- Each pixel represents 2 meters.
- The map is made up of 681 billion pixels.
- To make the map, scientists collected 10,581 images over four years. The final map is a mosaic of those images.
- To gather each individual image, cameras on the Lunar Reconnaissance Orbiter take a picture of the same latitude once every two hours over a month. As the moon rotates underneath the orbiter, this brings each part of the latitude within view of the cameras. The result is a "collar" mosaic, below. This technique ensures similar lighting for different parts of the map.
