Nick Pannell wants the Ordnance Survey to change the route of the Abbot’s Way path through Dartmoor National Park in Devon, England. Pannell says his own research shows that medieval monks took a more northerly route between Buckfast and Tavistock, and that the path shown on OS maps since 1886 is wrong. The OS doesn’t dispute Pannell’s research, but says that the current route existed 130 years before the initial survey, and there are no currently existing paths along Pannell’s preferred route. This seems to be a case of the prescriptive vs. the descriptive: Pannell shows where the path used to be or ought to have been, the OS shows the current reality on the ground. Nor can OS change the map unless, per the article, Historic England changes the official route: it’s not OS’s call to make.

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.
Adventures in Unpreparedness
Two recent cautionary tales about the risks of going forth without proper navigational tools. First, I’m a bit confused about this BBC News report, which cites what3words as coming through when a boat broke down in the Channel Islands area:
[The rescue service] said although the vessel had no working on board GPS and an inoperative VHS radio, crews were able to establish a position using the location app “what3words”. […]
The coastguard said an operator was able to translate the vessel’s what3words location from a mobile phone into latitude and longitude.
Now hold on: if you’re able to use what3words on a mobile phone to get a fix on your location, it’s because your phone has a built-in GPS, so it’s not like they didn’t have access to GPS. More likely is that they couldn’t figure out how to get lat/long coordinates to rescue services in any other way. (It’s a long press on your location in either Apple Maps and Google Maps, but to be fair, that might not be obvious or easy to figure out for the first time in the middle of a crisis.)
Meanwhile, an unprepared hiker without a map who got lost in New Hampshire will likely be billed for the cost of his rescue.
Topo and Trail Maps Coming to Apple Maps in iOS 18/macOS Sequoia
Topographical maps and hiking maps are coming to Apple Maps on the Mac, iPhone and iPad as of macOS Sequoia and iOS/iPadOS 18, due out this fall. The hiking maps will be at least for U.S. national parks, and will also be available in offline mode because hiking in areas without cell service is the point. Other features coming to Maps include custom walking routes and saved places. [Spatially Adjusted]
Google Maps Called Out for Showing ‘Potentially Fatal’ Mountain Routes
The Guardian: “Scottish mountaineering charities have criticised Google for suggesting routes up Ben Nevis and other mountains they say are ‘potentially fatal’ and direct people over a cliff.” Google Maps’s issue with Ben Nevis is that it routes to a parking lot nearest the summit, then more or less straight-lines it from there; as a dotted line it’s meant to indicate a route very imprecisely, but it also corresponds to a higher-difficulty ascent route that could land even experienced hikers in trouble. Not meant to be taken by people who don’t know what they’re doing—the people who might have no clue that it’s a bad idea to use Google Maps for mountain hiking, for example.
To be clear, I think this one’s on Google. A lot of people trust online maps implicitly because they have poor navigation skills and have a hard time overruling what the directions tell them: this is why people keep driving into rivers and onto tracks. It’s a design failure not to account for this in every circumstance.
Four Articles on Navigating Outdoors
Outside’s Andrew Skurka has posted a four-part series on the skills and tools required to navigate outdoors (remember outdoors?), which in general means knowing how not to get lost. In part one, “A Backpacker’s Guide to Maps,” Skurka recommends what kind of maps to take with you: paper maps, mainly, of various scales, but with digital maps as a backup. Part two, “The Gear You Need to Navigate in the Backcountry,” looks at equipment: not just GPS, but also basics like a compass, altimeter and a watch. In part three, “How to Master Navigational Storytelling,” is about developing a narrative of the route you’re taking to avoid getting lost. Finally, Skurka offers a checklist of skills to test yourself against.

Keith Myrmel’s Hand-Drawn Trail Maps
Keith Myrmel, a retired landscape architect from Minnesota, has produced two maps of the Boundary Waters region that are proving popular with hikers and canoers. The maps—one of the Superior Hiking Trail, the other of the North Country Trail and Arrowhead region—are large (26 by 40 inches) and intricately hand-drawn. The Twin Cities Pioneer Press covered Myrmel and his work last June:
“It’s fascinating how many people are map lovers,” Myrmel said. He has an extensive collection of Boundary Waters Wilderness maps dating back to the 1950s. “I said, if I’m going to do this, I’m going to do this old-school style. It’s all by hand.”
Using pencils, markers and watercolor paint, he put down information from books, maps, the internet and personal experience on a 2-by-13-foot map. The process took hundreds of hours, he said.
See also this 2018 story from the Star Tribune. The maps cost $34 or $35 and are available for sale from Myrmel’s website or from a number of local businesses.
Purple Lizard Maps
Every now and again I discover another local mapmaking company whose products are familiar to, even well-loved by, well, the locals, but not much known elsewhere: the A-Z maps and London; the Maine Atlas and Gazetteer; Kroll and Seattle; Wunnenberg and St. Louis; Sherlock and Winnipeg (that one I knew about, being from there). Add another company to that list: Purple Lizard Maps, which produces a line of outdoor recreation maps that focuses mostly (but not exclusively) on central Pennsylvania. The Center County Gazette talks to Michael Hermann, who founded Purple Lizard in 1997. [WMS]

The Least Popular Ordnance Survey Map
The Guardian reports on the worst-selling Ordnance Survey map, which I suspect will very quickly cease to be the worst-selling map thanks to the news coverage. It’s OS Explorer 440: Glen Cassley and Glen Oykel, a 1:25,000-scale map of a remote region of the Scottish Highlands. (Buy it at Amazon.) The area covered by the map is apparently spectacularly empty, at least as far as humans are concerned, with only “a few dozen houses,” most of which are used for vacation or hunting purposes. In a blog post today, the Ordnance Survey goes into more detail, listing the 10 least popular maps in the U.K.: they’re all in Scotland, so they also give the least popular maps for England and Wales.
If the purpose here is to point to the route less travelled, well and good, but I suspect the effect will be rather like what happens when a travel guide raves about an out-of-the-way, hidden gem of a restaurant.
Gatineau Park Recommends Paper Maps
Relying on your smartphone’s maps can be risky in places where cellular service is patchy. That goes for Gatineau Park, where, despite the fact that its southeast corner is surrounded by the city of Gatineau, Quebec (across the river from Ottawa), staff still recommend people use paper maps, CBC News reports. It’s a big park, after all, and not all of it is in the city. But it’s not just about dead zones and dead batteries: out of date trail information and lack of trail difficulty are also problems. None of these problems, mind you, are unfixable (except, you know, dead batteries).
The paper maps in question include general summer and winter maps, along with trail maps for summer and winter activities (all links to PDF files). They’re not total luddites: here’s an interactive map.
A Mobile Mapping Roundup

Traffic. Traffic congestion is a key feature of mobile mapping, and predicting it involves looking at historical data. CityLab reports on a recent study suggests that time-of-day electricity usage patterns can be used to predict traffic congestion patterns. A household that starts using power earlier in the morning gets up earlier and presumably will go to work earlier.) It’s another variable that can be put to use in traffic modelling.
Trail difficulty. OpenStreetMap doesn’t differentiate between “walk-in-the-park” trails and mountaineering routes, and that may have had something to do with hikers needing to be rescued from the side of a British Columbia mountain recently. The hikers apparently used OSM on a mobile phone app, and in OSM trail difficulty is an optional tag. The wisdom of using OSM in safety-critical environments notwithstanding, this is something that OSM editors need to get on. [Ian Dees]
The Ordnance Survey Launches a Line of GPS Devices
Now seems an odd time to be launching a line of standalone, single-purpose GPS devices, but the Ordnance Survey has gone and done so: they’ve announced a total of four devices, ranging in size from the cycling-friendly Velo to the robust Aventura and in price from £370 to £500. The OS has been offering third-party devices from the likes of Garmin and Satmap through its online store; it’ll be interesting to see how people see these as measuring up against those devices—or against an app on the smartphone they may already own. More at Road.cc.
A Paper Maps Roundup
Suddenly I’ve got several links in the queue about paper maps and the use and making thereof:
The Daily Telegraph links a record year for rescues of climbers and walkers in the Lake District with a lack of preparedness and an inability to use a paper map and compass. [The Meek Family]
BBC Autos looks at something that ought to be obsolete in the age of onboard navigation and mobile phones: the AAA’s TripTik. “And yet? July 2016 was the most popular TripTik month in AAA’s history, issuing 2 million TripTiks to members in a single month.” Go figure. [Osher]
The BBC also has a short video on mapmaker Dave Imus, who describes himself as a “geographic illustrator” and describes mapmaking as an art rather than a science. [WMS]
I hadn’t know about Wunnenberg’s street guides, because I’m not from St. Louis, but I’ve seen other products of the sort: locally produced, hyper-detailed maps of a specific area. (Think the A-Z Maps and London, or Sherlock Maps and Winnipeg.) The St. Louis Post-Dispatch has a look at Wunnenberg’s in the context of GPS, mobile phones and declining paper map sales. [WMS]
The Ordnance Survey Maps Britain’s Favourite Routes
The Ordnance Survey has created a series of data visualizations showing the most popular walking and cycling routes, based on OS Maps usage. “The 500,000 plus routes were illustrated in a series of beautiful data visualisations by [cartographic designer] Charley [Glynn], who found it amazing that the people who created routes for their outdoors adventures had logged almost every bit of British coastline. It neatly frames the rest of the data and gives the illusion you are looking at a map of Great Britain. The darker, thicker areas illustrate the higher concentration of routes and reveal popularity.” Flickr gallery. [Mountain Bike Rider]
The California Hiking Map
The California Hiking Map is a poster-sized (40″×60″) map of California that purports to show all of the state’s hiking trails on a single map. “The trails shown generally include hiking trails, Class 1 bike paths, and fire roads closed to vehicles. This map also highlights select long distance trails and historical trails. Insets were made for some areas that have a high volume of trails in close proximity.” The result of two years work and a Kickstarter campaign, the map costs $20 plus tax and shipping. [Ryan Mik]
