Every map and table Real Worlds is made from. The maps are published by NASA, NOAA and the USGS (most are works of the
United States government; the rest were released by NASA's missions through the Planetary Data System) for anyone to
use with credit; each is credited here. The textures in the download were made from them by the scripts in
tools/realworlds (see Building it yourself).
