Strava is a mobile fitness tracking app that uses GPS data from phones and watches. It has access to a lot of data, and has been using that data to create a global heat map showing the paths taken by its cycling and running customers. The map’s most recent update, last November, aggregates user data through September 2017. But analyst Nathan Ruser noticed a problem: in places where local Strava use is low, the map can reveal the paths of people from wealthy western countries—for example, soldiers at U.S. military bases overseas, whether they’re patrolling or simply exercising. (U.S. troops are encouraged to use fitness trackers.) Which is to say, suddenly Strava is a security problem. Details at BBC News and the Washington Post.
When your navigation app (e.g. Waze) suggests an alternate route to avoid congestion, that has knock-on effects on the communities you’re routed through, particularly when a lot of traffic gets pushed onto quiet residential streets. That’s the situation in Leonia, New Jersey, the New York Times reports, where later this month the police will be closing some 60 streets to non-local traffic in hopes of routing all that Wazer traffic somewhere else. Some of the somewhere elses aren’t happy with this move, naturally. [Engadget]
Justin O’Beirne’s lengthy analyses of Google Maps and Apple Maps are always worth reading,1 and his latest is no exception. Looking at the rapid proliferation of buildings, areas of interest and other examples of Google’s Ground Truthing program, Justin discovers that Google’s buildings data are a product of its satellite imagery, its places of interest are a product of its Street View data, and its areas of interest (the orange-shaded areas that indicate business districts) are the result of combining those stores of data.
…so this makes AOIs a byproduct of byproducts[.]
This is bonkers, isn’t it?
Google is creating data out of data.
This is slightly more than Google’s competitors are able to match. As always, Justin’s analysis is worth reading in full, and comes complete with before/after animations that make his point visually clear.
Google is rolling out changes to the look of Google Maps: a new colour scheme in which icons for similar points of interest get similar colours (orange for food and drink, green for outdoors), and a map that changes to highlight different things if you’re driving or taking transit. To be rolled out over the coming weeks. More at The Verge.
An experimental feature in the iPhone version of Google Maps that measured the calories burned (and equivalent in mini-cupcakes) when walking a route instead has been pulled due to complaints, TechCrunch reports: the feature couldn’t be disabled, the calorie counts were vague and unhelpful, and it could be actively harmful to users with eating disorders. More at Buzzfeed, Slate and The Verge.
Writing for the Washington Post, Jenny Rough looks at how people get themselves lost hiking, despite having a cellphone or a GPS for directions, and how to get reoriented when lost in the wilderness: by remaining calm, by getting yourself situated, and yes, by learning how to use a map.

The Ordnance Survey’s OS Maps mobile app now has a new augmented reality mode. “Using the phone or tablet’s camera view, hills, mountains, coastal features, lakes, settlements, transport hubs and woodland in the vicinity are identified and labelled. If a label is pressed and there is a data connection, a page of useful information about that location is displayed, including nearby walks, photos and places to stay.” AR is very neat but battery-intensive; nevertheless this strikes me as a very useful application of the technology.

CBC News reports that more than 3,000 indigenous communities in Canada—traditional First Nations reserves as well as treaty settlement lands and urban reserves—have finally been added to Google Maps. For some reason I thought they already were—U.S. Indian reservations have been on Google Maps for some time, after all (their visibility, or lack thereof, was commented on in 2011: here, here and here).
Justin O’Beirne is back with a look at how both Google and Apple Maps have changed incrementally over the past year.
Shortly after I published my Cartography Comparison last June, I noticed Google updating some of the areas we had focused on[.]
Coincidence or not, it was interesting. And it made me wonder what else would change, if we kept watching. Would Google keep adding detail? And would Apple, like Google, also start making changes?
So I wrote a script that takes monthly screenshots of Google and Apple Maps. And thirteen months later, we now have a year’s worth of images […]
It’s cool to see how much Google Maps has changed over the past year. But it’s also surprising to see how little Apple Maps has changed[.]
A new version of Google Earth launched today. Unlike previous versions, the desktop version runs in a web browser rather than a standalone app. Also unlike previous versions, it’s no longer cross-platform: for now at least, the desktop version only runs in Chrome, and the mobile app is Android-only.
Frank Taylor has been covering the new release at the venerable Google Earth Blog and has a first review.
For my part, I’ve poked around in it in Chrome a bit and I found it fairly responsive and easy to use. If it runs this well in the browser I can see how a standalone app would be redundant; this is a better delivery method. I would much prefer it, though, if it also ran on platforms that didn’t belong to Google.
“Windows 10’s stock Maps app has a drawing tool that’s quite useful, especially if you have a Windows 10 touchscreen PC,” writes Matt Elliott at CNet. In addition to scribbling notes, you can draw a line between two points to get directions and measure the distance of a drawn route. My household is all-Apple so I miss out on things like this on other platforms. [Gretchen Peterson]
Google tends to release wacky things around April 1st, as well as some more serious things (like Gmail). Ms. Pac-Maps is one of the former, and the latest strange thing to be added to Google Maps around this time. In the same vein as the Google Maps Pac-Man feature from 2015, it enables you to play Ms. Pac-Man on the road grid in Google Maps, and runs on the most recent Android and iOS apps as well as on the desktop until April 4th.
