• National Broadband Map shows how connected your community is

    February 17, 2011  |  Mapping

    Consumer broadband and population

    To encourage the integration of broadband and information technology into local economies, the National Telecommunications and Information Administration (with some help from Stamen) now provides an exploratory tool for broadband in your community:

    The National Broadband Map (NBM) is a searchable and interactive website that allows users to view broadband availability across every neighborhood in the United States. The NBM was created by the National Telecommunications and Information Administration (NTIA), in collaboration with the Federal Communications Commission (FCC), and in partnership with 50 states, five territories and the District of Columbia. The NBM is a project of NTIA's State Broadband Initiative. The NBM will be updated approximately every six months and was first published on February 17, 2011.

    There's a lot of data to look at, but you can search for the city or zipcode that you're interested in, and get information on what's available, as shown below. You can also see how your city compares to other locations in the country.

  • City traffic visualized as blood vessels

    February 14, 2011  |  Mapping

    Traffic hotspots

    Pedro Cruz puts a twist on the traditional map approach to visualize traffic in Lisbon as blood vessels:

    In this work the traffic of Lisbon is portrayed exploring metaphors of living organisms with circulatory problems. Rather than being an aesthetic essay or a set of decorative artifacts, my approach focuses on synthesizing and conveying meaning through data portrayal.

    Vessels swell and wiggle as traffic picks up during the rush hour and then relax and shrink as traffic goes down. More useful than an actual map? Probably not. Fun and engaging? Yes. Catch the short animation below.

    Surnames map

    Mina Liu and Oliver Uberti for National Geographic examine the most common surnames across the country:

    What's in a Surname? A new view of the United States based on the distribution of common last names shows centuries of history and echoes some of America's great immigration sagas. To compile this data, geographers at University College London used phone directories to find the predominant surnames in each state. Software then identified the probable provenances of the 181 names that emerged.

    The most common surnames are then placed geographically and colored by origin. Browse the full-sized map here. Is your name in there?

  • Map of scientific collaboration between researchers

    January 27, 2011  |  Mapping

    Science research collaboration

    In the spirit of the well-circulated Facebook friendship map by Paul Butler, research analyst Olivier Beauchesne at Science-Metrix examines scientific collaboration around the world from 2005 to 2009:

    I was very impressed by the friendship map made by Facebook intern, Paul Buffer [sp] and I realized that I had access to a similar dataset. Instead of a database of friendship data, I had access to a database of scientific collaboration.

    From an extensive database of academic citations:

    I extracted and aggregated scientific collaboration between cities all over the world. For example, if a UCLA researcher published a paper with a colleague at the University of Tokyo, this would create an instance of collaboration between Los Angeles and Tokyo.

    After that, Beauchesne used a similar mapping scheme that Butler used, and behold the results above. The brighter the lines, the more collaborations between a pair of universities.

  • Where people swear in the United States

    January 25, 2011  |  Mapping

    Twitter and swearing

    Cartographer Daniel Huffman has a look at swearing in the United States, according to geocoded tweets:

    Isolines are based upon an interpolated surface generated from approximately 1.5 million geocoded public posts on Twitter between March 9th and April 12th, 2010. These data represent only a sample of all posts made during that period. Isolines are based upon the average number of profanities found in the 500 nearest data points, in order to compensate for low population areas.

    The brighter the red, the more profanities used in the area, and the more black, the less swearing. Words looked for were (pardon my language): fuck, shit, bitch, hell, damn, and ass, and variants such as damnit. Honestly, I never swear like this. Unless some idiot pickup truck tailgates me going 80 on the highway in the middle of the night. That doesn't count though.

  • Map of North American English dialects and subdialects

    American English Dialects

    Rick Aschmann has made a hobby out of studying and mapping North American English dialects:

    This is just a little hobby of mine, that I thought might be interesting to a lot of people. Some people collect stamps. Others collect coins. I collect dialects.

    Aschmann goes on to explain the map:

    There are 8 major English dialect areas in North America, listed below the map at left. These are shown in blue, each with its number, on the map and in the Dialect Description Chart below, and are also outlined with blue lines on the map. The first 6 of these begin at the eastern seaboard and proceed west, reflecting western settlement patterns.

    There are even several hundred YouTube links clickable through the map that serve as subdialect samples. What dialect do you speak?


  • Old map shows slavery in the United States

    December 29, 2010  |  Mapping

    Chropleth map of Slavery in the US

    In 1864, drawing on the most recent 1860 Census data, the United States Coast Survey issued this choropleth map depicting counties with relatively high slave populations. President Lincoln was seen looking over the map so often that it was included in Francis Bicknell Carpenter's painting "President Lincoln Reading the Emancipation Proclamation to His Cabinet."

    Carpenter spent the first six months of 1864 in the White House preparing the portrait, and on more than one occasion found Lincoln poring over the map. Though the president had abundant maps at his disposal, only this one allowed him to focus on the Confederacy’s greatest asset: its labor system. After January 1, 1863—when the Emancipation Proclamation became law—the president could use the map to follow Union troops as they liberated slaves and destabilized the rebellion.

    How's that for a powerful map?

    You might think that the only use for a map is to find directions to where you want to go. Or since you're a FlowingData reader, you know they can be used for a bit more — like displaying large amounts of data. But if you think all they're used for, then you've got some learning to do my friend. Learn the steps from the all-knowing MacGyver in the video below.

    The best company you could have in a strange place is a map.

    Mapping America

    Government data technology has felt behind the times the past few years with outdated Java applets and such, which makes it tedious to look at all the data that is offerred. For example, if anyone understands the makeup of the United States, it's gotta be the people at the Census Bureau, but the tools for public access are rough around the edges.

    Luckily, we have the New York Times to move things along. Matthew Bloch, Shan Carter and Alan McLean apply their cartography skills to US Census data and let you explore a variety of demographics. It's like a demographic buffet. There are multiple maps across four topics: race and ethnicity, income, education, and housing and families.

  • Filling in the black holes of the Facebook friendship map

    Facebook filled

    While it was fun looking at the worldwide connections on Facebook, I thought it was more interesting to look at the places where there were very few connections, where it looked pretty dark on Paul Butler's map. Some commented that was just a product of no people in those areas. Where there's no people, there's obviously no Facebook. This is true in many areas, but not all them.

    United States Facebook connections

    As we all know, people all over the world use Facebook to stay connected with friends and family. You meet someone. You friend him or her on Facebook to keep in touch. These friendships began within universities, but today there are friendships that connect countries. Facebook engineering intern Paul Butler visualizes these connections:

    I defined weights for each pair of cities as a function of the Euclidean distance between them and the number of friends between them. Then I plotted lines between the pairs by weight, so that pairs of cities with the most friendships between them were drawn on top of the others. I used a color ramp from black to blue to white, with each line's color depending on its weight. I also transformed some of the lines to wrap around the image, rather than spanning more than halfway around the world.

    In other words, for each pair of countries with a friend in one country and a friend in the other, a line was drawn. The more friends and distance between two countries, the brighter the lines on a black-blue-white color scale. The "stronger" connections were drawn on top, so they are more visually prominent.

    It might remind you of Chris Harrison's maps that show interconnectedness via router configurations.
