If I was reverting your edits, I didn't notice; I was merely adding flowlines where they would fit. I meant no offence and was not trying to start an edit war. My apologies.

My edits followed the current published guidelines. I see that you recently proposed to change those guidelines. I'll wait to see what happens with your proposal before making more edits.

Le Key:waterway de la rivière est continu du début à la fin.

La relation relation/19001065 comprend trois éléments de type « river » et trois éléments de type « flowline ». Mais il est une seule relation.

Je conforme avec ceci: waterway=flowline

The Wikipedia article that brought it to my attention cited the Canada Flight Supplement published by Nav Canada. I don't have a copy of that, but private websites which track airports agree. It's possible the time zone only applies to the airport and not the mine, but that feels unlikely.

That edit was from years ago, so I don't remember what it's based on. When I lived in Edmonton, it was pretty common for people to refer to the entire area from Mill Creek to the North Saskatchewan (relation/9952237) as "Strathcona", ever moreso than the neighbourhood officially named "Strathcona" (relation/7820664).

But I don't know whether the larger Strathcona is official in any way. A quick web search mostly points to the riding with that name, which is roughly the same shape as larger Strathcona. Some also refer to the larger area as "Old Strathcona", although I thought that was just the commercial strip along Whyte Ave. Real estate websites call the larger Strathcona "Scona".

I agree that "Greater Strathcona" is not the right word, but the area is definitely thought of as a cohesive region, so I'd keep the relation under a different name if possible.

I think this change put a hole in relation/10251257. Is there a way to undo that part of the change?

Is there a way to visualize segments of the world that share a timezone if timezones are tagged as properties instead of relations?

I suspect the line used to be part of a relation I created for zones described in the Tsawwassen Nation treaty. But most treaty relations have been removed in BC, so this way isn't needed anymore.

I didn't delete the relation for America/Creston, I just renamed it to "Old America/Creston Timezone". I'm open to changing the name used, but I think it makes sense for Creston to simultaneously be in a relation for the defunct America/Creston and the current America/Phoenix.

The relations for IANA timezones provide that info. For example, Portugal is inside one relation for UTC+0 standard time and another relation for Europe/Lisbon IANA timezone. The UTC-based timezone boundaries are only for standard time and don't take daylight savings into account.

You're going to report that you've been removing publicly verifiable data from the map? Go ahead.

The international border is in dispute. So, I drew each country's border according to the country's own claim, and I tagged the overlapping area as disputed territory.

Which tags are deprecated?

I tried to undelete relation/6498593 using JOSM, but it didn't work, so I made relation/14520100 with the same information.

I haven't found any evidence for America/Nipigon or America/Rainy_River, but the weather station at Thunder Bay Airport did skip DST in 1973, so I think America/Thunder_Bay is real. But it must be smaller than I originally thought because the weather stations near Upsala and Geraldton didn't skip 1973 DST. It's possible that America/Thunder_Bay was limited to the city's 1970 borders. Maybe also the neighbouring first nation territory and national park.

I can't tell which edit this was. What's the problem?

If that's the rule, I'll follow it. Though, personally, I like the names of major rivers rendering like lakes. When you only name the way, it doesn't show up until zoom level 13, which is too close for major rivers like the Dehcho, Yukon, or Saskatchewan

Admin levels 8-10 are used for subdivisions of neighbourhoods. But given Yellowknife's small size, level 9 is probably enough for Old Town.

The name "Mature Area" applies to a large area approximately bordered by 137 Ave in the north, 149 Street in the west, 34 Ave in the south, and the rail line in the east. Most sub-parts of this regions have their own names, like Avenue District and Greater Hardisty. But I didn't know what to do with the sub-parts of the Mature Area that don't have their own name. So, "Western Mature Area" isn't so much a name as it is a description; more like small-w "western Mature Area".
