Right, I think we need to make that "In current viewport" thing more prominent somehow.

So this is the NZ longest line right https://map.alltheviews.world/longest/173.61386108398438_-42...

One thing to note about finding reverse lines, is that they're not truly mathematically identical because the observer always has a height of 1.65m and the destination is always some point at the surface, therefore 0.0m. It doesn't always make a difference, but it sometimes can.

Yup. I'd think so.

I guess the obvious case is if there's a point near one end that is higher, but less than 1.65m higher.

It really might be better to use ground level at both ends. Or at least the same height at both ends e.g. if there is a person on both peaks.
