A Map in Every Pocket

It’s been more than 18 years since Steve Jobs demonstrated Google Maps on the then-prototype iPhone, and it’s hard to wrap one’s head around how transformational the fact that every mobile phone comes with a detailed, always up-to-date map of the world. James Killick makes the point in the final installment of his “12 Map Happenings that Rocked Our World”:

Well today there are estimated to be 7.2 billion smartphones in use around the planet. They are used by 4.7 billion people.2 That’s about 58% of the world’s population. 

And every one of those devices has access to a maps app. And every maps app has a map of the planet.

So, if you boil it all down: at least one out of every two people on the planet now has a detailed map of the whole world in their pocket.

Process that thought. Before smartphones with data plans, car navigation meant GPS receivers with onboard maps that needed to be manually updated, often for a fee, or they’d slowly go out of date. And before that? Well, discussion of that (example 1, example 2) is a good way to make people feel old on the Internet. It meant a needing to own collection of paper maps. It meant knowing how to navigate from a map, which ain’t nothing—and was never universal. It meant asking for directions if you didn’t, or if you didn’t have the map you needed.

“A GPS in every pocket is one of the few truly great things about the smartphone age,” wrote Jeff Veillette on Bluesky, and I’m hard pressed to disagree. It will be harder for half the world’s population to get themselves lost: how is that anything but an unalloyed good?

Designing Thematic World Maps for Smartphones

Jonas Oesch

World maps tend to be wide (horizontal, landscape), whereas mobile phone screens tend to be tall (vertical, portrait). This makes world maps small and hard to see on phones: a problem when you’re trying to present data via a thematic world map (e.g. a choropleth map) on a web page, especially if you’re trying to show data on smaller countries. The Neue Zürcher Zeitung recently did a user study to test the efficacy of two map designs—one that splits continents up and portrays them in different scales to make them more legible on vertical screens, the other a hemispheric bubble map. The results were published in The Cartographic Journal; lead author Jonas Oesch provides a summary in this blog post. [Ralph Straumann]

AllTrails and AI-Generated Hiking Trails

Last month the hiking app AllTrails announced AI-generated (“leveraged”) custom routes as part of a new premium membership plan, and some people are worried about it. According to the National Observer, AllTrails and other hiking apps have gotten hikers into trouble because they rely on crowdsourced trail information, which isn’t necessarily official or safe. Given generative AI’s track record for producing spectacularly erroneous results, there would appear to be some cause for concern. Except that “AI” has become a marketing buzzword that covers a lot of computer stuff, from less problematic machine learning (which is what I’d expect in this case) along with more problematic generative AI/large-language models, and AllTrails isn’t indicating which flavour they’re referring to (because: buzzword). And as the National Observer points out, “These problems already existed before the AI was added.” To be sure, generative AI is a blight on human civilization, but let’s be clear about our targets in this case.

Some Minor Updates to Apple and Google Maps

In what seems like a relatively minor update, Apple Maps will learn your preferred routes and remember visited places as of iOS 26, coming this fall. Meanwhile, Google Maps has announced some sustainable travel updates: recommending alternatives to driving, cycling route details, fuel-efficient routing, and marking low-emissions zones in Europe.

Online Maps Updates, Late March 2025 Edition

An updated disclosure on Apple’s website spotted by 9to5Mac says that imagery collected in support of the Look Around feature of Apple Maps (Apple’s Street View equivalent) will also be used to train Apple’s generative AI. Meanwhile, a recent Apple Maps glitch displayed baggage claims at ridiculously high zooms, and a Google Maps glitch deleted Timeline data for some users.

Apple Maps Surveyor

Last week Apple launched Maps Surveyor, a mapping app with a specific purpose, MacRumors reports. “The app is not public facing and appears to be for use with companies that Apple partners with to assign mapping tasks. […] Strings in Apple’s Surveyor app found by MacRumors suggest that once assigned a mapping task by the Premise app, Premise users will be instructed to attach an iPhone to a mount, rotate the iPhone‌ to landscape orientation, and capture images along a route while driving using the Surveyor app.” In other words, it’s the user end of a crowdsourcing pipeline that funnels local data to Apple Maps via a third party “task marketplace.” Not something most of us would ever use.

Apple Exploring Advertising in Maps

There’s talk of ads coming to Apple Maps—at least, Apple is said to be exploring the possibility—which, online consternation notwithstanding, is something Google has had forever—when you get right down to it, Google Maps was a way to provide location based search results, and search results were always monetized with ads. Apple started out using its services as loss leaders for its pricey hardware products; now those services are expected to make money themselves.

Google Maps: Rounded Corners and Live Updates

When not getting into trouble over which name of a certain international body of water to show to which users, Google continues to turn out smaller updates around the corners of their map services. No seriously, the corners: they’re more rounded in the Google Maps app now. Also, Google Maps supports Android’s Live Updates, viz., your ETA shows up in the status bar (which I admit is neat).

Google Maps at 20

Google Maps launched 20 years ago today. Here’s what I posted at the time:

First impressions. This is frigging amazing, with smooth scrolling and zooming: you’re not constantly reloading pages like in MapQuest. Huge mapping surface. And drop shadows. […] I’m impressed by the detail. They’ve got my area, which is kind of a rural backwater: they’ve got the roads all named, but strangely not the towns. Oh well, data’s rarely perfect—especially when it’s just a beta launch. And for a beta this is awfully impressive.

A flurry of additional announcements followed in quick sucession: the launch of Google Earth, the Maps API that enabled people to build their own maps on top of Google’s interface. The mid-2000s were a busy time for online maps, let me tell you. I had so much to keep up with.

The development and origins of Google Maps, and Google Earth, are the subject of the latest and timely installment of James Killick’s “12 Map Happenings that Rocked Our World.” It seems that the Maps side of things was largely about providing Google search results through a map interface, and when you look at Google’s post commemorating the 20th anniversary, which highlights 20 features of Google Maps, it’s clear how expansive that idea has become.

James also makes reference to a book I somehow completely missed when it came out: Never Lost Again: The Google Mapping Revolution That Sparked New Industries and Augmented Our Reality, an insider history by Google project manager Bill Kilday. (Harper Business, 2018). Amazon (Canada, UK), Bookshop.

Watch Duty

Watch Duty

In the wake of the recent wildfires in southern California, Watch Duty—a simple, free app that provides real-time fire maps and alerts, and which prizes, and is prized for, accurate data, collated by its volunteer reporters—has become the most popular app on the App Store and is being hailed as an essential lifeline: see The Hollywood Reporter, The New York Times, Rolling Stone, The Verge, Washington Post (paywalls on some links).

Some Google Maps Updates

Google Maps imagery updates include improved satellite imagery thanks to an AI model that removes clouds, shadows and haze, plus “one of the biggest updates to Street View yet, with new imagery in almost 80 countries—some of which will have Street View imagery for the very first time.” The web version of Google Earth will be updated with access to more historical imagery and better project and file organization, plus a new abstract basemap layer.

Meanwhile, The Verge reports that Google Maps is cracking down on business pages that violate its policy against fake ratings and reviews.

Online Maps Roundup: August 2024

Apple Maps has launched real-time transit information for Tokyo. Meanwhile, MacRumors takes a look at what’s coming to Apple Maps in iOS 18, with an additional look at the upcoming “search here” function. Google and Waze updates announced at the end of the last month: Google Maps gets easier incident reporting and destination guidance (the building you’re heading to is highlighted on the map); Waze upgrades include new camera alerts, event-based (e.g. concerts and sporting events) traffic notification and reporting, and locked-screen navigation. Also, the Google Maps app now has a simplified tab bar. And they’ve changed the pin design too. What can I say: updates are a little less earth-shattering than they used to be.

Geofence Warrants Found Unconstitutional by One U.S. Federal Court

A U.S. federal court has held that geofence warrants are unconstitutional under the Fourth Amendment, finding that they fit the definition of general warrants that are “categorically prohibited” by that Amendment. EFF, TechCrunch. Geofence warrants, you may recall, require a data provider (usually Google) to identify all users in a given area during a given time period. While ruling them unconstitutional, the U.S. Fifth Circuit Court of Appeal nonetheless allowed evidence collected under a geofence warrant in the case under consideration, citing the good-faith exception, given the novelty of such warrants at the time and the lack of legal guidance available to law enforcement: see the court’s decision.

Geofence warrants are now in something of a grey area: the Fourth Circuit upheld geofence warrants’ legality, at least under certain circumstances, only last month. The two cases may not be an apples-to-apples comparison, but even so the constitutionality of location data searches may take a while (and the Supreme Court, eventually) to sort out.

Terse Directions

Adding to the discussion as to whether online maps’ directions are too exhausting, Tim Bray argues for terse directions: “When I’m navigating an area I already know about, don’t give me turn-by-turn, just give me a short list of the streets to take.”

Right now, Google Maps insists on turn-by turn, with three warnings for each turn. It’s dumb and annoying and interrupts whatever music or show I’m listening to.

What I want is to get in the car and say “Short directions to New Brighton Park” and have it say “Take Main to 12th to Nanaimo to 1st to Renfrew to McGill.” Then when I’m driving, I’d get one vocal warning a block out from each turn, like “Next left on Nanaimo” or some such.

Google Maps Navigation Updates

Google Maps is introducing a speedometer and speed limits to iOS and Carplay; the feature has been on Android since 2019. Meanwhile, Google has pushed back on the claim from one user that pop-up ads were turning up while navigating with Google Maps; rather, they say it was an instance of “promoted pins” that (should) only pop up if tapped on. 9to5Google: “we were able to replicate the exact same UI by tapping on a location on the map, so it seems the screen was either touched by accident or a glitch was at play.”
