NASA will make 3D moon data available publicly for both creators and CGI artists. NASA's 3D moon data includes both images and elevation. The release of the data specifically comes from the NASA Goddard Space Flight Center, which had been releasing the data to 3D artists but will now release it publically.
Images combined with depth readings make it much easier to create accurate 3D maps of the surface of the moon. The data was collected by the Lunar Reconnaissance Orbitor, or LRO, which has been orbiting the moon for over 10 years. The LRO has a camera that has photographed the entire surface of the moon. The data is then organized into a displacement map, which changes colors corresponding with changes in elevation.
