Some things aren't always visible or clear from aerial imagery and need to be surveyed in person. I'm sure the intent of this phrase is not to encourage people to delete anything they can't see on aerial imagery, but it could be interpreted that way. Yes, there have been several disputes between editors because of this exact scenario. Also, I often need to keep a disused:shop=* around because the newest street-level imagery in an area is from before the shop closed. Sometimes mappers can be complacent about street-level imagery being fresher or more ground-truthy than aerial imagery, but this is not necessarily the case. -- m...@nguyen.cincinnati.oh.us ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] razed railways and other things that don't exist today
I would mention - it is OK to temporarily map ones not visible on aerial images but likely to be mistakenly remapped - "can safely be removed" - would change that it not only can be removed, but also should be removed 5 gru 2022, 11:26 od 61sundow...@gmail.com: > I have placed what I believe is a summary of this discussion on the OSM wiki > for lifecycle > > It reads > > "The following tags function is to reduce the possibility of a mapper > remapping the feature from existing satellite imagery that shows the old > state of the feature.

Re: [OSM-talk] razed railways and other things that don't exist today
I have placed what I believe is a summary of this discussion on the OSM wiki for lifecycle It reads "The following tags function is to reduce the possibility of a mapper remapping the feature from existing satellite imagery that shows the old state of the feature. Once the OSM available satellite imagery does not show the feature the feature can safely be removed from OSM. Renders cannot rely on OSM preserving physically vanished history." There after follow the tags 'demolished', 'removed', 'destroyed' and 'razed'. https://wiki.openstreetmap.org/wiki/Lifecycle_prefix#Stages_of_decay If there are any further thoughts or even corrections to my text above then please post them here. My own thoughts? I have not placed any warning about mechanical edits to seek these out as enough warning is evident in the requirement for it to be not shown in the OSM satellite imagery, which would discourage me so I think it will work with others. ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
