I don’t rightly know what it means. Probably what you’d guess it does: a big ol’ pile of good-enough heuristic filters and transformations tuned on a handful of key locations, with a pinch of manual modification.

I was only surprised at the claim that the sentence doesn’t make sense in English, I never intended to imply that the sense wasn’t bullshit. (After the sellout stunt the MAPS.ME creators pulled I generally don’t view their participation as an advantage.)

OSM includes practically any mappable data collected for free, including even Wikipedia entries with a physical location. I assume curating means deciding the relevance of stuff like this and making into a map thats similar to google maps. Curate has also lost a lot of its meaning after ~5 years of ad spam. "This holiday, Lexus presents a curated grifting experience" (leaving in the autocorrect typo, sorry)
