Fascinating, I wasn't aware, thank you. But when I look at Google Maps, the Oyapock river is extremely meandering. Major 180° bends within just 500 ft, e.g.: https://www.google.com/maps/@2.3210582,-52.7667375,16z/data=... Are you sure there's an official survey of every twist and turn, composed of "boundary monuments"? Is there a link to these things or something? It's not really clear to me there's any official "navigable channel" at all. Is there anything you can link to that shows the actual legal boundary if it's made of vector segments? Or do we know if that's what Google Maps uses directly, or if that's what's being used for the length calculation? | ||

However, it's quite improbable that bends like that would repeat at a 1-metre scale, at least because the river itself has a minimum width (or maximum depth it can go, if we assume some incredibly narrow gorge) | ||
