LROC Northern Polar Mosaic

The Lunar Reconnaissance Orbiter Camera (LROC) team assembled 10,581 Narrow Camera Angle images, collected over four years, into a spectacular northern polar mosaic. The LROC Northern Polar Mosaic  (LNPM) is likely one of the world’s largest image mosaics in existence, or at least publicly available on the web, with over 680 gigapixels of valid image data covering a region slightly larger than the combined area of Alaska and Texas — at a resolution of 2 meters per pixel!

Web viewers can zoom in and out, and pan around an area. The mosaic 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.
