All The Views

Neat. I did a related project a little while ago. I wasn't interested in how far I can see from everywhere, so much as what I can see from one place in particular. So in mine you can click on a spot and it draws black lines over any land that is occluded by terrain, within 100km. (But all with AI-generated JavaScript, not cool Rust and SIMD stuff) https://incoherency.co.uk/line-of-sight-map/

Cool project! Unfortunately our planet has this pesky (but very useful!) thing called atmosphere, which makes all these extra-long lines of sight only theoretical, I guess? Ok, the longest line of sight is mostly over the Taklamakan desert, so probably very dry air (which might however have some dust/sand in it), but still?

The website claims the longest line of sight in my city is 24.7km from someone's garden that is surrounded by houses. I walk past this particular spot on my way to the gym. I walk downhill from my house to get there. I seriously question the reliability of this data.

I tried the summit of Mt Ruapehu here in NZ and got 358.8 km to Mt Owen. Not bad as I was expecting Tapuae-o-Uenuku which is a little shorter at 342 km. One advantage in NZ is that on a nice day you actually have a good chance of seeing it. Oh ... clicking on Mt Owen doesn't return the favour ... or the other nearest peaks. But Culliford Hill does show a return back to Ruapehu, 355.4 km. Clicking on Tapuae-o-Uenuku also, as expected, gives a line to Ruapehu: 342.3km. Mt Cook is high, but has too many other high peaks near it. Mt Taranaki is isolated, but doesn't turn up any very long distances. I don't expect any other candidates in NZ. Update: actual and accidental photo of Tapuae-o-Uenuku from Ruapehu (342 km), seven months ago. https://www.reddit.com/r/newzealand/comments/1m9p0bh/tapuaeo... And, as pointed out in a comment, also Mount Alarm 2.5 km further. What is the longest in North America? Or Europe proper -- not Elbrus (which I've not been to but have been close enough to see, from several places e.g. from a house in Lermontov (~94 km only), summit of Beshtau (93 km), Dombai ski field (~63 km), somewhere on A157 (~50km).

This is so interesting. Thanks for sharing. I have been working on a similar project where instead of finding all the sights I have focused on finding all the cycling climbs in the world. I think there is a sense of satisfaction in finding ALL of something. Cheers www.climbs.cc
