“Where people post geotagged photos to Flickr from and geotagged tweets to Twitter from.” via Eric Fischer

Red dots are locations of Flickr pictures. Blue dots are locations of Twitter tweets. White dots are locations that have been posted to both.

We Are Here Now / Spatial Information Design Lab / Columbia University | visual data | Scoop.it

Always checking your favorite sites for updates, or checking in with Facebook or Foursquare? You’re not alone and Columbia’s Spatial Information Design Lab can prove it. In addition to sharing your whereabouts, your geographic mark provides insight in examining the psycho-geography and economic terrain of the city.

For their social media study, the Lab used the Foursquare and Facebook Application Programming Interfaces (API’s) access location-based data to determine where social media users broadcast that they are “Here Now”, and have transformed that data into a graphic language that provides a sense of how the city is organized with regards to how people travel around the city, where there are employment and commercial centers, and seasonal preferences...

How Big Data Can Boost Weather Forecasting

How Big Data Can Boost Weather Forecasting | visual data | Scoop.it

Increasing evidence of climate change worldwide is prompting governments and scientists to take action to protect people and property from its effects. But, to take effective action, they need to know understand a lot more about the weather–everything from what’s going to happen tomorrow to what’s coming next year.


IBM scientists are taking the lead in bringing the most sophisticated data analytics to bear on weather forecasting. They established at test bed in the New York City area, where they set up a three-dimensional grid of thousands of blocks. That makes it possible to run calculations that produce very precise weather forecasts for a particular locale. Using this capability, the team predicted with remarkable accuracy the snowfall totals in New York City during the snow storm that blanked the northeastern United States in February–and also to predict accurately when the snowfall would start and stop.

The Research team is putting their algorithms to work on behalf of cities around the world. For instance, Rio de Janeiro has recurring flooding and landslide problems in many hilly neighborhoods, so the researchers used data to create a mathematical model of how storms are likely to unfold in Rio. With it, they can predict up to 40 hours ahead of time how much rain will fall in a particular location—with 90% accuracy.
