Incredible interactive map that reveals every river in America

At first glance it looks like a blur of colour, but the incredible image actually shows all 250,000 rivers running through America.

Not only that, it also reveals which direction they run in, reports the Daily Mail.

Researchers have created the incredible maps from data created by the US Geological Survey.

It was created by Brooklyn designer Andrew Hill of data-visualisation firm Vizzuality.

He used theCartoDB platform and the National Hydrography Dataset, which is made available online by the US Geological Survey, to create the map.

“There are 18 distinct colors around the compass,” says Hill, who also works for CartoDB.

Pink, for example, represents a river that runs north-south or south-north.

CartoDB is a a cloud based mapping, analysis and visualization engine that lets users build spatial applications for both mobile and the web, and it often used on property websites and new sites to create maps.

Recently, the firm made its technology available for free.

“We realized that charging for map views was actually penalizing you for creating interesting maps,” said Hill.

'We no longer want you to have to worry about unexpected traffic or what happens when the maps on your account go viral.

The longest river on the map is the Missouri at 4088 kilometres, although the biggest in terms of water volume is the Mississippi, which is deeper.

At 1114 kilometres, the Yellowstone is the longest un-dammed river in the US.
