Hi Eric,

I appreciate that you're trying to identify areas on the map, but I think you need to check these areas a little more carefully before doing so. For instance you tagged the north side of Daqing Avenue in Chinatown as a retail area, but the only retail on the block is a sushi restaurant in the office building on the east side, and a bubble tea joint at the base of the apartment building on the west side. Otherwise you've encompassed an olds folks home and a church within this "retail area". As such it isn't accurate at all.

Hi kbzimmer,

Please note that you broke a turn restriction at 33rd Avenue and 21st Street SW. There are barriers allowing only one-way traffic from westbound 33rd Ave to northbound 21st St; the eastbound 33rd to northbound 21st St is restricted by a no-left-turn sign, and southbound 21st St dead-ends at the (marked...) crosswalk at the intersection with 33rd Ave. Northbound traffic approaching the 33rd Ave/21st St intersection must turn left or right on 33rd Ave: there is no straight-through path for vehicular traffic across 33rd Ave.

Please don't delete this, as I can verify these restrictions do in fact exist.

Thanks

Hi kbzimmer,

Please refrain from deleting any further unmarked crossings in Calgary. Under the "Use of Highways and Rules of the Road Regulation" (see https://www.qp.alberta.ca/documents/Regs/2002_304.pdf , section 1(1)(d)) crosswalks exist at "that part of a roadway at an intersection included within the connection of the lateral line of the sidewalks on opposite sides of the highway measured from the curbs or, in the absence of curbs, from the edges of the roadway". In plainer English, in Alberta a crosswalk exists between the sidewalks at every corner of an intersection, whether it is marked or not.

You've erroneously deleted crossings which do in point of fact exist, where pedestrians have the right of way and vehicular traffic must yield to them and allow them to cross (refer section 41 of the Rules of the Road).

Thanks

Ah, I see. That sign has clearly been defaced. It's "pace car area"...

Mapillary is a service commonly used by other contributors. You could also upload them to a free hosting service such as imgur.com.

I otherwise don't really have any objections to your edits or anything, although please be mindful of what the name key is for. We don't use 'name' to describe things (that's what the description key is for), see osm.wiki/Names#Names_are_not_for_descriptions

Do you mean a "PACE car area"...?

This isn't a neighbourhood "welcome sign" per se, it's a warning that police conduct speed enforcement...

*24 Ave

Thanks for replying. I was a little concerned about the "inaccurate" remark because I wasn't sure if you were under the (mistaken) impression that the +15 network isn't on the second floor ("Level=1"). ;)

With respect to your question, "Is the priority that it is 'correct' in the sense that someone could dig into openstreets and see that - or that the tools being used for navigation are able to understand what is actually being presented?" the answer is the former, not the latter. In short, if the Mapbox API doesn't handle navigation properly because it doesn't know what to do with the level=* tag, that's a problem with Mapbox's API, not OSM. Keep in mind Mapbox isn't the only consumer using OSM data.

One of OSM's most basic rules/good practices is "don't tag for the renderer" (see osm.wiki/Tagging_for_the_renderer). The gist is we don't map things incorrectly for the sake of aesthetics or making it easier for third-party consumers to "use" the data. As a rule if routing or geocoding apps don't work properly we don't jury-rig the map as a workaround.

Per the OSM guidelines for pedestrian navigation (osm.wiki/Guidelines_for_pedestrian_navigation#Ways_inside_buildings) "an indoor way must hold the tag level=* to define the floor where it is located".

There are lots of other errors with the way this is mapped; the fact that most of it is mapped as "foot paths" is in and of itself a potentially large problem, because if a routing API is really using this data properly it should have all sorts of errors about paths crossing buildings. You can also notice many of the path segments are named "Plus 15 Skywalk" or the like, which really shouldn't be; the network relation is named "Plus 15", the paths themselves have no name as such.

Hope this all makes sense.

FYI I've deleted the maxspeed tags you added here. I can confirm from boots-on-the-ground review that there are no signs indicating a 40 km/h speed limit here.

Hello wsmiteh,

I appreciate that someone else is trying to tackle issues with the way the +15 network has been mapped, and "indoor mapping" as a whole is still pretty rough.

That said, with all due respect, how was the level=1 tagging here "inaccurate"? For someone trying to navigate the network does it not help to know the corridors that interconnect to bridges to other buildings are on the level above ground floor...?

Oh, and I deleted node/7251853879 from the map, marking the Calgary Tower. Contrary to the edit summary of the mapper who added it, the Calgary Tower was already on the map...

Hello Test1776,

You tagged this segment of 6th Street with a signed 40 km/h speed limit; where's the sign ? I drove this stretch of road this morning, and can quite literally see it from my office window as I type this message, and I don't see a 40 km/h sign.

I cross-referenced with the City of Calgary's "Neighbourhood Speed Limits" map (https://maps.calgary.ca/NeighbourhoodSpeedLimits/), and this is not among the streets that had its speed limit changed.

Hi there,

I have reverted this change. I know with absolute, 100% certainty that this is in fact a pond. There is however a fenced-in dog park right next to it, which I have also added.

cheers

What you have tagged is simply a private residential garage. As such I have summarily deleted the car wash you added here.

I have rolled back all of the road tagging here, once again. Your reclassifications were incorrect. Please review highway=* and osm.wiki/Calgary#Road_tagging_guidelines for more information, and please desist making more of these changes until you have had a chance to more thoroughly review what these classifications actually mean.

Hello Mahsa,

Per my comment on changeset/99615513 (changeset/99615513) this building was demolished. It. Does. Not. Exist.

I have once again summarily deleted it. Stop adding it back.

Hi Nicole,

The building part you added at 1st St SW & Daqing Avenue no longer exists. It was demolished a few years ago. I have summarily deleted it.

Please be mindful of the age of background satellite imagery.

Thanks

Hello Nabila,

I have deleted the cricket pitch node you added in this change set, and other nodes and ways you had added in this area in the last hour or so across several changesets.

This is a duplicate; the cricket pitch area is already mapped (and tagged properly).

Hello khartley,

I have changed this stretch of "9A Street" back to a sidewalk. It is quite literally just a 1.5ish m wide footpath.

Hello Mahsa,

This building was demolished last year, it no longer exists. I deleted it from the map three days ago (changeset/99408157). I have summarily deleted it from the map again. Please note the age of the aerial imagery you are using for reference; it is sometimes out of date.

Thanks
