Particle flows show how the coronavirus ramped up

Using a combination of estimates based on cell phone movements and outbreak size, The New York Times shows how the coronavirus started with a few cases and then spread around the world. The particle flows to represent travel volume from city to city is something else. NYT used a scrollytelling format that starts on a geographic map. You see a few points at first, the virus spreads, and then there’s...

Deer crossing across highway corridors

With the climate changing, animals will need to migrate to different areas to live, but that can be a challenge when there is a giant highway blocking the way. The Washington Post looks at how scientists in Wyoming are hoping to clear the path: “We can’t predict exactly what the impacts of climate change are going to be, or what species are going to be impacted,” said Hall Sawyer, a...

Hospital bed occupancy

Using estimates from the Harvard Global Health Institute, The Upshot mapped what hospital bed occupancy might look like across the country if we don’t make changes now: “If we don’t make substantial changes, both in spreading the disease over time and expanding capacity, we’re going to run out of hospital beds,” said Dr. Ashish Jha, the director of the Harvard Global Health Institute, which produced the estimates. “And in that...

Map shows how NASA satellites collect global rain data

We can download data as a single snapshot in a single file, but oftentimes that data is generated piece-by-piece. In the map above, NASA shows how they piece together rain data with a network of satellites: The ten currently-flying satellites in the Global Precipitation Measurement Constellation provide unprecedented information about the rain and snow across the entire Earth. This visualization shows the constellation in action, taking precipitation measurements underneath the...

Forgotten map types

Geographer Tim Wallace likes to look at old maps, and is particularly fond of the weird and forgotten types: So, I slowly amassed a more complete list. And here it is. Most of these map types are silly or unusual, not forgotten. Many of them are even deliberately taken out of context to highlight their wackiness and how easily maps can be misread (I sure misread them all the time!)....

Mapping the construction of railroads in America

For the Financial Times, Alan Smith and Steven Bernard traced the history of railroad construction in America and mapped it over time. Literally. Bernard used digitized versions of old maps and traced each new segment by hand. Tedious, but the result is impressive. Tags: animation, Financial Times, railroad

Geography of FM radio

So get this. There are these things called radio stations that broadcast music using frequency modulation. They call it “FM radio.” You don’t download or stream the music, and you don’t get to choose what songs you want to hear right away, but sometimes you can call locally and request a song you like. It’s also free to listen to if you have this thing called a “radio.” In exchange,...

Make a streets map of anywhere in the world

Following up on his mini-app to draw ridgeline maps for elevation, Andrei Kashcha made a tool to draw a streets map of anywhere in the world. Enter a city, and using data from OpenStreetMap, you’ve got yourself a map for export. You can also easily change the color scheme to your liking, which is fun to play with as you scroll back and forth. Finally, Kashcha also put the code...
