Alex McPhee’s ridiculously detailed map of Alberta, which included things like the area burned in the 2016 Fort McMurray fire and the province’s Hutterite colonies, came out in print form—specifically, in the form of a 42″×68″ wall map—last year. Now he’s done it again: a similarly detailed 36″×66″ wall map of his home province of Saskatchewan, which he’s just sent to the printer. Each map starts at $60.
Flooding in Pakistan
The satellite imagery of the flooding in Pakistan is insufficient to grasp how widespread the devastation is, unless you zoom out enough (which you can do at the MODIS page). The imagery focuses on the flood plain of the Indus River: it covers most of Sindh province and a good chunk of Baluchistan. See The Washington Post’s maps for perspective. The Earth Observatory and MODIS pages, as well as the CNN article, have before/after image sliders: Earth Observatory compares the situation to three weeks ago, the other two to last year.
Update, 1 Sept:
The ESA has released the above image based on Copernicus Sentinel-1 data. More than a third of Pakistan is now under water.
Update, 3 Sept: The Guardian has more before/after imagery.
Mapping ‘The Spear Cuts Through Water’
At Tor.com, Simon Jimenez talks about the map that accompanies his upcoming epic fantasy novel, The Spear Cuts Through Water. It’s not a map that follows the default fantasy map design by any stretch. He starts with the map, drawn by Chris Panatier.
There is no compass rose for orientation, no place names, no handy scale for distance ratios so that a reader might be able to tell how far one location is from another. There are barely even locations. Even the perspective is different—not a bird’s eye view, but something closer and more intimate, for a better view of the imagery that leans away from literalism and more towards the metaphorical, and the eerie.
Because of all of these choices, it is not a particularly useful map. One would be hard-pressed to use it as a reference tool as they journeyed with the characters through the book. This is by intention.
Jimenez explains how he grappled with the idea of mapping, and of fantasy mapping, when decided whether, and how, to include a map in his book. Very insightful and worth reading (and I’m not just saying that because he name-checks me at the end).
Remotely Operated Vessel Maps Tonga Caldera
As part of the Tonga Eruption Seabed Mapping Project, a robotic vessel has conducted a bathymetric survey of the Hunga Tonga-Hunga Ha‘apai volcano’s underwater caldera. Said volcano, you will recall, erupted spectacularly last January. The 12-metre vessel, USV Maxlimer, was controlled remotely from 16,000 km away, and carried sensors to measure the state of the seabed, temperature, salinity, turbidity, dissolved oxygen and chemical plumes. More at the press release. BBC News coverage.

Mapping Drought in Europe
The European Drought Observatory maps drought the way meteorologists map extreme weather: it maps watches, warnings and alerts based on a lack of rainfall, a lack of soil moisture, and stress to vegetation following a lack of moisture, respectively. In addition to the online map viewer, there is a comparison tool and a way to generate your own maps from the data, among other tools. As of early August, the Observatory says, 47 percent of EU territory is facing warning conditions, 17 percent in alert conditions. It’s been a bad summer. [Maps Mania]
Mapping the Watery Past of Mars
A new map of Mars reveals the abundance of aqueous minerals—clays and salts that form in the presence of water—that were created during the planet’s distant watery past. “The big surprise is the prevalence of these minerals. Ten years ago, planetary scientists knew of around 1000 outcrops on Mars. This made them interesting as geological oddities. However, the new map has reversed the situation, revealing hundreds of thousands of such areas in the oldest parts of the planet.”
Another Onion Riff on Fantasy Novels and Maps
The Onion: Underwhelming Fantasy Novel Starts With Map Of Ohio. “Feeling let down to see a straightforward rendering of the Midwestern state, local reader Kyle Nuebart reported Friday that underwhelming fantasy novel Dayton Rising featured a map of Ohio in its opening pages.” I’m impressed that they went to the trouble of creating a fantasy map of Ohio to illustrate a one-joke article (admittedly, it’s a really good joke).

I’ve just added quite a few more titles to the Map Books of 2022 page, which lists all the map, cartography and geospatial related books scheduled to be published this calendar year. I try to keep this page as comprehensive and as up-to-date as possible, so please let me know if there’s something I should add to the list.
Online Map Roundup for August 2022
Google Maps sends people looking for abortion providers to so-called crisis pregnancy centres, which discourage the procedure, Bloomberg reports.
Also in Bloomberg, Mark Gurman discusses Apple’s plans to expand its advertising business, which apparently includes adding ads to Apple Maps.
Apple’s cycling maps now include Hawaii, and its detailed 3D cities now include Atlanta, Miami and Seattle. They’re also testing their upgraded maps in Israel, Palestine and Saudi Arabia.
Google Maps updates outlined in a blog post last month include cycling route information, location sharing, and photorealistic aerial views of major landmarks.
Instagram announced a searchable map feature last month, expanding its map feature beyond geolocating posts. This, after a Google VP noted that young users are using apps and TikTok for discovery purposes rather than Google’s Search or Maps. You wouldn’t think that Instagram and TikTok qualify as map apps, but the street finds its uses.
Esri Pays $2.3 Million in Back Wages to Resolve Pay Discrimination Case
Esri has agreed to pay $2.3 million in back wages and will review its compensation system and provide training as part of a conciliation agreement with the U.S. Department of Labor, the department announced yesterday. The case dates to 2017, when, in the course of a federal compliance evaluation, the department alleged that Esri engaged in systemic pay discrimination, paying 176 female employees less than their male counterparts. Esri entered into the conciliation agreement voluntarily.
UKHO to Discontinue Paper Nautical Charts by 2026
The U.K. Hydrographic Office plans to withdraw its paper nautical charts from production by 2026, citing “a rapid decline in demand for paper charts” relative to their digital navigation products. Press release.

How Far Can You Go in Five Hours? Or on a Single Train?
Benjamin Tran Dinh (previously) has built an interactive isochrone map of Europe that shows you how far you can go by train from a given station in five hours (assuming a connection time of 20 minutes, which is an approximation: generous if same-station, less so if you have to cross the city). The map updates as you move the pointer across it, which is a lot of fun.
The isochrones are generated from data from the direct.bahn.guru site, a site that is worth looking at in and of itself: it shows all the direct connections from a given station, i.e., everywhere you can get to on a single train. That site, in turn, gets its data from the Deutsche Bahn via a legacy API that is necessarily incomplete and only covers destinations reachable from Germany. But there are no complete datasets of European transport routes, so this’ll do. [Maps Mania]
RMTransit on Navigating Transit on Your Phone
Transit is an entirely different paradigm, and transit systems and their data are more complex and less standardized: these are among the reasons, Reece argues in today’s RMTransit video, why using your phone’s mapping app to navigate while using transit is a less satisfying experience than it is when driving, or even walking or cycling.
GPS Negatively Impacts Spatial Memory
Rebecca Solnit points to a 2020 study that attempts to measure the impact of using GPS navigation devices on our spatial memory. After assessing 50 drivers, researchers found that drivers with more GPS experience had worse spatial memory when navigating without GPS. But more significantly, it’s a longitudinal study: 13 of the participants (admittedly a small sample) were retested three years later, and greater GPS use correlated with a steeper decline in spatial memory.
This is a single study, and a small sample, so I’m hesitant to draw firm conclusions. And in any case it’s not necessarily a surprising conclusion: the more you rely on a tool, the less able you are to do without it. Well, yes. When we talk about how GPS is destroying our ability to navigate or read a map, there is a presumption that this is an objectively bad thing. Except that I’ve encountered too many people who couldn’t navigate their way out of a bag before GPS. A lot of people who let their GPS receivers get them lost were, I think, pretty good at getting themselves lost without it.
The question isn’t whether GPS use atrophies an individual’s ability to navigate: that’s like worrying that a calculator reduces your ability to do sums in your head, or that a word processor excuses you from knowing how to spell. Of course it does. Those of us who are good at navigation (or sums, or spelling) and think an important skill is being lost will clutch our pearls, but making something easier also makes it more accessible. The question is whether people are, on balance, at a societal level, getting lost less often. That’s not a question neuroscience can solve, nor something you can test with an fMRI. I’m not sure how to measure it, or even if it can be measured. But I’d love to find out.

New Osher Exhibition: Vacationland
Vacationland: Mapping History in Maine, the Osher Map Library and Smith Center for Cartographic Education’s latest exhibition, “looks at tourism through the lens of travel and transportation, quite literally the mapping of tourism in Maine from the mid-19th century to the mid-20th century. This exhibition invites you to think about the changing landscape interventions created by and for tourists, as well as the impact such changes had on people living in Maine year round, and upon the environment.” This exhibition opened on 15 June and runs until 11 October; reservations required for social distancing reasons to visit the gallery in person. It’s not yet online; the Osher usually gets an online version up a little later on.
