Are we talking about `cargo build` here? Because my understanding is that if a lockfile is present and `Cargo.toml` hasn't changed since the lockfile was created then the build is guaranteed to use the versions in the lockfile.

If however `Cargo.toml` has changed then `cargo build` will have to recalculate the lockfile. Hence why it can be useful to be explicit about `cargo build --locked`.

They're extremely close! /ɪ/ literally sits next to /e/ on the vowel chart https://en.wikipedia.org/wiki/Vowel_diagram#/media/File%3AIP...

"Hey", /ˈheɪ/, has a dipthong /eɪ/, so é is precisely the first half of that dipthong. It may feel like it's between the “e” in “bet” and “ee” in “see”, but using the dipthong you don't have to guess it.

Thanks. I can't see what you mean myself. If you could paste the URL when you click on one of those incorrect views, I'd really appreciate it. For instance, this one seems correct to me https://map.alltheviews.world/longest/-115.69589485755283_36...

Oh, that sounds like an error on our part then. I'd really appreciate if you could paste the URL when one of those bad lines is rendered.

It's just a matter of storage costs. Even storing a single line of sight for every point on the planet is over 200GB!

The AEQD projection radiates from the anchor right? Is that what you mean by polar coordinates? This was my first foray into optimising projections so if you have any insight I'd love to learn.

If you know anything about QGIS plugins please feel free to make a brief write up in our issues https://github.com/AllTheLines/viewview/issues

I don't know, but I really want to do it.

I see, thanks. So my thinking is that overly dark areas to the North are caused by _relatively_ low visibility. The heatmap is actually dynamically generated for every viewport. So I agree that there has to be some amazing view from those North faces, it's just that they are drowned out by the sheer enormity of the views on the South face.

If were to use absolute global values for the heatmap, then the Himalayas would just appear as pure, washed-out white.

Does that make sense?

Agreed, pedantry very much appreciated. Website updated!

The thing about the observer height that I always try to remember is that features really close to the observer can make an exponential difference. Like imagine how simply putting hand in front of your eyes can suddenly make the whole world disappear. So in theory, it is possible that a mere change of a few centimeters in the height of the observer could affect a similarly dramatic change in the view.

That sounds really promising. I've made a Github issue to make sure we follow this up https://github.com/AllTheLines/viewview/issues/61

Could you post a link to a view that you think might not be right?

1) So you're expecting to click and see a line of sight that you've seen in real life? Is it just that each point only every records the _longest_, which not be the best or most notable view? 2) As in, in a good way?

Do you think there's any way to automatically create these Google Earth links for each of the longest lines of sight on maps.alltheviews.world?

Oh wow, yes, very curious. I believe that is caused by the cleaning of the original NASA data by the creator of https://viewfinderpanoramas.org/dem3.html So whilst they improved the data, it still isn't perfect.

Ultimately we plan to mix in higher resolution data from different more recent surveys.

Wooah, both "antipoles", I've never thought of that. What a great idea. In theory yes, we have the data, but I haven't begun to consider the maths to figure that out.

244km! Oh wow, I never knew people did this kind of thing. Yeah this is exactly the sort of thing we want people to use the app for.
