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...

Can’t find Iran on a map

Based on a Morning Consult/Politico survey, most people don’t know where Iran is: As tensions between the United States and Iran rise in the aftermath of the American drone strike that killed the country’s most powerful commander, Gen. Qassem Soleimani, a new Morning Consult/Politico survey finds fewer than 3 in 10 registered voters can identify the Islamic republic on an unlabeled map. The data is noisy, with selections in the...

Draw a ridgeline map showing elevation, for anywhere on Earth

Ridgeline charts or frequency trails use parallel lines that overlap on the fluctuations, which creates a 3-D effect at the peaks. Andrei Kashcha used this method to show elevation around the world in an interactive map. Click-and-drag to any location, and you get something like the above. You can also change parameters like maximum peaks, line density, and color. Even get your results printed on a mug. Kashcha posted his...

Urban growth via satellite imagery

For The Upshot, Emily Badger and Quoctrung Bui looked for major urban developments in the United States by comparing satellite imagery of past to present: To grasp the scale of this decade of change, The Upshot worked with Tim Wallace and Krishna Karra from Descartes Labs, a geospatial analytics company, using a tool that has itself evolved significantly over this time: satellite imagery. With its growing power and precision, we...

One leaked file, the location of 12 million smartphones

A file leaked to The New York Times contained location traces of 12 million unique smartphones. Stuart A. Thompson and Charlie Warzel went digging: The data set is large enough that it surely points to scandal and crime but our purpose wasn’t to dig up dirt. We wanted to document the risk of underregulated surveillance. Watching dots move across a map sometimes revealed hints of faltering marriages, evidence of drug...

Arctic ice melting

One way to gauge the amount of ice in the Arctic is to look at the average age of the ice. From the NASA Scientific Visualization Studio, the map above shows the estimated age of ice on a monthly basis, going back to 1984: One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. Perennial sea ice, also known as multi-year...

Where Christmas trees come from

For The Washington Post, Tim Meko and Lauren Tierney: Before the 1930s, Christmas trees typically were cut down on an individual’s property or out in the wild. Now, tree farms in all 50 states (yes, Hawaii too) are where most Christmas trees come from, accounting for 98 percent of live Christmas trees brought into homes. These farms churn out many kinds of conifers, but two main regions — Clackamas County...

Using old ship logs as a window into the weather in the 1800s

For Reuters, Feilding Cage describes a weather time machine project by NOAA that uses old shipping logs to build climate models for the 19th century: In the 19th and early 20th centuries, millions of weather observations were carefully made in the logbooks of ships sailing through largely uncharted waters. Written in pen and ink, the logs recorded barometric pressure, air temperature, ice conditions and other variables. Today, volunteers from a...
