Judging connectedness of American communities, based on Facebook friendships

We talk about geographic bubbles a lot these days. Some areas are isolated, in their own bubble. Other areas seem more connected. Emily Badger and Quoctrung Bui for The Upshot looked at this geographic connectedness through the lens of Facebook friendships. In the millions of ties on Facebook that connect relatives, co-workers, classmates and friends, Americans are far more likely to know people nearby than in distant communities that share...

Watch rising river levels after Hurricane Florence

Hurricane Florence brought a lot of rain, which in turn made river levels rise. The New York Times animated the rise over a five-day period. The height of the bars represents the rise of the river level, as compared to levels on Thursday. I like the visual metaphor of bars going up with river levels. I’m not sure the sudden rise and falls in such short periods of time would...

3-D view inside Typhoon Mangkhut

Typhoon Mangkhut went through the northern end of the Phillipines a few days ago. At least 25 people died. The New York Times provides a scrolling 3-dimensional view using data collected by NASA satellites. Tags: 3-d, New York Times, typhoon, weather

Hurricane Florence trackers

Hurricane Florence is forecast to touch down Thursday night or Friday, and what’s become the norm, there are several ways to see where the hurricane is and where it might go. Here are a handful of views. Each focuses on different aspects of potential storm.   The Washington Post shows the five-day chance of tropical-storm-force winds instead of the possible path of the hurricane. As noted by Gregor Aisch, this...

Night lights mapped as terrain

You’ve probably seen the maps of Earth at night. It gives you a good idea of activity around the world, through the eyes of light. As an experiment and a shift in view, Jacob Wasilkowski mapped the light as terrain. Tags: light, terrain

World map shows aerosol billowing in the wind

Using a mathematical model based on satellite data, NASA shows an estimate of aerosol in the atmosphere on August 23, 2018: The visualization above highlights GEOS FP model output for aerosols on August 23, 2018. On that day, huge plumes of smoke drifted over North America and Africa, three different tropical cyclones churned in the Pacific Ocean, and large clouds of dust blew over deserts in Africa and Asia. The...

World Cup play activity visualized like wind maps

A fun experiment by Neil Charles that used the aesthetics of wind maps to represent World Cup 2018 play activity: It looks like the familiar shape of an average football game, with the bulk of the play happening out wide and then converging onto the opponent’s area. Colour in this is example is by number of passes (hotter = more) and I’ve also drawn locations with fewer passes more faintly,...

Scale of the California wildfires

The Mendocino Complex Fire, now the largest in California ever, continues to burn. I live a couple of hundred miles away, but the sky is yellow and orange at times, and it was smokey a few days ago. It’s a bit crazy. Lazaro Gamio for Axios provides a quick view to show scale with an animated graphic compared against Washington, D.C. and Manhattan. Tags: Axios, California, fire, scale

A transforming river seen from above

The Padma River in Bangladesh is constantly shifting its 75-mile path. Joshua Stevens for the NASA Earth Observatory shows what the shifting looked like through satellite imagery, over a 30-year span. Kasha Patel: The upper section of the Padma—the Harirampur region— has experienced the most erosion and shows the most notable changes. The river has become wider at this section by eroding along both banks, although most activity occurred on...

How America uses its land

Dave Merrill and Lauren Leatherby for Bloomberg visualized land use for the conterminous United States using a pixel-like grid map: The 48 contiguous states alone are a 1.9 billion-acre jigsaw puzzle of cities, farms, forests and pastures that Americans use to feed themselves, power their economy and extract value for business and pleasure. Using surveys, satellite images and categorizations from various government agencies, the U.S. Department of Agriculture divides the...
