If you didn't think people were obsessed with sharing on the internet before, we dare you to feel the same after viewing these maps.
Flickr user Eric Fischer compiled the images below by taking geo-location data from Flickr photos and Twitter and plotting those coordinates on a map. The result is an astounding skeletal structure of some of the world's biggest cities.
But he didn't stop there. Fischer went on to specifically map all of Europe and North America, as well as the entire world. The North American image itself took almost 45 minutes to compile, according to the Daily Mail.
There's not a whole lot of technology behind it. It's a C program that runs through the photos/tweets in chronological order, plotting the earliest ones the most brightly and stepping the brightness down for points that don't show up for the first time until later on.
Points are also allowed to diffuse by a few pixels when there is an additional record for a point that is already plotted, with the brightness falling off exponentially as the point that is actually plotted gets further from its intended location. Each pixel is the somewhat weird area of 2.25 square miles because a smaller area made the whole-world image too big for Flickr to let me post it.
In the maps below, red dots represent where pictures shared on Flickr were taken, blue dots represent tweets, and white dots represent areas with both types of sharing.
