Apple Maps’s detailed three-dimensional city maps, which launched in a limited number of cities with the release of iOS 15, have now come to three Canadian cities: Montreal, Toronto and Vancouver. Among other things, the maps add enhanced navigation and transit directions; Montreal also gets cycling directions. [The Verge]

Traffic Data Inadvertently Revealed the Start of the Russian Invasion
AppleInsider looks at how online maps (Apple Maps, Google Maps), especially their traffic layer, inadvertently revealed Russian troop movements at the start of the Russian invasion of Ukraine.
The sheer volume of mapping data now available at our fingertips means it was possible for civilians half a world away to see when Russian forces began moving. Specifically, that data pinpointed a traffic jam starting on the Russian side of the border, actively moving into Ukraine in the first few minutes of the Russian and Ukraine conflict.
Just as with any cartography, this information required interpreting. Google Maps did not specifically say that it was troop movements, nor was its satellite imagery up to the minute. During the process of researching this story, we’ve confirmed that Apple Maps presented similar inbound troop movement information—but it wasn’t setting out to do that either.
What these services did, though, was register all of the smartphone users whose driving was slowed or halted by unusual traffic conditions. Wherever the majority of the data came from, it was possible to determine what was happening when coupled with known details of Russian troop locations.
Engst’s Experience with Mapping Services
Adam Engst of TidBITS: “I’ve been working with mapping services a lot of late and wanted to share some of my experiences in the hope that they’ll help you boost your mapping game beyond simple navigation.” Mostly focuses on fitness-related mapping, but also on how to correct errors on online maps.
TomTom Says Its Algorithms Avoid Potentially Dangerous Routes
It probably has nothing to do with Google redirecting traffic up poorly maintained mountain roads during a blizzard in California last month (previously), but TomTom has posted a piece explaining how its algorithms avoid sending drivers down potentially dangerous routes in Finland even though, on paper, they’re shorter.
TomTom’s routing and location technology recognizes that the shorter route to Koli National Park is on winding unpaved roads, made up of sand and gravel, and it takes that into consideration when computing a route for a driver. It places significant importance on this information. […] Even though the unpaved route is shorter, it’s still not considered “better” than the longer paved route when all things are considered. If map data didn’t include this contextual data about the specific road, the unpaved road would most likely be the default route suggestion.
Google Rerouted Traffic Up Poorly Maintained Mountain Roads During a Blizzard
Last week, when a snowstorm closed Interstate 80 east of Sacramento, Google Maps started redirecting traffic up poorly maintained mountain roads, which is about as good an idea during a blizzard as it sounds.
.@googlemaps This is an abject failure. You are sending people up a poorly maintained forest road to their death in a severe blizzard. Hire people who can address winter storms in your code (or maybe get some of your engineers who are stuck in Tahoe right now on it). pic.twitter.com/IzagAXzBtA

Other dispatches from Twitter allege that the service—particularly its mobile app—directed people to closed-off highways, mountain passes and lakeside roads to get around. This is in direct contrast to Caltrans’ messaging to avoid workarounds. Caltrans District 3 spokesperson Steve Nelson told SFGATE on Monday that they were seeing drivers trying to skirt highway closures with side streets. “They’ll take side roads and try and sneak past the closures, and that never ends well,” he said.
Google engineer Sören Meyer-Eppler responded on Twitter to spell out some of the technical and logistical problems involved in rerouting traffic during bad weather: the difficulty in finding timely data (and in such cases data need to be really timely) and the risk of false positives.

Apple Maps Update: Detailed 3D City Maps, AR Directions
Apple Maps’s detailed 3D city maps are now available for six cities: London, Los Angeles, New York and San Francisco at iOS 15’s launch, San Diego and Washington D.C. last month, and now Philadelphia [AppleInsider, MacRumors]. Those cities also have augmented reality walking directions: AppleInsider has a tutorial.
Apple Maps Asia-Pacific Update
Apple’s new maps have come to Australia [9to5Mac, MacRumors].
Meanwhile, the South China Morning Post reports that “iPhone and Apple Watch users in China can no longer see their geographic coordinates and elevation on the Compass app, according to Chinese media reports and user comments. However, information including bearings and general location are still available.”
And according to a report in The Information (paywall) that was summarized by John Gruber, back in 2014 or 2015 the Chinese State Bureau of Surveying and Mapping required Apple Maps to make the disputed Diaoyu (Senkaku) Islands appear large even when zoomed out, and made the Apple Watch’s Chinese release contingent on that request—to which Apple acquiesced.
Google Maps Announcements
Google Maps updates this week: wildfires are getting their own dedicated layer in Google Maps; their tree canopy coverage tool is being expanded to 100 cities; and a new Address Maker app will make it possible to bulk-add Plus Codes to locations without addresses.
MapQuest to the Rescue?
Adam Engst of TidBITS had a specific routing problem that only one map app could solve. The answer, as they say, will surprise you: “When faced with needing to visit 43 different addresses, what was the most efficient route? It’s easy enough to enter an address into Apple’s Maps or Google Maps, and even add an extra stop or two. But 43 stops in an optimal route? […] A little research revealed that MapQuest—remember MapQuest from the days when we all printed directions?—offers precisely what I needed.”
A Look at Apple Maps in iOS 15
MacRumors takes a look at the changes to Apple Maps in iOS 15. “Apple has made so many improvements to the Maps app in iOS 15 that it’s almost an entirely different experience. There are better driving directions, improved transit directions, and more immersive AR-based walking directions.” That’s maybe a bit over the top, in the fashion of the Apple-focused tech press, but at any rate there are a bunch of screenshots.

Google Maps: Android My Maps Discontinued, Transit Crowdedness Feature Expanded
The Google My Maps Android app is being closed down in October. You may remember that My Maps is a feature allowing users to create custom maps on the Google Maps platform relatively easily. To be honest I wasn’t aware that it had its own Android app; once that’s closed it will be available via the web. Andro4all worries (Spanish) that this is a sign that My Maps could be discontinued, which on the one hand seems a bit premature, but on the other, well, Google does have a track record. [Alejandro Polanca]
Meanwhile, Google Maps has expanded its feature that predicts crowdedness on transit lines—useful when it’s still very much not a great idea to be in a packed subway car—to 10,000 agencies in 100 countries. [Macworld]
Apple Maps Updates Announced at WWDC
Upgrades to Apple Maps were announced on Monday at Apple’s Worldwide Developers Conference: see coverage from AppleInsider, Engadget and TechCrunch, as well as the video of the keynote itself (the Maps section starts at 29:47).
The changes will be coming to iOS 15, iPadOS 15, and macOS Monterey this fall. They include highly detailed city maps (for only a few cities at launch); a three-dimensional map for navigation that indicates, among other things, complex intersections; improved transit features such as bus route integration and next stop notifications; precise walking directions based on a scan of nearby buildings; and an interactive globe when zoomed out. (Note that not all of these features will be available on Intel Macs, which lack the Neural Engine in Apple’s own chips, nor on older iPhones or iPads with an A11 or earlier chip.)
The Weather app will also be getting temperature, precipitation and air quality maps (see TechCrunch coverage). And Italy and Australia were announced as the next countries to get Apple’s upgraded map layer.
Update 11 Jun: MacRumors has a roundup.
Update 15 Jun: Justin O’Beirne has been adding screenshots of Apple’s redesigned maps—its new new maps—to this page.
