Greenland Gains Self-Government from the Kingdom of Denmark, Kinda (Economist)

July 1st, 2009

2609ww2[Editor's note: What is a country? A nation? A nation-state? By some counts, there are about 195 "countries" or 194 (US State Department) in the world, but by others like the ISO and United Nations, about 245 which includes extra "regions" for statistical reasons or FIPS code assignments. The World Bank (2) says 186 or 210. How can there be such a wide spectrum of valid answers? The issue is complicated by historic colonial relationships with overseas dependencies and affiliated political administrative units, and by the non-uniform way different "countries" sub-divide themselves.

For instance, France considers all it's "dependencies" unitary parts of France, while the U.S. does not view it's own territories equal to states vis-a-vis constitutional rights. But some unitary parts of France outside mainland Europe get treated differently from Metropolitan France by the European Union (they don't necessarily get an E.U. passport).

This week, Greenland steps closer to becoming one of the club of 195 "countries" in the world, but really it's just getting more quasi-self-government (sticking in the 245 bracket) within the Kingdom of Denmark's administrative umbrella (which is and is not the same as the "country" of Denmark) for defense and foreign policy.

The higher number doesn't even address sub-national semi-autonomous entities like the United Kingdom's England, Scotland, Wales, and Northern Ireland which fall somewhere between what we in the U.S. think of as "states" and "provinces" (1st order admin units) and those top level countries and nations. Nor does it address disputed or break away regions like Abkhazia.

For Natural Earth Vector, we will include groupings at both "top-level" views (about 195 and 245), and at the 1st order admin (state, province, over 3,000). We will also include a sample of sub-national areas and disputed, breakaway areas.]

New Global 30m DEM Topographic Data via ASTER (NASA)

June 30th, 2009

pia12090-browse

[Editor's note: NASA and Japan's Ministry of Economy, Trade and industry (METI) released new 30 meter resolution Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) to the worldwide June 29, 2009. The new dataset covers the high latitudes with increased precision over SRTM, although the cloud cover problems that plauge ASTER can prove problematic. The servers were being hit heavy on Monday and data download is convoluted. The preview of the data uses a curious data exploration color ramp with inverted shading. Thanks Tom and Laris!]

PASADENA, Calif. – NASA and Japan released a new digital topographic map of Earth Monday that covers more of our planet than ever before. The map was produced with detailed measurements from NASA’s Terra spacecraft.

The new global digital elevation model of Earth was created from nearly 1.3 million individual stereo-pair images collected by the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer, or Aster, instrument aboard Terra. NASA and Japan’s Ministry of Economy, Trade and Industry, known as METI, developed the data set. It is available online to users everywhere at no cost.

“This is the most complete, consistent global digital elevation data yet made available to the world,” said Woody Turner, Aster program scientist at NASA Headquarters in Washington. “This unique global set of data will serve users and researchers from a wide array of disciplines that need elevation and terrain information.”

According to Mike Abrams, Aster science team leader at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., the new topographic information will be of value throughout the Earth sciences and has many practical applications. “Aster’s accurate topographic data will be used for engineering, energy exploration, conserving natural resources, environmental management, public works design, firefighting, recreation, geology and city planning, to name just a few areas,” Abrams said.

Previously, the most complete topographic set of data publicly available was from NASA’s Shuttle Radar Topography Mission. That mission mapped 80 percent of Earth’s landmass, between 60 degrees north latitude and 57 degrees south. The new Aster data expand coverage to 99 percent, from 83 degrees north latitude and 83 degrees south. Each elevation measurement point in the new data is 30 meters (98 feet) apart.

“The Aster data fill in many of the voids in the shuttle mission’s data, such as in very steep terrains and in some deserts,” said Michael Kobrick, Shuttle Radar Topography Mission project scientist at JPL. “NASA is working to combine the Aster data with that of the Shuttle Radar Topography Mission and other sources to produce an even better global topographic map.”

NASA and METI are jointly contributing the Aster topographic data to the Group on Earth Observations, an international partnership headquartered at the World Meteorological Organization in Geneva, Switzerland, for use in its Global Earth Observation System of Systems. This “system of systems” is a collaborative, international effort to share and integrate Earth observation data from many different instruments and systems to help monitor and forecast global environmental changes.

NASA, METI and the U.S. Geological Survey validated the data, with support from the U.S. National Geospatial-Intelligence Agency and other collaborators. The data will be distributed by NASA’s Land Processes Distributed Active Archive Center at the U.S. Geological Survey’s Earth Resources Observation and Science Data Center in Sioux Falls, S.D., and by METI’s Earth Remote Sensing Data Analysis Center in Tokyo.

Aster is one of five Earth-observing instruments launched on Terra in December 1999. Aster acquires images from the visible to the thermal infrared wavelength region, with spatial resolutions ranging from about 15 to 90 meters (50 to 300 feet). A joint science team from the U.S. and Japan validates and calibrates the instrument and data products. The U.S. science team is located at JPL.

Cutthroat Capitalism: An Economic Analysis of the Somali Pirate Business Model (Wired)

June 30th, 2009

[Editor's note: It's been a while since I've seen gradient country fills (!) on a map but this month's Wired magazine obliges with their highly stylized map of piracy off the Somalia coast. The Flash version of the print graphic has a nifty approach to panning the zoomed image, but beyond the novelty is not an effective navigation tool, especially with the single zoom in level.]

Republished from Wired.

Most of Somalia’s modern-day pirates are fisherman who traded nets for guns. They’ve learned that ransom is more profitable than robbery, and rather than squandering their loot, they reinvest in equipment and training. Today, no ship is safe within several hundred miles of the coast.

Placename conventions: Wales (Cymru) @ 2009 Smithsonian Folklife Festival in Washington, D.C.

June 29th, 2009

img_1008_2 img_1011_2 img_1012_2

[Editor's note: Visiting the Wales section of this year's Smithsonian Folklife Festival (continues thru July 5),  I am reminded of how each language has a different name for the same set of geographic features. This is mostly true on the world scale for countries, oceans, continents and so on. Sometimes it continues down to major cities within a certain country, especially with names like "New York". Each language has a "conventional" name for foreign placenames that may or may not bear an obvious resemblance to the name used by the local language used by those in that place. Some cities even have historic (no longer used) conventional names: Istanbul (not Constantanopal). Mumbai took a good 15 years to replace the US-English conventional for Bombay in India.

The technical terms for this, definitions courtesy Wikipedia, are Exonym (a name for a place that is not used within that place by the local inhabitants), endonym, autonym (the name used by the people or locals themselves). Exonyms may derive from distinct roots as in the case of Deutschland, Germany. They can also be cognates which sound similar (and are spelled similar, using the local script), and final they may be fully or partially translated from the native language (like New York and Neuvo York). Transliteration is the practice of converting a text from one writing system into another in a systematic way. Some places, like New Zealand, have multiple local language names for the same geographic features, further clouding the issue.

The US-English conventional romanized script for the country in Europe that borders France and Poland is "Germany" yet in Welsh it is "yr Almaen", which is similar to the usage in French and several other European languages. These types of naming styles are important when attributing a world base map (see Natural Earth Vector blog post). For an audience that is mono-lingual, it makes sense to use conventional names for foreign place names. But what happens for a product that enjoys multi-lingual users? On one hand we want to be "localized" to the appropriate name in each language, but we need to provide enough "conventional" placenames for the user to orient themselves, especially when the foreign names use a completely different writing script (not roman ABCs). Google Maps-US takes an hyprid approach where names in each country are labeled in the local script using the local name, with a few labels also in conventional US-English. When one searches for Tokyo, the map shows Japan in mostly Kanji script with some romanized, conventional US-English versions of those names.

For Natural Earth Vector, we follow a hybrid approach that will allow for localization into other languages besides the compilation language, US-English. Tom Patterson used the following guidelines for his original Physical Map fo the World project, which this project uses as it's primary source:

• Endonyms (Appennino) were favored over exonyms (Apennines) for place names based on Romance and Germanic languages, which are often cognates of familiar English names and easy to identify.
• For other languages, transliterated names of major features (mountain ranges, plateaus, deserts, etc.) received English place name descriptors. For example, Verkhoyansk Khrebet in Russia is labeled on the map as Verkhoyansk Range. Smaller physical features, such as mountains within ranges, have entirely local names.
• Transnational features named in more than one language, for example, the Donau/Duna/Danube River, received conventional English names.
• When two or more countries claim ownership of the same physical feature and use different names for it, the preference was for the country currently in possession of the feature regardless of the circumstances. For example, the southern Kuril Islands that Japan and Russia both claim, and which Russia has occupied since 1945, have Russian names.
• A few notable places have English translations in parentheses, for example, Rub al Khali (Empty Quarter).
• All river names dispense with the word "River" or the abbreviation "R."
• Island names within compact island groups drop the word "Island" or the abbreviation "I."
• Non-English place names have accents and diacritical marks. However, the font used on the map (Adobe Frutiger) lacked a few exotic accents for consonants, which consequently do not appear on the map.

And now for the Welsh Smithsonian Festival information:]

Wales (Cymru in Welsh) is a dynamic and resilient nation. The industrious and resourceful nature of its people provides a firm platform from which to present its rich culture and heritage. Wales Smithsonian Cymru will celebrate language, literature, and the spoken word, present crafts and occupational skills, share music and cooking, and evoke the spirit that powered the industrial revolution and is now championing sustainable solutions. The program will explore how age-old knowledge, skills, and materials continue to be refashioned, recycled, and reinvented to meet modern demands and to continue to connect Wales to the world.

With much of its border being coastline, Wales’ maritime influences remain vital to the nation’s evolution. The mountain ranges and National Parks sustain the rural communities and outdoor life that are Wales’ touchstones. The essence and inspiration of the landscape will be shared by those who live off and nurture Wales’ beguiling natural environment. Cooking demonstrations will explore the qualities of fresh, local ingredients sourced from farmers markets and savored across the country, from seafood platters to hearty Welsh lamb dishes. Performances and workshops will illustrate the diversity of the Welsh music scene, from the ancient sounds of the crwth and pibgorn, to evocative vocal and harp renditions, and to lively folk bands playing a range of familiar and experimental repertoires. Craftspeople and building arts experts will share their experiences and skills working with native Welsh woods, slate, wool, metal, and stone.

Immigration and an international perspective have enriched Welsh culture for generations, while the strength of the Welsh language, which stems from the sixth century, continues to underpin the nation’s identity. Visitors will be able to practice Welsh phrases and learn about the history of the language. In addition to the Festival, Wales’ presence will be extended through ancillary programs that will begin in March 2009, presented in collaboration with partner organizations in Washington, D.C. These activities and events will include a wide range of contemporary arts and a focus on sustainable living and climate change.

Using Data Visualization as a Reporting Tool Can Reveal Story’s Shape (Poynter)

June 26th, 2009

[Editor's note: My colleague Sarah Cohen at The Washington Post was recently interviewed by Poynter about creating data visualizations to help readers understand and reporters research complicated stories. Sarah is on her way to a big new gig at Duke University.]

Republished from Poynter.
By Steve Myers at 6:12 AM on Apr. 14, 2009

Readers have come to rely on interactive presentations to understand complicated stories, using them to zoom in on periods of time and highlight areas of interest. Yet to investigate these stories, reporters often create what amounts to handcrafted investigative art: flow charts with circles and arrows, maps shaded with highlighters and stuck with pins.

More and more, though, some reporters are using data visualization tools to find the story hidden in the data. Those tools help them discover patterns and focus their reporting on particular places and times. Many of the presentations, which can have rough interfaces or less-than-sleek design, are never published.

At the recent National Institute for Computer-Assisted Reporting (NICAR) conference, Sarah Cohen, database editor for The Washington Post’s investigative team — and recently named professor of computational journalism at Duke University — showed how reporters can use interactive graphics for their exploratory reporting. [PDF]

Cohen described this approach to me via e-mail. Here’s an edited version of our exchange.

Steve Myers: How would creating a digital, visual representation of data help a reporter? What does it tell you that you wouldn’t be able to find otherwise?

Sarah Cohen
Sarah Cohen

Sarah Cohen: The same way that visualizations and graphics help readers cut through a lot of clutter and display dense information in an efficient way. The most common things that early visualizations help with are place and time — two of the most important elements in reporting a complex story. Those two things are really hard to see in text. They’re really, really hard to see in combination. So the graphics can show you where to go to find your subjects or where to go to find the most typical subjects. They can also show you when the story you are trying to find peaked. Put them together, and you can start finding the very best examples for your story.

That’s pretty general, so let me give you a couple of examples. During a story on disaster payments in the farm subsidy system, we wanted to make sure that we went to places that had received the payments year after year after year. Using a database, we could find farms that had received multiple payments pretty easily. But looking at repeated images of density maps that I made of the payments, it was really obvious where to go — specific areas of North Dakota and Kansas.

Crop payments

Cohen used density maps to figure out what areas of the country had received disaster payments year after year.


In another example, we were working last year on a story on practices used by landlords to empty their buildings, partly in order to avoid strict laws on condo conversions (visualizations: research version, published version. We knew one neighborhood of the city was Ground Zero — an area called Columbia Heights, in Northwest D.C. But making an interactive map with a slider that showed the timing, we could see that it was moving into other areas of the city, especially in Southeast. We could also quickly see that the most affluent areas of the city had none of them.

Alexander von Humboldt pioneered the science now used to study climate change

AMID this year’s flurry of scientific jubilees, one seems to have passed largely unnoticed. On May 6th admirers celebrated the 150th anniversary of the death of Alexander von Humboldt, a Prussian naturalist and geographer. He may no longer be as famous as some of his contemporaries, yet Humboldt’s work sheds a clear light on the great challenges the world faces today from climate change.

Humboldt cut a remarkable figure. He traveled widely, making scientific notes of his many geographical, zoological and botanical discoveries, and formulating theories to explain the relationships he observed. Humboldt noticed, for example, that volcanoes form in chains and speculated that these might coincide with subterranean fissures, more than a century before plate tectonics became widely accepted. Broadly educated, cosmopolitan and a polyglot, he championed the study of how living things were related to their physical surroundings. Charles Darwin described him as “the greatest traveling scientist who ever lived” and later added, “I have always admired him; now I worship him.”

Bounding Boxes for World Countries (Berkeley GADM)

June 23rd, 2009

[Editor's note: Knowing the longitude-latitude (latLng) bounding box of a feature gives us a clue as to what map scale or zoom level is required to fit the feature into our display area and thus what base map scale set to draw from. While this image does not provide actual coordinates, it visually establishes what such bounding boxes look like (further refinements can be had with respect to crossing the 180° meridian, note New Zealand). ]

Here is a map of all countries and their bounding boxes (when using a lat/long “projection”), highlighting those countries that cross the international date line, and for which these bounding boxes make little sense (this map is provided for diversion only).
