A Snowstorm Revealed Through Traffic Delays

traffic

NPR graphics editor Alyson Hurt discovered that this month’s blizzard was showing up in Google Maps as traffic delays, and whipped up a little script that took regular screencaps of Google Maps’s traffic layer. She then created an animated GIF from the screencaps. The end result (above) dramatically shows the storm sweeping across the mid-Atlantic states.

Andy Woodruff then took Hurt’s script and created an animation of an ordinary day of Boston traffic. For a “quick, crude” script it certainly seems to have potential. [via]

Antiquity à la Carte

antiquity-alacarte

The Ancient World Mapping Center—formerly the Classical Atlas Project, the team behind the Barrington Atlas of the Greek and Roman World, the expensive atlas later reborn as an iPad app (iTunes link)—has a web-based map interface to classical/late antiquity geographic data. The original (2012) version of “Antiquity à la Carte” is kind of old school and clunky; the (2014) beta version shows a bit more promise. [via]

Online Map Updates

Yesterday’s updates to Apple Maps include four new Flyover cities, traffic data for Hong Kong and Mexico, public transit data for Los Angeles, and Nearby search for the Netherlands.

Google Earth Blog reports on the mid-January imagery update for Google Earth.

Google Earth Blog also reports that version 1.0 of ArcGIS Earth is now available. Announced last June and previously available as a series of public betas, ArcGIS Earth appears to be aimed at filling the gap left by Google when Google Earth Enterprise was discontinued last year.

Mont Blanc, the highest mountain in the Alps, is now in Street View.

Le Grand Paris en Cartes

grand-paris

Le Grand Paris en Cartes is a collection of interactive maps and infographics about the Grand Paris Express, a multi-billion-euro project to extend Paris’s Metro and rapid transit network deep into the surrounding Île-de-France region (if you can read French, the official site and French Wikipedia page provide a lot more information). These maps not only illustrate Parisians’ commuting routes and Metro usage, but also (see above) the kind of sociological data that underpins transit planning: employment centres, population density and so forth. In French. [via]

Cities and Memory

Cities and Memory is an exercise in sound mapping: a map of ambient sounds from hundreds of locations. Stuart Fowkes writes, “Every location and every faithful field recording on the sound map is accompanied by a reworking, a processing or an interpretation that imagines that place and time as somewhere else, somewhere new. The listener can choose to explore locations through their actual sounds, or explore interpretations of what those places could be—or to flip between the two different sound worlds at leisure.” It’s open to submissions.

Urban Scratchoff

Using an interactive interface to compare present-day and historical maps and aerial imagery is done all the time—on this website I use a slider plugin—but Chris Whong’s Urban Scratchoff uses a familiar metaphor to compare present-day aerial images of New York City with imagery from 1924. Give it a try. More on how Chris did it. [via]

Beware of Fake Snowfall Maps

Meterologist Dan Satterfield warns about fake snowfall maps appearing on social media. “[R]esponsible meteorologists do not post raw model data more than 3 days away from an event. It’s just not likely to be correct, and could actually give someone a false sense that the storm will not impact them. […] If you see a map showing snowfall totals, it almost certainly did not come from NOAA, or an AMS Certified meteorologist. There are even hoax maps floating around from storms in the past” (emphasis his).

Google Maps Updates

Recent Google Maps updates include driving mode, an Android-only navigation mode that, as Android Police describes it, “uses your location history and web searches to make assumptions about where you’re going and give traffic updates and ETAs as you travel” [via]. Also this week, the world’s largest model railway, Hamburg’s Minatur Wunderland, was added to Street View. Quite engrossing if you’re into model trains.

Mapping the Refugee Crisis

lucify-refugees

Here are two interactive maps that show the scale of recent refugee migrations. Lucify’s interactive map (screenshot above) shows the flow of asylum seekers to European countries since 2012. And this interactive map, compiled by The Conversation from UNHCR data, shows the size of refugee populations originating from or residing within each country from 1975 to 2010. In each case, the numbers grow with each passing year. More from Scientific American’s SA Visual blog. [via]
