Every height on this page is a measurement somebody else made. The files are the plugin's own (data/SOURCES.md has every product, its URL, its checksum and what was done to it); the globes are served here at half the plugin's resolution, made from its files by demo/tools/make_worlds.py.

The idea is Sebastian Lague's, from I Made a Pen Plotter to Draw Maps of the Moon; no code, data or imagery of his is used. The rest of the plugin's debts are in ATTRIBUTIONS.md.
