Animated maps of seasonal Earth

As you might expect, NASA collects a lot of data, and much of it is seasonal. Eleanor Lutz animated a few maps to show the detail: To show a few examples, the NASA Earth Observations website includes data on seasonal fire incidence (1), vegetation (2), solar insolation, or the amount of sunlight (3), cloud fraction (4), ice sheet coverage (5), and processed satellite images (6). My own map (7) combines...

Home zoning in major cities

The single-family home. It’s part of the American dream, but it can be awfully expensive when land grows scarce. Emily Badger and Quoctrung Bui for The Upshot map and discuss the current approaches of major cities: A reckoning with single-family zoning is necessary, they say, amid mounting crises over housing affordability, racial inequality and climate change. But take these laws away, many homeowners fear, and their property values and quality...

The role of cartography in early global explorations

For Lapham’s Quarterly, Elizabeth Della Zazzera turns back the clock to maps used for navigation, starting with the 1300s and through 1720: From the fifteenth to the eighteenth century, European powers sent voyagers to lands farther and farther away from the continent in an expansionist period we now call the Age of Exploration. These journeys were propelled by religious fervor and fierce colonial sentiment—and an overall desire for new trade...

Map of the most popular people replacing the cities they lived in

For The Pudding, Matt Daniels and Russell Goldenberg used Wikipedia pageviews to replace city names with each city’s most popular resident: Person/city associations were based on the thousands of “People from X city” pages on Wikipedia. The top person from each city was determined by using median pageviews (with a minimum of 1 year of traffic). We chose to include multiple occurrences for a single person because there is both...

New abortion restrictions by state, since 2011

For FiveThirtyEight, Amelia Thomson-DeVeaux and Gus Wezerek categorized and mapped new abortion restrictions enacted by state legislatures from 2011 to 2019: The result is a complicated patchwork of abortion laws that have made it more time-consuming and expensive to get the procedure in certain parts of the country. In addition to counseling, waiting period and ultrasound requirements — all of which can increase the time and cost associated with the...

Mapping politically polarized cities

Rachael Dottle, for FiveThirtyEight, looked for political differences in cities and ranked them, based on precinct voting margins for the 2016 election: To see just how politically segregated America’s urban areas are, we used each city’s 2016 election results to calculate its dissimilarity index — basically, a number that tells us how separated its Republicans and Democrats are from one another, with higher numbers indicating more segregation. This technique is...

Inverted world map

Frans Block wondered what the world would look like if water and land were flipped. The deepest spots in the ocean become the highest mountains and the highest mountains become the deepest part of the sea: It is an extraordinary planet, this inverted world. It has more than twice as much land available as our own Earth. Which does not mean, however, that twice as many people can live there,...

Maps of natural disasters and extreme weather

For The Washington Post, Tim Meko mapped floods, tornados, hurricanes, extreme temperatures, wildfires, and lightning: Data collection for these events has never been more consistent. Mapping the trends in recent years gives us an idea of where disasters have the tendency to strike. In 2018, it is estimated that natural disasters cost the nation almost $100 billion and took nearly 250 lives. It turns out there is nowhere in the...

Where the IRS most likely audits

Using estimates from a study on regional bias in tax audits, ProPublica mapped the likelihood of getting audited by the IRS. They then turn their attention to Humphreys County, Mississippi: In a baffling twist of logic, the intense IRS focus on Humphreys County is actually because so many of its taxpayers are poor. More than half of the county’s taxpayers claim the earned income tax credit, a program designed to...

Mapping the cheapest flights to everywhere, given your location

Sometimes you really do need to get away. Escape, part search engine and part research project from students at the MIT Senseable City Laboratory in Singapore, shows you the cheapest flights out of any given city. Just put in a location, and you get color-coded connections to everywhere around the world. Tags: flights, prices
