An Exhibition of Antique Iowa Maps

Iowa and the Midwest: An Exhibition of Antique Maps, an exhibition of maps of Iowa from four private collections, runs from 12 August to 23 October at Simpson College’s Willis Gallery. (Simpson College is situated in Indianola, Iowa, just south of Des Moines.) “The maps, which date from 1715 to 1902, chart the region’s Euro-American development from unexplored colonial territories to what is now America’s Heartland.” [WMS]

OpenStreetMap at the Crossroads

“The OpenStreetMap Community is at a crossroads, with some important choices on where it might choose to head next,” wrote Michal Migurski last month. Identifying three types of map contributors—robot mappers using third party data, crisis mappers responding to a disaster like the Haiti earthquake, and so-called “local craft mappers” (i.e., the original OSM userbase that edits the map at the community level, using GPS tracks and local knowledge), Michal ruffled many feathers by saying that “[t]he first two represent an exciting future for OSM, while the third could doom it to irrelevance.” That’s largely because, in his view, the craft mappers’ passivity and complacency, and their entrenched position in the OSM hierarchy, are impeding the efforts of the other two groups.

Continental Drift, GPS and Europe

In response to the news that Australia has to correct its GPS coordinates to account for continental drift, the Ordnance Survey blog examines whether Great Britain will have to do the same. “The situation for us (and most of Europe) is not so bad. Europe’s GPS compatible datum, ETRS89, is fixed to the European tectonic plate at the time 1 January 1989 and moves by around 2.5 cm each year. In theory, GPS-derived coordinates are now about 70 cm away from where they should be in the ETRS89 system.”

Louisiana Flooding: NASA Animation of Accumulated Rainfall

louisiana-floods

NASA Earth Observatory: “Days of intense rainfall in August 2016 led to widespread flooding in southern Louisiana, as rivers swelled high above their banks and many crested at record-high levels. […] The animation above shows satellite-based measurements of the rainfall as it accumulated over the southern United States. Specifically, it shows rainfall totals every three hours over the span of 72 hours from August 12-14, 2016. These rainfall totals are regional, remotely sensed estimates, and local amounts can be significantly higher when measured from the ground.”

In Defence of the Mercator Projection

In a June 2015 piece for Al Jazeera America, history Ph.D. candidate Nick Danforth offered a contrarian opinion piece in defence of the Mercator projection. The usual (i.e. Peters) critique of the Mercator is that it emphasizes northern countries at the expense of equatorial countries. Danforth questions the premise behind that critique:

I first sided with the Mercator against its critics when, on one of the rare occasions I thought about Greenland, I realized just how rarely I thought about Greenland. Despite seeing it hanging there like a giant icy sword of Damocles atop every wall map, we just don’t seem to care about it. Antarctica, too, is massively inflated on the Mercator, to the point that it’s as big around as the entire earth. But few would argue that mapmakers intended to depict it as a superpower. Meanwhile, if maps lead us to ignore Africa, they should also lead us to treat cartographically bloated Canada as one of the most important countries in the world. We don’t.

He goes on to argue that if the Mercator projection was a reflection of European power, Africa would have been emphasized, not minimized.

Of all the problems with criticizing the way our maps depict Africa, the most ironic is that it ignores the continent’s history of colonialism. Consider the motives of a colonial-era British cartographer—perhaps the kind of guy who made this bold, colorful propaganda map […] showing off the queen’s dominions.

His incentive, if anything, would have been to make Africa appear as large as possible, since Britain then ruled a large share of it. With India along the same latitude, expanding the size of the earth’s equatorial region would have been a perfect way to color more of the map imperial pink.

Google, Palestine, and the Unbiased Map

As the Disputed Territories site, which catalogues how Google manages various contested borders, points out, “Google’s maps of disputed territories differ depending on who’s looking at them.” As we’ve seen recently with regard to Crimea, that doesn’t always keep Google out of trouble. An online petition asking Google to label Palestine on Google Maps has garnered more than 300,000 signatures since March. The petitioners accuse Google of removing Palestine at Israel’s insistence; but, as the Guardian reports, “the truth is, it was never labelled by Google in the first place.” (The West Bank and Gaza Strip had their labels removed by a bug; Google’s restoring them.)

In a follow-up piece for the Guardian, Leigh Alexander writes:

The swiftness of the backlash, though, is not just about the wish for justice on behalf of an occupied people, but about the belief—now punctured—that our technology is neutral, that it presents an unbiased, infallible version of the world. […]

While it might seem imperialistic for Google to decide how the US should see the rest of the world, perhaps it would be equally troubling to see the company wade into global verdicts on the righteousness of every international occupation. That it allows its sketch of the geopolitical climate to reflect the perspective of who is viewing it, rather than impose the prevailing popular opinion in the west, may not be neutral or unbiased, but it is probably the most fair.

Mapping the Rio Olympics

Fiasco Design’s Rio 2016 Interactive Map (screencap above) is a cheeky game-style enviroment that mixes Olympic venues with local controversies.

What3words, a company that assigns a three-word mapcode to every location in the world—useful in places like favelas that have no formal addresses—has partnered with an official Olympics app, Rio Go (iOS, Android) to provide locations for Rio visitors. More: Reuters, the Telegraph.

A Globe of Percival Lowell’s Mars

pkm-mars-globe

Hand-made globes are increasingly a thing, apparently. As Atlas Obscura reports this week, Michael Plichta’s company, Planetenkugel-Manufaktur, is producing a hand-crafted globe of Mars with a twist: it’s based on Percival Lowell’s maps, which (erroneously) showed the Martian surface covered in canals. It’s delightfully retro and I love it. Here’s a video:

Nowhere on the website is a price mentioned, which tells me that I won’t be able to afford one, damn it.

The Illustrated Map of London

Illustrator Cally Lathey has produced a second edition (I hadn’t seen the first edition before now) of her Illustrated Map of London. This extraordinarily detailed and whimsical hand-drawn map is the result of five months’ effort; this short video chronicles the process.

It’s available as a limited edition print in two sizes, prices ranging from £110 to £140. Maps of central, north, west, southwest, southeast and east London are also available. More about the map at Londonist and Time Out London. [WMS]

Another Look at Persuasive Cartography

Writing for Hyperallergic, Allison Myers explores Cornell University Library’s P. J. Mode Collection of Persuasive Cartography, the collection of propagandistic maps I told you about last January.

“We made significant changes to all of our development processes because of it,” says Cue, who now oversees Maps. “To all of us living in Cupertino, the maps for here were pretty darn good. Right? So [the problem] wasn’t obvious to us. We were never able to take it out to a large number of users to get that feedback. Now we do.”

Indian Railways Reachability Map

Sajjad Anwar and Sanjay Bhangar have been playing with train, station and schedule data from Indian Railways, one result of which (so far) is this reachability map—all the destinations reachable by a single train (i.e., without a transfer) from a given station. [Sajjad Anwar]
