Maps show spring arriving earlier

From Joshua Stevens at the NASA Earth Observatory: But over the longer term, climate change is causing spring to begin earlier and earlier across the United States. These maps reveal just how much earlier spring is arriving in National Parks across the country. The data were published in 2016 by ecologists from the National Park Service, working in collaboration with colleagues at other agencies and institutions. Griddy. Limited to only...

The Moon in 4k resolution

Based on data gathered by the Lunar Reconnaissance Orbiter, NASA pieced together this high-resolution tour of the moon. At the two-minute mark they zoom in on a boulder in the middle of a 100-million-year-old crater, and it blew my mind. Tags: high resolution, moon, NASA, space

SimCity-like views using satellite imagery

Maps typically show a view from straight above, which is good for navigation and to see regional patterns over large areas. However, missing out on the extra dimension of height can mean missing out on context. Robert Simmon for Planet Labs shows off some work in getting the less abstract perspective at a large scale.

Average first leaf appearance, as animated map

The USA National Phenology Network uses a computer model to estimate heat build-up and the “first leaf” appearance across the country. Jeremy White for The New York Times animated it. Tags: New York Times, weather

Traveling birds on a thousand-mile journey

Birds migrate to areas more hospitable, but where do they go? It depends on the bird. It depends on the time of year. It depends on other various factors. Drawing from several data sources, National Geographic maps how birds migrate thousands of miles. View it on your desktop of maximum animated pleasure. Tags: birds, migration

Fantasy map generator

This is fun. It’s a fantasy map generator with the following rules: Project goal is a procedurally generated map for my Medieval Dynasty simulator. Map should be interactive, scalable, fast and plausible. There should be enought space to place at least 500 manors within 7 regions. The imagined area is about 200.000 km2. Just click and there’s a new map generated on the fly. Martin O’Leary’s generator is still my...

Redistricting the congressional map with different goals

FiveThirtyEight asks, “There’s a lot of complaining about gerrymandering, but what should districts look like?” Looking for an answer, they imagined redistricting with different goals in mind, such as gerrymandering favoring Republicans or Democrats, promoting competitive elections, and maximizing majority-minority. Check out the possibilities for the nation or zoom in to a specific state. The latter provides a further breakdown by district and then race. So yeah, if you’re into...

Mapping global accessibility to cities

From The Malaria Atlas Project, a global map of estimated accessibility to cities: In the present study, we quantify and validate global accessibility to high-density urban centres at a resolution of 1×1 kilometre for 2015, as measured by travel time. The last global mapping effort to measure accessibility was for the year 2000, a time that predates both substantial investment and expansion of transportation infrastructure and an extraordinary improvement in...

Scale comparison of wildfires

The past few days in California has been non-stop rain, but the months before that, there was unprecedented wildfires in the state. Lauren Tierney, reporting for The Washington Post, provides an overview along with a scale comparison of 2017’s biggest fire against anywhere on the globe.

Mapping perceived canopy tree cover in major cities

Treepedia, from the MIT Senseable City Lab, estimates perceived tree cover at the street level. They used panorama views from Google Street View to form a “Green View Index”, which they then mapped for major cities. Treepedia measures the canopy cover in cities. Rather than count the individual number of trees, we’ve developed a scaleable and universally applicable method by analyzing the amount of green perceived while walking down the...
