Sajjad Anwar and Sanjay Bhangar have been playing with train, station and schedule data from Indian Railways, one result of which (so far) is this reachability map—all the destinations reachable by a single train (i.e., without a transfer) from a given station. [Sajjad Anwar]

Google Maps’s new, cleaner look, which rolled out last month and replaces clusters of points of interest with coloured “areas of interest,” “represents the company’s ongoing efforts to transform Maps from a navigational tool to a commercial interface and offers the clearest proof yet that the geographic web—despite its aspirations to universality—is a deeply subjective entity,” writes Henry Grabar in Slate.
Rail Map Online is a web-based map showing every rail line that ever existed in the United Kingdom and Ireland. Base layers can be toggled between Google Maps, satellite, OpenStreetMap and old Ordnance Survey maps. It doesn’t distinguish between existing and removed rail lines, though that appears to be coming; it’s a work in progress. [Tim Dunn]

Google’s low- and medium-resolution satellite imagery has gotten a comprehensive update with new imagery from the Landsat 8 satellite. It’s the first such update to its seamless, cloud-free mosaic in three years. The Atlantic has detailed coverage (that helpfully points out, among other things, that this doesn’t apply to the highest zoom levels: those images come from DigitalGlobe satellites and aerial photography).
Moris Büsing’s interactive map chronicles the deaths of migrants and refugees trying to reach Europe over the past 15 years—more than 32,000 deaths in all. [Boing Boing]
Citing security concerns, India’s interior ministry has rejected Google’s plans to bring Street View to that country.
Satellite imagery from the Pléiades-1A satellite showing the extent of wildfire damage caused to Fort McMurray, Alberta can be viewed through a web-based mapping application released by the government of Alberta. (Doesn’t work in Safari for Mac; works fine in Chrome.) [CBC News]

In an essay called “What Happened to Google Maps?” Justin O’Beirne notes that between 2010 and 2016 Google Maps has changed from emphasizing cities at the expense of roads to emphasizing the road network at the expense of cities—a turn he chalks up to the shift to mobile device usage—and turns to a 1960s-era paper map to demonstrate what he thinks a balanced Google Maps should look like. An interesting look at the design choices in online maps. [Cartophilia]
This interactive map of the number of intercity rail trips between Ukrainian cities would be a little easier for me to parse if I could read Ukrainian, but I agree with Aleks Buczkowski’s assessment that it’s well designed. [Geoawesomeness]
Kenneth Field’s map of Mars (note updated link) now includes an option to add oceans, with checkboxes to fill the landscape to various elevations.
You can irrigate the planet below the areoid on this map using the water layers. You’ll notice the water layers aren’t blue. On Earth, water appears blue due to red, orange, yellow and green wavelengths of light being absorbed more strongly than blue and also the reflectence of the blue sky. Since Mars has relatively little atmosphere and it’s farther from the sun it’s likely water will appear differently. We’re imagining wavelengths will be absorbed differently, perhaps returning an alien green?

Le Télégramme, a French newspaper based in Brittany, maps the percentage of immigrants in France by canton; a second map shows the largest source of immigration (Portugal shows up more than any other country). In French. [Maps Mania]
In Smithsonian, Erin Blakemore explores the on-the-ground, amateur efforts to get disadvantaged communities—slums, shanty towns, whatever they may be called—on the map, like the Map Kibera and Mapillary projects, and the implications of such projects.
Sterling Quinn, who is earning his Ph.D. in geography at Penn State, notes that there are downsides to user-generated maps. Just because an underserved community makes its way onto the map doesn’t mean it becomes less vulnerable, says Sterling. “Putting yourself on the map may make you more vulnerable to people who want to exploit the area,” he tells Smithsonian.com.

Online maps showing the age of buildings in cities seem to be a thing. In addition to the map of Paris we saw in February, there’s also this map for Edmonton, Alberta. (Wired put together a list of other cities’ building age maps in 2013.) [via]
“Although Google Maps is fast becoming the ultimate authority on navigation,” writes Karen Turner for the Washington Post, “the program is proving vulnerable to mistakes and hackers with results that at times can be catastrophic.” Turner focuses on Google and problems with its error-correction and verification processes; it’s worth remembering, though, that all online maps suck in some way: no map service has a monopoly on accuracy or error.

Axis Maps’s Dave Heyman offers some advice on interactive map design—specifically, on the details, like colour usage and data interfaces. “Academic cartography provides good guidelines for thematic cartography, but interactivity and user-interface design are often ‘I know it when I see it’ type of things. What follows are 4 quick design concepts and techniques that can be applied in many situations to improve the look and feel of an interactive map.” [via]
