• United States Poverty Rates From 1980 to 2007

    October 15, 2008  |  Mapping, Projects

    Thousands of bloggers are taking the time to discuss a single topic today - poverty. As we sit in our cozy homes, go out to eat, watch movies, or simply read the news on a computer, it's easy to forget that there are millions of people around the world who aren't so well off. Blog Action Day is an opportunity to remember and to perhaps help out in some way.

    Mapping Poverty Rates

    I of course took the visualization route. What better way to get the facts than through data? The US Census Bureau provides lots of poverty estimates, so I took their data and mapped it over the last 27 years. I found it alarming to see that some states had a poverty rate over 20%. I clearly live in a cozy bubble. What does your state look like?

  • Commercial Air Traffic Seen Around the World

    October 8, 2008  |  Mapping

    Commercial air traffic

    This computer simulation (video below) by Zhaw shows worldwide commercial flights over a 24-hour period. It's been making the blog rounds lately. Watch as flights start in the morning in the western hemisphere, and as the sun starts to come up in the east, more flights begin in the east. I'm not sure if we're seeing actual GPS traces or just interpolated flight paths from point-to-point data, but my guess is the latter. Does anyone understand the language on Zhaw?

  • Maps for Advocacy – Beginner’s Guide to Mapping

    October 2, 2008  |  Mapping

    In a follow up to Visualizing Information for Advocacy, the Tactical Technology Collective recently announced Maps for Advocacy: An Introduction to Geographical Mapping Techniques.

    The booklet is an effective guide to using maps in advocacy. The mapping process for advocacy is explained vividly through case studies, descriptions of procedures and methods, a review of data sources as well as a glossary of mapping terminology. Scattered through the booklet are links to websites which afford a glance at a few prolific mapping efforts.

    While the example maps look very Googley and won't impress too many in the online mapping world, there are still some good links in there for data resources, terminology, and how maps play a role in displaying information.

  • We Don’t Know Jack About the World – Alisa Miller TED Talk

    October 1, 2008  |  Mapping

    Alisa Miller, President and CEO of Public Radio International, enlightens us on how little U.S. news coverage there is on the rest of the world. How does she do this? She uses maps of course. Miller uses visualization to tell a (short) story. She shows us all the coverage on Iraq and the lack of coverage on all other countries, which is practically nothing.

    The name of this type of morphed map escapes me right now. Maybe someone can remind me?

    [Thanks, Jodi]

  • OneGeology Wants to Be Geological Equivalent of Google Maps

    September 11, 2008  |  Data Sources, Mapping

    There's lots of free geographical data about what's going on at the surface of our planet. It's a different story for what going on underneath though. OneGeology aims to be the solution to that problem.

    OneGeology is an international initiative of the geological surveys of the world and a flagship project of the 'International Year of Planet Earth'. Its aim is to create dynamic geological map data of the world available via the web. This will create a focus for accessing geological information for everyone.

    I've never been one for the geology, but if the data (and interactive maps) were easily accessible, there certainly would be a peak in interest.

  • See the World Through SimCity’s Eyes – One Up On OnionMap

    September 10, 2008  |  Mapping, Online Applications

    Michael comments, "Onionmap is nothing when compared to this Chinese site...They've practically mapped out the entire Shanghai (and quite a few other China cities) in a SimCity-like fashion! Amazing stuff!" He's completely right. Edushi maps Shanghai with great detail. While OnionMap looks like Google Maps with SimCity sprinkles, Edushi is just straight up SimCity.

    Unfortunately my three years of Chinese classes in high school did me no good, and I don't understand a thing on the site. Maybe someone can translate and let us know what Edushi is all about. Chinese CitySearch?

    [Thanks, Michael]

  • How to Create a Real-Time Web Traffic Map for Your Site

    September 3, 2008  |  Mapping, Projects

    I was exchanging email with Rob a few days ago, and he brought up that I might see a slight boost in traffic from Australia because he had spread the word (thanks!) at a statistics conference. I immediately went over to Google Analytics, and indeed, there was an increase in traffic from the land down under.

  • Tracking Hurricane Gustav – How Hard is it Going to Hit?

    August 31, 2008  |  Mapping

    Stamen has taken a step towards the concrete with their recent Hurricane Tracker for MSNBC. From what I can tell, it updates every couple of hours or so. The tracker shows where Hurricane Gustav has been and where it's headed and provides information on wind speed, ground speed, and location.

    From the map we see a development from tropical depression in the Caribbean Sea, to a big category 4 over Pinar Del Rio, and then something between a category 3 and 2 as it moves over New Orleans. Gustav dwindles to a tropical storm as it moves towards Dallas. With mandatory evacuations of New Orleans starting yesterday, here's to hoping everyone finds somewhere safe to stay.

  • History’s Greatest Journeys – Wanderlust from GOOD

    August 25, 2008  |  Mapping

    GOOD Magazine, in collaboration with Graham Roberts, maps the most famous journeys in history - some fiction, some non-fiction. Wanderlust includes trips like Around the World in 80 Days and Journey to the Center of the Earth to the voyages of Marco Polo and Charles Lindbergh's transatlantic flight. However, it's not just a map with journey lines on it; Wanderlust is a history lesson. Select a trip for a summary and explore highlights of the journey.

  • Britain From Above – Beautiful Use of Satellite Technology

    August 11, 2008  |  Mapping

    The BBC has a gorgeous documentary series that started yesterday -- Britain from Above. They take a look at Britain from the skies using satellite technology and GPS data. Watch patterns emerge as taxis, ships, and planes travel back and forth and information and data pass through Britain's national telephone network. The imagery is beautiful. I love visualization that brings data to life.

    The high-resolution videos don't seem to be working right now, but here's just a small sample:

  • It’s Like Google Maps with Sim City 2000 – OnionMap

    August 7, 2008  |  Mapping

    Remember SimCity 2000? That was a great game. That was probably the last computer game I played for any significant length of time, and if my Macbook Pro were able to read 5-inch floppies, I'd totally pop it in and build myself a city called Yau Town.

    Put the look of SimCity 2000 together with Google Maps, and you get OnionMap. Most of the site is in Korean, but from what I gather it aims to be something of a tourist guide with a little bit of social network mixed in. That part of OnionMap is a little fuzzy, but it was worth the five minutes for the maps.

  • Watching Our Twitter World – twittervision Redux

    July 28, 2008  |  Mapping, Projects, Software

    I've always liked twittervision. I'm not sure what it is, but it's strangely mesmerizing, getting a tiny peak into others' lives. This weekend, I recreated twittervision with a little bit of style for good measure. Say hello to Twitter World.

    The Data

    Twitter World shows updates from the Twitter public timeline, and makes use of the twittervision API for location. Until I get whitelisted for the Twitter API, I'm polling Twitter and twittervision every six minutes to keep things fresh. Hopefully neither putters out.

    The Implementation

    Like my visualization showing the spread of Walmart, I used Modest Maps (+ OpenStreetMap) to map things out, and I used TweenFilterLite to animate. I had all the gears in place and everything working nicely a couple of hours in - but that was with a flat XML file. The hard part was feeding the thing live data and then making sure everything was synchronized. That took, um, too much time.

    In any case, not bad for a weekend project.

    PS. Don't forget to follow me on Twitter :)

  • Mapping Walkability in San Francisco

    July 24, 2008  |  Mapping

    Lee Byron, recent Carnegie Mellon grad and newly inducted New York Times graphics intern, maps walkability in San Francisco. He scraped Walk Score for uh, walk scores, which are scores from 0-100 based on the amenities around a location like "nearby stores, restaurants, schools, parks, etc" - how easy it is to live without a car.

    Color was calculated on a per pixel basis using bicubic interpolation. From there he let Processing do the graphical labor to construct a map overlay. The result, which is accurate to the block, is a pretty one.

    If you want data (sans map) for your own neighborhood, Lee has kindly provided the scraper.

  • Mapping Economic Activity for the World

    July 14, 2008  |  Economics, Mapping

    The G-Econ (Geographically-based Economic data) group has worked on making economic data publicly available via Gross Cell Product (GCP). In other words, they've collected data for each 1x1 degree latitude by longitude cell on the globe. Above is a cell-by-cell globe mapping world population. Here's one that shows world rainfall.

    Check out more of these pretty world maps posted to the G-Econ Flickr photo set.

  • Map With All the Common APIs at Once – Mapstraction

    July 8, 2008  |  Mapping, Software

    For those who want more out of the commonly-used mapping APIs from Google, Yahoo, Microsoft, etc, but don't want to get too heavy on the programming, Mapstraction is for you. Mapstraction is a javascript mapping abstraction library that lets you easily use different mapping APIs all at once (or switch between them).

    This means you can use functionality from one API and apply it to another, or you can just put a whole bunch of synced maps on one page like above. Other features include geocoding, polylines, marker filters, and GeoRSS and KML, so go for it. Go map crazy.

  • How Much Does Gas Cost Where You Live?

    June 13, 2008  |  Mapping

    With gas prices going crazy high lately, here's this weekend's question:

    How much and where from did you pay for your latest gallon of gas?

    I just paid $4.11 for my last gallon and live in Buffalo, New York. That was a +$40 tank fill up - for a Honda Civic. Blech.

    P.S. Happy early Father's Day to all you dads out there!

  • Find Your Dream Home (or Fantasize) With Trulia Snapshot

    May 29, 2008  |  Mapping

    Trulia, the real estate search site, launched Trulia Snapshot today in collaboration with Stamen Design. It's a pretty mapping interface that lets you view pictures of properties on a map in a very interactive way i.e. it's fun to use and super fluid.

    First, you type a location you want to find properties at.

    First page

    From there you can browse properties by newest/oldest or most/least expensive with the map or with the histogram at the bottom.

    Full UI

    Select Property

    If you just want to sit back and watch, press play and the real estate properties will highlight automatically by the order you've selected, and the map will move back and forth by location. See something you like? Press pause. If not, just let the animations keep running - your own personal real estate agent.

    My favorite part of the visualization is how the bottom images blur as you whiz by. It's a very small part and not the focal point, but it's one of those little design things that make it that much better. Nice touch.

    Ultimately, success of such work is measured by (although it shouldn't need be) whether or not users would rather browse data with the visualization or with the usual listing pages. Give it a try - what would you rather use?

  • Measuring Informational Distance Between Cities

    May 22, 2008  |  Mapping

    Bestiario, the group behind 6pli, recently put up their piece that maps informational distance between cities. At the base is a freely rotating globe. Arcs, whose strength and height represent strength of relationship, connect cities. The metric to determine strength of relationship takes several contexts into account - Google searches for individual cities, cities together, and geographical proximity. Bestiario implemented the piece in actionscript and used their own 3d framework (in Spanish).

  • All 26 Million Road Segments in Continental United States

    April 28, 2008  |  Mapping

    road-map

    Ben Fry maps every road segment in All Streets, according to the U.S. Census Bureau's TIGER/Line data. There's no actual map or drawn borders; instead Ben chooses to let the data do all the work, and the results are very pretty. Sometimes you don't need a map to map.

    I was somewhat surprised to see California's low road density compared to the eastern half of the country, but I guess that's because of all the freeways. What's more surprising though is that line down the middle. Roads all of a sudden go dense somewhere around North Dakota. Is that really what it's like? Does farming suddenly stop and urban life begins in these areas?

    Poor Alaska and Hawaii, with too few roads, were left out.

  • Rolling Out Your Own Online Maps and Graphs with HTML/CSS

    April 24, 2008  |  Mapping, Statistical Visualization

    Wilson Miner and Paul Smith, two co-founders of Everyblock, post tutorials and a little bit of their own experiences rolling out their own maps and creating graphs with web standards.

    Why Not Go With Google Maps?

    Paul gets into the mechanics of how you can use your own maps discussing the map stack - browser UI, tile cache, map server, and finally, the data. My favorite part though was his reasons for going with their own maps:

    Ask yourself this question: why would you, as a website developer who controls all aspects of your site, from typography to layout, to color palette to photography, to UI functionality, allow a big, alien blob to be plopped down in the middle of your otherwise meticulously designed application? Think about it. You accept whatever colors, fonts, and map layers Google chooses for their map tiles. Sure, you try to rein it back in with custom markers and overlays, but at the root, the core component—the map itself—is out of your hands.

    Because it's so easy to put in Google Maps instead of make your own (although it is getting a little easier), everything starts to look and feel the same and we get stuck in this Google Maps-confined interaction funk. Don't get me wrong. Google Maps does have its uses and it is a great application. I look up directions with it all the time, but we should also keep in mind that there's more to mapping than bubble markers all in the color of the Google flag.

    Remember: a little bit of design goes a long way.

    Data Visualization with Web Standards

    Wilson provides a tutorial for horizontal bar charts and sparklines with nothing but HTML and CSS. Why would you want to do this when you could use some fancy graphing API? Using Everyblock as an example, data visualization can serve as part of a navigation system as opposed to a standalone graphic:

    Everyblock Graphs

    Sometimes the visualization isn't at the center of attention.

    Make sure you check out Everyblock, a site that is all about the data in your very own neighborhood, to see these maps and graphs in action.

    [Thanks, Jodi]
