That mountain ridge trick, how reliable of an identifier is that? I'm not really questioning the validity of its use in this situation, but I'd be curious to know more about the nature of the ridge to gps coordinates mapping. How many ridges map to more than one gps coordinate (albeit at potentially very distant locations, one of which could be excluded if more information is available)? Or is the mapping completely injective? That'd be really cool, a bit surprising, but not infeasible.
Sounds like a fun data science project. (Draw a ridge and get a google street view image whose horizon matches the ridge as closely as possible, maybe? Might be fun to play with!)
- bsurmanski 8y agoI imagine it depends on the resolution. Taking it to the extremes you can imagine the horizon matched by 2 points a straight line slope. That may match many ridgelines. To the other extreme you can imagine a resolution down to the millimeter of the ridge. Catching every stone and tree. I can't imagine many duplicate ridgelines there.
- flatb 8y agoI think they mention they located the mountains not from the ridge outline, but from a tip-off they received about where it all happened, and then they corroborated that tip against the ridge outline, building placement, roads, etc. > After a tip off from a Cameroonian source, we found an exact match for that ridge line on Google Earth
