Mapping UNESCO’s Intangible Cultural Heritage spots

Looking at the most recent UNESCO Representative List of the Intangible Cultural Heritage of Humanity it’s clear that these “elements,” as they’re called, are all over the map.

There’s painting, weaving, pizza making and spring rituals: but while they offer up videos, photos and text — there’s no actual map of these landmarks in sight.

Making that map shines a spotlight on why organizing data is crucial — and how every organization is a data trove and should be its own best data detective. Plotting visually can inform decision making and highlight patterns – inside trends to be worked into deeper groves or used to recalucate course. The list, according to UNESCO, is “made up of those intangible heritage elements that help demonstrate the diversity of this heritage and raise awareness about its importance.”

Get them into a spreadsheet (more on this below) and a couple of things jump out. First, most of the 2017 picks reside in Europe/Eurasia with a substantial scattering in Asia but only a handful in Africa and South America combined.

The other is that the bulk of 2017 intangibles are rituals of some kind (15) followed by music (8) crafts (7) then dance, food, games (3 each) art (2) and a justice system.  The total adds up to over 33 because they are practiced in more than one country, another reason it’s interesting to connect the dots on a map.

These classifications are mine and while a handful are arguably more than one category (is the “art of crafting and playing a musical instrument” an art, a craft or music?) the obfuscating language does a disservice to these traditions.

The third, following from the other two points, is that the list is profoundly political.

Take two of the 2017 foods. Well, I’m calling them that: technically, pizza isn’t on the list, it’s the “art of the Neapolitan pizzaiuolo.”  (Nowhere in the official entry is the product of this art mentioned.) According to the New York Times, the pizza makers of Naples owe the honor to Pier Luigi Petrillo, an Italian professor and expert in “lobbying theories and techniques,” who has three winning UNESCO bids under his belt — the Mediterranean diet and Zibibbo wine-making in Sicily.

Similarly, there’s “dolma making and sharing” in Azerbaijan. More so than the pizza — whose most classic version mimics the Italian flag — dolmas are one of those foods associated with entire regions rather than a single country. The Oxford Dictionary, for example, defines dolmas as “popular in the Balkans, the Caucasus, and the eastern Mediterranean.” The Encyclopedia Britannica is more restrictive – limiting it to “Middle Eastern and Greek cuisine” yet Wikipedia defines them broadly as “a family of stuffed vegetable dishes common in the Mediterranean cuisine and surrounding regions including the Balkans, the Caucasus, Russia, Central Asia and Middle East.” All note the term hails from Greek/Turkish origins.

It’s hard to say what the consequences of being awarded intangible treasure status are, but in this case it does seem — like Iran, awarded in this round a game called Chogan that Wikipedia re-directs to polo – that they could be contentious.

For someone with more patience: since 2008 when the quest to list intangibles began, there are 470 elements in 117 countries, it’d be interesting to see a good representation of the geographical distribution to date and see what pops out. This Wikimedia map takes a stab at it, but the color coding is eye-crossing at best. (You’ll also notice that neither the United States nor Canada have any intangibles — although they’re UNESCO members, they didn’t join the nominating countries for this project.) Continue reading

Five-minute map: San Francisco’s proposed Uber/Lyft loading zones

If you drive, walk or bike in San Francisco you know what a nightmare the ride-hailing services can be.

And if you use them often you’re probably in the habit of trying to pin yourself on a side street or a big empty parking space/driveway and pray they don’t double park while trying to find you. (Zipping past the anecdotal, it’s been calculated that 45,000 Uber and Lyft vehicles now operating in San Francisco account for more than 200,000 trips a day.)

So now the city is interested in adding ride-hailing passenger pick-up zones in a horse- trading effort to wring more data from these startups.

The San Francisco Examiner reports there are seven proposed “loading zones” and maybe one or two will be piloted. It’s a well-reported story — except that it’s missing a map. The neighborhoods are Hayes Valley, Inner Richmond, Inner Sunset, Noe Valley, North Beach, Marina and downtown.

Five minutes later with Google Maps:

A few things jump out — there’s nothing in the traffic-choked Mission district and two “maybes” downtown. (The mapped one on Howard Street above and another potential one left unmapped since it’s described as “between Howard and Third or Fourth streets.”)

Also, once they’re mapped, if you zoom in it’s apparent that the length of these zones varies widely. The North Beach one looks like road rage waiting to happen.

San Francisco does have passenger loading zones already — white curbs with a time limit of five minutes — which in my armchair estimation (and the name “curbs”) says they’re mostly shorter than the approximately 600 feet (two blocks) of the shortest ride-hailing zones in the Richmond and Sunset…

What’s under the canals of Venice? Old boats, tires and a few surprises

Most visitors to Venice drift through the canals on gondolas taking selfies. But a group of researchers spent seven months puttering along pointing high-resolution multibeam echosounders into the waters instead. About 30 of them in all worked aboard the powerboat Litus, intent on mapping the Venice lagoon to gauge the effects of climate change on one of the world’s most improbable cities.

While what’s under those gray-green waters isn’t exactly surprising — boat parts, old tires and containers — scientists say the underwater elevation mapping (that’s “bathymetry,” for the technically minded) comes at a critical time.

The last 100 years have radically altered the shape and ecological makeup of the lagoon, researchers say: for starters, salt marsh areas shrunk by half and underlying sediment has radically shifted. The “floating city” already struggles to stay above water in the spring and summer floods and relative sea level rise is expected to increase their frequency. The Mose system, with its 78 mobile gates that can hold back almost 10 feet of water, construction launched in 2003 and is said to be near completion in 2018.

“Before the Mose system begins to function, it was important to have a full picture of the bathymetry and currents of the tidal channels and inlets, which are the most dynamic portion of the lagoon,” researchers say in a paper published in “Nature.” They caution that the relatively rapid erosive process could threaten the stability of the “hard structures” (read: priceless palazzos) in the near future and should certainly be periodically monitored.

If you want to dig into the datasets, the scientists from research groups (Ismar-Cnr and Iim) have CC-licensed and made them available online with the paper.

“The data also allows us to identify areas with large dunes at the bottom and adjacent erosion sites that document the most dynamic points in the deep lagoon, where it’s important to cyclically repeat these studies to quantify the movement of sediments,” head of the study Fantina Madricardo says in the press release (translation mine.)

Part of the reason these Venice maps look so trippy (or alarming?) is due to the city’s curious geography, perching atop 118 islands bridged by canals. On most bathymetric maps, deeper waters are represented by soothing darker shades (green, blue, violet) and warmer colors (red, orange, yellow) represent shallower waters. A bathymetric map of the San Francisco Bay by comparison looks, well, a lot more soothing despite its notorious currents.

How to investigate your government through algorithms

Some kinds of reporting-by-the-numbers are anything but lazy. Take investigations looking into algorithms — examining the formulas used by the government to determine who is more likely to commit a crime or how likely your building is to have a fire inspection.

Speaking at the recent International Festival of Journalism, Nick Diakopoulos, assistant professor at the University of Maryland’s Philip Merrill College of Journalism and a member of its Human Computer Interaction Lab, gave a solid primer on how to get started.

He’s been studying the wider reach of algorithms in society, government and industry for about four years, coming at it from a computer science background as a “techie who worked my way into journalism.” Boyish, bespectacled and occasionally prone to professorial turns of phrase like “algorithmic accountability,” Diakopoulos offered a look into the numbers that shape our lives.

Digital mapping finally blossoms for parks and rec

If you went by the maps available today your smartphone, you’d probably think the era of paper maps went out with the Rubik’s Cube.

But the next time you’re in a garden or park, you might come across a group of volunteers huddled around an 11×17 black-and-white printout, hopelessly trying to verify what should be where, clumsily marking it up with pencils and colored highlighters. Their work trails back indoors where it adds to a pile of similar maps that have to be verified (or interpreted?) before changes are put into the data base. They are often printed out and verified again for accuracy.

That’s why around 40 people from zoos, gardens and parks from around the world came to a recent talk to hear how Steve Gensler, GIS manager of the San Francisco Botanical Gardens, and Veronica Nixon of the Desert Botanical Garden in Phoenix are using Collector for ArcGIS to maintaining botanical garden plant records at the ESRI User Conference.

The Associated Press Stylebook weighs in on data journalism

If you write about tech, you’ll find the Associated Press Stylebook is a little bit like Dear Abby. By the time the bouffant-hair-and-matching-handbag set gets around to addressing an issue, it’s often already been answered by collective common sense.

Still, it’s nice to see the venerable news organization writing about data journalism in the same update where it finally relinquishes capitalizing the word internet.

The AP Stylebook entry on data journalism, added 2016-04-19, weighs in at just under 500 words.

It begins with six rules for evaluating a data set that range from the very basic (“What is the source?”) to the kind of deep dive that may prevent you from ever filing the story (“Is there a data dictionary or record layout document for the data set – which would describe the fields, types of data they contain and details and announcing detail as indicated?”) Side note: If you’re looking for an entire book of how to present data facts and figures for journalists, my favorite is still “The Wall Street journal guide to information graphics: the dos and don’ts of presenting data, facts, and figures” by Dona M Wong.

The next section launches into the math of doing data journalism, a reminder that word people are often not numbers people. Or a reminder to all that, yeah, elementary school math is good to know.

“Avoid percentage and percent change comparisons from a small base. Rankings should include raw numbers to provide a sense of relative importance.
When comparing dollar amounts across time, be sure to adjust for inflation. When using averages (that is, adding together a group of numbers and dividing the sum by the quantity of numbers in the group), be wary of extreme, outlier values that may unfairly skew the result. It may be better to use the median (the middle number among all the numbers being considered) if there is a large difference between the average (mean) and the median.”

It heads into more advanced territory with a paragraph on causality, rounding numbers and sample size before winding up with a solid reminder for data-happy hacks: “Try not to include too many numbers in a single sentence or paragraph.”

Now we only have to wait and see how the Stylebook passes judgement on the proper abbreviation for “internet of things.”

Armchair mappers: help prepare for the next humanitarian crisis

Screen Shot 2015-05-07 at 5.05.35 PMKathmandu before and after OpenStreetMap’s humanitarian team dived in.

In just 48 hours after Nepal’s devastating earthquake, thousands of volunteers from around the world helped create maps that guided emergency response teams.

Many of these “digital humanitarians” came from OpenStreetMap, an open source mapping effort. OpenStreet Map launched  Humanitarian OpenStreetMap Team (HOT) in 2010 after the earthquake in Haiti, when the office safeguarding country’s maps pancaked in the 7.0 temblor.

Data points: visualization that means something [review]

Proving a point about data with the author's wedding photos.

Proving a point about data with the author’s wedding photos.

Nathan Yau is a self-appointed cicerone who shows the rest of us around the big, beautiful data visualization world.

A statistician by trade, the likeable, plain-speaking Yau runs And, like all good tour guides, his job is to get you to think about what he’s presenting, not just drop your jaw at the sights.

In “Data Points: Visualization That Means Something,” [public library] Yau wants you to think about sample size — even if he has to show you with a jar of gumballs. To bring home the point about data representing real life, he takes out his own wedding photos. Later in the book, he manages to transform an eye-crossingly dull table of U.S. education stats into 29 different graphics to show how it’s done.

Where in the world can you still send a telegram? [Map]

Telegrams may have gone the way of the steam engine, but there are number of places around the world, from Japan to Mexico, still sending them.

The news about India shuttering its 162-year-old telegram service sounded like the last, labored puff of a country making progress into a bold new era.

So I wondered where people are still using them as a swift, inexpensive means to send condolences and well wishes on important occasions. (An outfit called – what else? – iTelegram took over from Western Union for the U.S., though I can’t remember ever sending or receiving a telegram here.)
