The Bruce Murray Laboratory for Planetary Visualization has completed a 5.7 terapixel mosaic of the surface of Mars rendered at 5.0 m/px. Each pixel in the mosaic is about the size of a typical parking space, providing unprecedented resolution of the martian surface at the global scale.

This is so cool.

Neat - draw all the roads of any city and then you can order a mug. Pretty looking.

Very cool map visualization shows the most photographed places in the world.

Wow, what a cool website. First time I hear of it.
