Lake Poopó has become the Aral Sea of the Andes. Thanks to drought, water diversion and mining activity, the lake—long, wide, shallow, saline and the second-largest in Bolivia—has basically dried up, as this comparison of 2013 and 2016 Landsat 8 images demonstrates. CBC News, The Independent.
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 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 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.
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]
By cross-referencing public data on energy consumption with georeferenced tax lot data, Jill Hubley has created an interactive map of New York City’s greenhouse gas emissions by property, colour-coded to show the biggest emitters. More on how she did it, and what the data reveal. [via]
Andy Woodruff imagines Boston neighbourhoods as islands, where any unpopulated areas—commercial districts, industrial areas, highways, parks—are represented as water. “Some neighborhoods of the Boston area are actual islands, or were at one point. Others, however, can feel that way even when connected to each other by land. Water isn’t the only thing that can create a gulf between neighborhoods; sometimes it’s created by features of the urban landscape and the experience of passing through them.” [via]
Thanks to a surprising number of links about city maps waiting in the queue to be posted, today’s blog posts will have cities as their theme.
According to analyses by NASA and NOAA scientists, 2015 was the warmest year on record, with average surface temperatures the highest they’ve been since 1880. The above video shows the long-term warming trend since 1880 as a five-year rolling average. The baseline average is from 1951 to 1980; orange colours are warmer than that average, blue colours cooler. (Credit: GSFC Scientific Visualization Studio.)
The New York Times maps the rise in deaths from drug overdoses. “Some of the largest concentrations of overdose deaths were in Appalachia and the Southwest, according to new county-level estimates released by the Centers for Disease Control and Prevention. […] The death rate from drug overdoses is climbing at a much faster pace than other causes of death, jumping to an average of 15 per 100,000 in 2014 from nine per 100,000 in 2003.” [via]
Opening today at the Musée des civilisations de l’Europe et de la Méditerranée in Marseille, France, and running until May 2nd, Made in Algeria: Généalogie d’un territoire is an exhibition of nearly 200 “maps, drawings, paintings, photographs, films and historical documents as well as works by contemporary artists who surveyed the territory of Algeria.” The exhibition examines not only the cartography of the French colonial period, but the political and cultural narratives—to say nothing of the territory itself—created by colonial mapmaking. Lots of material on the exhibition’s website, but it’s French-only. [via]
