This is the promise of big data, and it's really cool looking.
Nelson Minar, an engineer working at Google, created
this vector tile map of all the rivers in the U.S., based on a data from
NHDPlus, a suite of application-ready geospatial data sets supported by the EPA.
Minar worked on the project for a few weeks, to experiment with vector maps,
he wrote on his blog. But the finished product is so visually stunning it's been circulating the blogosphere.
The data is all available on the open source platform
GitHub, so you can make your own rivers map.
