The LROC team assembled 10,581 NAC images, collected over 4 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 of the Moon (2.54 million km², 0.98
million miles²) slightly larger than the combined area of Alaska (1.72
million km²) and Texas (0.70 million km²) -- at a resolution of 2 meters
per pixel!
