You added smoothness=very_bad to some asphalt roads. This is almost never appropriate and it will break routing for trekking bikes.

Please do not add access=no tags to cycleways. This can completely break bicycle routing.

If you wanted to specify that no motor vehicles are allowed, then the correct tag is motor_vehicle=no. However, that tag is generally regarded as redundant for highway=footway, highway=cycleway and highway=path.

The title of this changeset is wrong (carried over from a different changeset), sorry. The title should have been "Sidewalk-related tags and way tags from imagery"

You added tracktype=grade1 to various highway=track ways that you saw while cycling. As documented on the OSM Wiki, grade1 is only to be used for tracks that have a hard covering like asphalt. If the surface is ground or gravel, then the tracktype can only be tracktype=grade2 or below. Please correct this in cases where you remember the surface or it is visible from Mapillary.

You set Bydgoska street at 53.13721, 17.60213 to oneway=yes. Is this really accurate? Both Mapillary and aerial imagery show that traffic on this part of the road flows in both directions.

Previously, the parking ways under Wiadukt Solidarności were tagged as layer=-1, tunnel=yes. This is incorrect, as the Wiadukt Solidarności’s ways are already tagged layer=1, i.e. the parking and its service ways are actually layer=0.

This changeset involved changing the tag surface=concrete:blocks on a road to surface=paving_stones. surface=concrete:blocks is not documented on the OSM wiki. However, the wiki for paving_stones:

surface=paving_stones

shows that this is the appropriate tag for the surface that is visible on Mapillary.

Why did you place a barrier=gate directly on the highway=secondary at coordinates 52.5328166, 17.5630722?

My mistake, fixed in #115769947.

What is your source for pedestrian crossings in Gniezno (e.g. 52.5363003, 17.6222129)? No crossings are visible in Geoport or Mapillary imagery.

According to the OSM Wiki, junction=roundabout is only for ways without right-of-way. This rondo contains traffic signals at various points along it and is therefore a junction=circular.

My apologies. With regard to islands, it looks like we are both wrong. According to the OSM Wiki (footway=crossing), the island portion of crossings should have no footway= tag at all. That is, it should be neither footway=crossing nor footway=sidewalk.

With regard to the two ends of the crossing, however, I still maintain that these should be footway=crossing, not footway=sidewalk. This is how it is normally mapped around the world, including in Poland. Not only are ways typically traced from their centre, but the way these have been mapped in Warsaw does not accurately describe the ways for the sake of routing engines (the major consumer of these tags).

A Warsaw mapper has mapped the island portion of crossings as crossing=sidewalk, but this is widely believed to be incorrect (as was recently discussed on Weekly OSM). footway=sidewalk is for ways that run parallel to associated streets. For crossings, both the zebra paint, and the islands, and the portion of the sidewalk that splits off from the footway=sidewalk (since ways are typically traced from the center), the usual tagging is footway=crossing.

You added tags relating to Dečani Monastery to the way representing the main church within the monastery. These should go on the monastery way which is traced around the entire complex.

Of course, you can add English names under the name:en tag, but there they should reflect standard English capitalization, so name:en=Old Town.

Please do not add English names in Albania. In Gjirokastra you added a place with name=Old town. Name tags should be in the local language.

Sorry, "ways used by driveways to go" should have been "ways used by drivers to go"

You added service=parking_aisle to a large number of service ways in Radom. This is not the correct tag for many of these ways. For example, the service way going through a petrol station is generally not given a service= tag. Also, ways used by driveways to go from the road to their home should be tagged service=driveway instead.

Also, sidewalk-related tags do indeed have to be added everywhere. Not just because editors like Vespucci ask mappers to fill in these details for the sake of data completeness, but also because of real-world usefulness. For roads, it is so that routers will avoid sending pedestrians along the road itself. For sidewalks, it is so that the router can helpfully tell the user clearly "Walk along the sidewalk" instead of merely "Walk along the [unidentified] footway."

My goal in all of this recent tagging of sidewalks (and associated roads) in PL is to improve routing. Developers of routing engines generally go by what is documented on the wiki. In the present case, footway=sidewalk is called the appropriate tagging, while path=sidewalk is referred to as an error. Even if you wanted Polish roads to be tagged a certain way, routing engines are international and their developers cannot be expected to know peculiarities insisted on by a few Polish mappers.

I understand your view that a footway= tag looks incongruous on a highway= that is not a footway. However, you cannot expect OSM tags to be 100% logical. There are all kinds of small inconsistencies in OSM tags.
