The Map Room - A Weblog about Maps
The USGS's California Seafloor Mapping Program has produced a set of insanely detailed maps of the sea floor along the California coast. Downloadable as rather hefty PDF files; the map sheets are three feet across as paper maps. Above, a detail from the shaded-relief bathymetry map of the San Francisco area. Boing Boing, Wired.
I sometimes get asked how to do a fantasy map. I'm the wrong person to ask, because I'm basically a fantasy map critic, not a working illustrator. What the people asking me this question want is an instruction manual for the standard fantasy map, and for that, Roberts is their man, because he's an actual illustrator. He does operate within the dominant fantasy map paradigm I often critique (though with a good deal more colour and texture than the standard line drawing), but he does it very well, and more importantly shares his methods. Roberts's blog is full of interesting material on how he goes about creating fantasy maps: see for example this tutorial.
Google Maps had to apologize again last week, this time because searching for racist terms gave results like the White House and Howard University. The results were derived from online discussions: idiots using an offensive term to describe a place associated the term with the place in Google's search algorithms. Google says it's changing the algorithm to fix the problem (because algorithms are to Google what procedures are to bureaucracies -- the source of, and solution to, all life's problems).

A Redditor called Sarithus has created a map of Clichéa, "a map based on fantasy tropes that also pokes a little fun at unoriginal map makers." Like others of its kind, it hearkens back, probably undeliberately, to early modern maps of Cockaigne and Schlaraffenland and other satirical maps. Cartographer's Guild thread, Reddit thread.

Google is temporarily suspending Map Maker, its tool allowing user contributions to Google Maps, until they fix their edit moderation system. Auto-approvals of map edits had been suspended in the wake of the notorious and high-profile edits to the map near Rawalpindi; since then edits to the map have required manual approval, which has created a massive backlog. "We believe that it is more fair to only say that if we do not have the capacity to review edits at roughly the rate they come in, we have to take a pause." Via The Verge.
While looking for something else, I stumbled across the Manitoba Infrastructure and Transportation Ministry's Historical Highway Maps of Manitoba site: a collection of PDF scans of dozens of highway maps of the province. The earliest is a 1926 map produced by the Winnipeg Tourist and Convention Bureau; the most recent is the B version of the 2010 Official Highway Map. Collectively they trace the development of the province's road network: I got so very lost in this site watching the road network change from year to year -- just as I did as a child, when I studied each new edition to see what had changed from the previous year. This is a weapons-grade hit of nostalgia for me.
Above, a detail from the 1966-1967 map, the first to use the style of map that I was familar with growing up in the 1970s.

Some embarrassment for Google Maps last week, as they were forced to apologize for an image of the Android mascot peeing on an Apple logo that turned up on the map near Rawalpindi in Pakistan. To say nothing of the phrase "Google review policy is crap" etched into nearby Takht Pari Forest. Both have since been removed. Boing Boing, the Guardian, The Verge.
To be fair to Google, crowdsourcing map data does have its pitfalls: OpenStreetMap has to deal with this sort of thing all the time. You have to have something in place to deal with bad-faith edits. None of the edits I've made to Google Maps went through without someone reviewing them, so I'm surprised that this could happen. That said, when you need your map updated fast (such as during natural disasters like yesterday's earthquake in Nepal), it's hard to beat crowdsourcing.
As always, it's important to keep in mind that all online maps have their shortcomings.
The federal government's new map of Canada, part of the Atlas of Canada reference series, came out this week. Among the changes between it and its predecessor (which came out in 2006), one in particular is drawing attention. Ivan Semeniuk in the Globe and Mail:
Whereas the older version of the map showed only that part of the sea ice that permanently covered Arctic waters year round at that time, the new edition uses a 30-year median of September sea-ice extent from 1981 through 2010. September sea ice hit a record low in 2012 and is projected to decline further. The change means there is far more ice shown on the 2015 version of the map than on its predecessor.
The changes can be seen below: the 2006 map is on the left, the 2015 map on the right.
Now as Semeniuk's piece points out, neither way is wrong. But all maps have a point of view, and it's naive to think that this change was made in a value-neutral environment: this was the result of a conscious decision. The reason for that decision -- that's what's interesting.
Two stunning maps of the Moon have been released by the USGS, both based on data collected by the Lunar Reconnaissance Orbiter: one an image mosaic assembled from visual imagery, the other (above) a colour-coded topographical map derived from laser altimeter data. Via io9.
- Dawn's first colour map of Ceres: map-projected false-colour images of the dwarf planet taken as the spacecraft approached, assembled from images taken through blue, green and infrared filters. (Previously: At Ceres.)
- An elevation map of the Ares Vallis region of Mars (above) from the DLR, the German space agency (via io9).
- A map of known exoplanets in the Milky Way; most of them were found during the Kepler mission, which pointed at a a particular region of space.
Alastair Bonnett's Unruly Places (first published in the U.K. as Off the Map) is a light, entertaining exploration of some of the world's more unusual places. Bonnett, a social geography professor at Newcastle University, has written 47 short essays about locations that, in the grand scheme of things, don't make any sense: the exceptions, the asterisks, the ink blots (in at least one case literally) on the map.
These range from the deeply frivolous to the profoundly injust: from bits and pieces of New York City transformed into environmental time capsules and art projects to places meaningful to the author; from rendition sites and pirate bases to Bedouin settlements in the Israeli Negev desert; from destroyed landscapes to Potemkin cities. The places often feel almost science-fictional; and in fact several of them evoked settings in existing science fiction works, like Christopher Priest's Dream Archipelago and Maureen McHugh's Nekropolis.
All in all, a pleasant diversion for the geographically minded, though I did have one quibble: the book calling latitude and longitude "Google Earth coordinates," as though degrees are as proprietary as limited to the KML format.
Emily Garfield's art is a pen-and-watercolour exercise in the cartography of imaginary places. Her drawings "are inspired by the visual language of maps, as well as the fractal similarity that cities share with biological processes such as the patterns of cells and neurons."

Google Maps turned 10 years old on Sunday -- a milestone observed by Samuel Gibbs in the Guardian. See also Liz Gannes's retrospective at Re/Code. My reaction on launch day was pretty effusive -- I was blown away mainly by the user interface. But it wasn't immediately dominant: it took roughly four years for Google to surpass MapQuest in traffic.
Meanwhile, the Pro version of Google Earth, which used to cost $400/year, is now free. Google Earth itself launched in June 2005, so is approaching its own 10-year anniversary, but it began its existence a few years earlier as Keyhole EarthViewer 3D.
Speaking of map anniversaries, National Geographic Maps is marking its centennial.
The photo above marks another anniversary: It shows Apollo 14 astronaut Ed Mitchell consulting a map during his second lunar EVA on February 6, 1971. Apollo 14 returned to Earth 44 years ago yesterday.
Someone was responsible for the maps developed for the film adaptations of The Lord of the Rings, The Hobbit and other movies (on-screen and in promotional materials), and that someone is Daniel Reeve, a freelance artist who also did a lot of the letterwork and calligraphy. Via Boing Boing.
