How cristan/improved-un-locodes works
This repository is a curated UN/LOCODE data product, not a runtime service. Its central result is a location list with substantially improved coordinate coverage and accuracy; related outputs add place hierarchy and aliases. The README documents combining the base UN/LOCODE list with Nominatim and Wikidata, checking against alternative sources, and manual correction. The tree shows the Nominatim data directory, but not the other source files or the implementation of those enrichment steps, so those links reflect documented provenance rather than inspected code.
