NASA has created the largest high resolution mosaic of the Moon’s north polar region using images taken by the Lunar Reconnaissance Orbit. The 2-meter-per-pixel images cover an area equal to more than one-quarter of the United States.
A large version of the map has been posted at http://lroc.sese.asu.edu/gigapan. At that site you can zoom in and out, and pan around an area. The map mosaic was constructed from 10,581 pictures and provides enough detail to see textures and subtle shading of the lunar terrain. Consistent lighting throughout the images makes it easy to compare different regions.
