Canadian Passenger Rail in 1955 and 1980

This interactive map, created by Sean Marshall, compares the extent of Canada’s passenger rail network in 1955 with what was left of it in 1980 after decades of service cancellations and line abandonments. By 1980 the various railways’ services had been taken over by VIA Rail; VIA’s network would face the first of a series of cutbacks the following year (there’s a lot less of it extant today), so this map represents the public rail network at its maximum. More about the map from Sean here.

Historical Landslides in Canada

Map: Historical landslides that have resulted in fatalities in Canada (1771-2019)
Excerpt from Andrée Blais-Stevens, “Historical landslides that have resulted in fatalities in Canada (1771-2019),” Geological Survey of Canada, 2020.

The third edition of a map showing landslides that have caused fatalities in Canada since 1771, created over six years by Geological Survey of Canada research scientist Andrée Blais-Stevens, was recently released. The Ottawa Citizen has the story; the map in question can be downloaded in PDF format here (48.7 MB).

A Network Map of Ottawa’s Cycling Network

Hans on the Bike has produced a map of the Ottawa-Gatineau bicycle path network in the style of a Beck-style subway network map. “Is a metro map for cycling useful? I think it has a function in visualizing a network in an easy and pleasing way,” he writes. “In the end it is more a fun project than a bike map avant la lettre.”

Nothing wrong with it as a fun exercise, but can it actually be used? As someone who back in the day biked quite a lot of the Ottawa and Gatineau bike trail network, I can’t use this map. I don’t recognize the path network. Part of it is because many of those paths have names that he doesn’t use; part of it is the conceit of creating “stations”; part of it is that a surface path network that can be entered or exited at any point is not well served by a network diagram. It makes sense to abstract a subway network from the street level, because you’re basically travelling from station to station. You’re not doing that on a bike; you’re in the neighbourhood.

Apple Maps Updates Canada

Apple’s new maps, first announced in 2018, have finally come to Canada: they went live country-wide on 10 December. See coverage from AppleInsider and MacRumors; Justin O’Beirne compares the new maps with the old.

The update also includes Look Around, and not just in a few locations. Elsewhere in the world, Look Around is being rolled out on a city-by-city basis; in Canada it’s far more comprehensive. How comprehensive? I live in a village of 1,600 people not far from Ottawa, and my house is on it. (Based on the state of our gardening, the imagery was taken sometime in 2019, either in late summer or early fall.) Major highways are also included, not just cities. Justin O’Beirne looks at the coverage areas.

Canada is the fourth country to get the new maps: Ireland and the U.K. got them in October.

Approved and Rejected Place Names in Ontario

CBC News explores how places in Ontario receive new names. There are hundreds of thousands of unnamed places in the province, and at the rate new names are being approved by the Ontario Geographic Names Board, it’s likely to stay that way: 85 new names have been approved in the past five years. On the other hand, 54 proposed names were rejected for not failing to meet the rules, which the article digs into:

The Ontario Geographic Names Board is guided by a strict list of naming rules. Submissions can’t have the same name as another nearby feature. Bad words are not allowed, nor are names that could seem like advertisements.

When it comes to people, a name won’t be considered unless that person has been dead for at least five years. Even then, there’s niche criteria. The person needs to have left a legacy either locally, provincially or nationally.

There’s even a rule about not naming something to commemorate a victim of an accident or a tragedy if they didn’t leave some sort of other legacy.

Beaded Maps of Canada and the United States

CBC News reports on a collaborative project to create province-by-province and state-by-state beaded maps of Canada and the United States. “Since March, dozens of Indigenous artists had been taking up a challenge to bead their states and provinces. Their hard work, diversity in beading styles, techniques, and cultural influences can be seen in a final map that was recently unveiled of both countries.” The project was coordinated by CeeJay Johnson of Kooteen Creations.

Monitoring the Arctic Heat Wave

The European Space Agency has a post about monitoring the Arctic heat wave (mainly, it seems, through the Copernicus program). It’s illustrated by a few startling images from this summer: of Siberia’s wildfires, the record-low levels of Arctic sea ice, and (above) a map showing the land surface temperatures on Ellesmere Island, Nunavut on 11 August, when Eureka, Nunavut—80° N—had a record high of 21.9°C (71.4°F).

Canadian Election Atlas Adds 2019 Results

Election-atlas.ca, the collection of historical Canadian election results maps I first told you about in 2018, has added poll-by-poll results for the 2019 Canadian federal election. Also, since we last saw them it seems they’ve extended their historical results further back in time—as far back as 1896 for the federal results.

An Interview with Margaret Pearce, Mapmaker of Indigenous Place Names

Coming Home to Indigenous Place Names in Canada (map)

Coming Home to Indigenous Place Names in Canada, a wall map of indigenous place names in Canada, came out in 2018. A few days ago Design Feminism posted an interview with the mapmaker, Dr. Margaret Pearce, in which she talks about engaging with Indigenous communities, her design decisions, and other behind-the-scenes detail.

Mapping Canadians’ Attitude Towards Climate Change

Researchers have released an interactive map showing Canadians’ opinions about climate change—whether it’s happening, and what we should do about it—and, more significantly, the regional variations in that opinion, down to the riding level. Not surprisingly, the oil- and coal-producing regions are much more likely to be climate skeptics.

The map is based on surveys of more than 9,000 Canadians taken between 2011 and 2018, which raised my eyebrows a bit: public opinion can change a lot over seven or eight years, after all. But the researchers did so to get a more accurate sense of regional opinion: opinion polls are usually based on a small national sample; regional breakdowns of that sample have large margins of error, and getting accurate regional samples would be a lot more expensive.

MTLBlog digs into the digital holdings of the Bibliothèque et Archives nationales du Québec (BAnQ) to present some vintage maps of Montréal.

The BAnQ has more than 20,000 maps in its digital collection, ranging from the 16th century to the present day; said holdings include maps from before the Conquest, maps of cities, towns and villages (many of them fire insurance maps), and historic topo maps.

Mapping the Canadian Election Results: Technical Details

Bothered by the widespread use of Web Mercator by Canadian news outlets to show last week’s election results, Kenneth Field has posted an article that aims to address the problem. Static maps of Canada tend to use a conic projection like the Albers or the Lambert, and that’s the case for print election maps as well. Online interactive maps, on the other hand, use off-the-shelf tools that use Web Mercator, which results in the sparsely populated territories looking even more enormous. But that doesn’t have to be the case, says Ken, who shows us, with a few examples, how use ArcGIS Pro to create interactive maps using a conical projection.

Meanwhile, Mark Gargul writes in response to Ken’s critique of his cartogram of the election results. Mark describes himself as an amateur and readily admits that other cartograms are “clearly more aesthetically pleasing. On the other hand, I was going for something different with my cartogram—specifically, to try to preserve riding-adjacency as much as possible.”

The other thing Mark was going for in his cartogram was to indicate the urban-rural split: metropolitan areas are given a black border: it’s easy to see which ridings are in Montreal or Toronto; seats that are partially urban and partially rural straddle those borders.

So it’s doing several things at once that may not be immediately apparent.

More Canadian Election Maps

I hit “Publish” too soon last night. Kenneth Field and Craig Williams put together a series of maps showing the Canadian election results in a number of different ways: we have a value-by-alpha map, a proportional symbol map, and two kinds of dot density maps: one showing the winners, one showing all votes per constituency. (One dot equals 100 votes; the dots are spread evenly across constituencies, even when people aren’t. You can’t have everything.) And it’s on the Lambert, not the Mercator.

Speaking of the Mercator. Maps Mania’s roundup of Canadian election results maps notes that the Canadian media’s interactive maps (e.g. CBC, Global, Globe and Mail) invariably resorted to Web Mercator, largely because of the mapping platform used. (In-house infographics team? Don’t be ridiculous.) Web Mercator is singularly bad for Canadian election maps, because Nunavut: it’s the largest electoral district by area (1.9 million km2) and the smallest by population (31,906). It’s enough of a distortion on the Lambert: Mercator makes it worse.

As for cartograms, Ken hated the one I posted last night; Keir points to Luke Andrews’s Electoral Cartogram of Canada, which is a bit nicer, and uses only one hexagon per riding instead of seven. Keir also points to this animation that shifts between a geographical map and a cartogram. It’s hard to recognize Canada in cartograms, because it’s difficult for us to grasp just how many people live in southern Ontario.

A Cartogram of Canada’s Election Results

This cartogram shows the seat-by-seat results of the federal election held last Monday in Canada. It was uploaded to Wikipedia by user Mark Gargul to illustrate the 2019 Canadian federal election article, and it’s a welcome departure from the usual election results maps in this country.

(An example of the usual results map is Elections Canada’s official map of the unofficial results, in PDF format.)

Canadian election results maps generally use geographic maps, usually the Lambert conformal conic projection that most maps of Canada use (though sometimes it’s the Mercator!) rather than cartograms. Which means that Canadian maps suffer from the same “empty land doesn’t vote” problem that U.S. maps have, though it’s mitigated by the fact that vast rural and northern seats are often won by different parties: you don’t have the same sea of one colour that you get in the States.

That said, Canada is overwhelmingly urban, and so are its electoral districts. Most election results maps resort to using multiple inset maps to show the urban results. (Elections Canada’s map has 29 of them.) Gargul’s cartogram sidesteps both problems neatly; on the other hand, it’s next to impossible to find your own damn constituency (it’s hidden in the mouseover text). If the disadvantage of empty-land election results maps is that the colours aren’t representative, their advantage is that you can tell what regions voted for whom, at least if you know your geography.
