Global planet maps in this folder (tools/build-planet-maps.py; full provenance, hashes, registration evidence and statistics in manifest.json).
Changes made to every source: longitude roll to put 0 deg at the centre, latitude remap to planetocentric, area-averaged resampling, colour handling as stated per map, mean fill of unimaged areas, WebP conversion. No pixel content was painted or invented.
