take your main point about different map renderings. I suppose I don't want to spend time adding things to OSM if they're not going to be seen. However, as you point out it's still useful for derived maps targetting particular users.
