OWN_SOURCESconstant
The package's own data, as sources, written from the rows of NOTICE.md: chikyu-pictures (the whole-Earth pictures of the realistic Earth: day, night, clouds and water) and chikyu-tiles (the finer map tiles cut from NASA's bigger maps).
A test holds that none is non-commercial or share-alike, so the package can pass all of it on under the MIT licence. A view's credit line is written from these and from the sources a caller handed in.
