By that line of reasoning tagging highways anything other than highway=motorway is tagging for the renderer. I understand your concern, but no, it is not our opinion that these car parking areas are unimportant (we wouldn't map them if we thought so). This proposal is not about declaring one type of parking more important than the other. It does standardise a new parking=* and parking:lane=* value for a distinct, commonly mapped, and ubiquitous type of parking area. Because of the way these features are present on the ground, it makes sense for a renderer to consider a different rendering approach than they would for a parking garage of parking lot. And yes, for a general purpose map, that may involve de-emphasizing them. In the Netherlands we've had a case where a misguided mapper imported this type of street-side parking area in one city (the import was not properly discussed and documented and has since been reverted). They used amentity=parking_space on those areas instead of amenity=parking (even though most contained at least two parking spaces), because they didn't like the way amenity=parking rendered on Carto with hundreds of parking areas mapped. That is tagging for the renderer. We want to prevent that. By introducing a relevant sub-tag value renderers and routers may act on, we prevent tagging for the renderer, and encourage the use of a semantically correct tag-value. A collatoral effect is that the existing parking=* values will become less abused (e.g., surface and layby) for street-side parking. Mappers who want to map street-side parking, can do so knowing that any rendering issues can be dealt with by any renderer on the base of the correct sub-tag value. Whether renderers will act on this or not is of course a stylistic choice not part of this proposal, but we do offer some suggestions (under 'Rendering'). Of course, I can fully imagine some types of map or overlay that actively highlight street-side parking! For example some sort of 'parking-mode' on a router's screen when you are nearing your destination. Similarly, some users may prefer street-side parking over parking garages (camper/RV owners perhaps), and instruct their router to filter on those. Our proposal facilitates this: renderers can render street-side parking however they wish, because the tag tells them it is street-side parking. _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
