The Facebook Primary

facebook-primary

FiveThirtyEight maps the Facebook likes of the U.S. presidential candidates: “If Facebook likes were votes, Bernie Sanders would be on pace to beat Hillary Clinton nationwide by a nearly 3-to-1 margin and Donald Trump to garner more support than Ted Cruz and Marco Rubio combined. Anything seems possible this year, but, still, be careful how you interpret these numbers: Facebook likes are not votes.” They ain’t kidding—Ben Carson?! [via]

Esri’s Solar System Atlas

solar-system-atlas

Esri’s Solar System Atlas collects maps of all the planets, dwarf planets, moons, asteroids and comets that have been visited by spacecraft in one location. (At least the ones with solid surfaces.) Now keep in mind that  maps of other objects in the solar system are generally spacecraft imagery stitched together into a mosaic and displayed on a map projection, and this is mostly what is presented here (plus some colourized topographic maps and a few geologic maps). Not many of the maps are labelled, which is a shame: bare imagery isn’t terribly useful. Also, the map tiles load slowly, and zooming out doesn’t always refresh them. But as a concept, I’m all for this. More from Esri’s Matt Artz. [via]

Georeferenced Historic Maps

The National Library of Scotland has an online map viewer that overlays georeferenced old maps atop a modern web map interface (Bing, I believe). Among my crowd, it’s the various 19th-century Ordnance Survey maps of London that generate the most excitement, though there are plenty of other locales (mostly but not exclusively in the U.K.) and time periods.

World Population Growth

The population of the world from 1 CE/AD through the end of the 21st century (projected) is mapped in this video and interactive map from Population Connection, a group concerned with the carrying capacity of the planet and the environmental impact of overpopulation (they used to be Zero Population Growth back in the day). In each, one dot represents one million people. [via]

Mapping Gentrification

boston-gentrification

Governing used interactive maps to measure the gentrification of the neighbourhoods of Boston (above) and 49 other cities as part of their report on gentrification in the United States last year. “While it has become much more prevalent, gentrification remains a phenomenon largely confined to select regions, not yet making its way into most urban areas. In the majority of cities reviewed, less than one-fifth of poorer, lower priced neighborhoods experienced gentrification. If all city neighborhoods are considered—including wealthier areas not eligible to gentrify—less than one of every ten tracts gentrified. Cities like Detroit, El Paso and Las Vegas experienced practically no gentrification at all.” [via]

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.
