Fun fact:
If you use 100km units on Czechia, you get the same as if you use 10m units!
(That is 0)

Makes you wonder, at what point does it stop being coastline and start being the banks of a river?

[pranjalmishra]

Fun fact this is somewhat the fundamental principle of calculus

Here's a simple standard: everyone uses 1 or 10 meters (depends on how reliable it is to view) and we use satelite photos taken at precisely noon local time to avoid tide differences. Remeasure every 10-20 years and that's it.

Such a high quality video! You deserve more recognition!

As an irish person, I can say that the Eastern coast is still pretty rough, but the western coast is just ridiculous.

[auxuriousz]

Its the same effect as the mandlebrod set, where it has finite area but infinite perimeter

[lucakun]

well, or you could just plot it on a graph, see that it approaches a limit and take that limit as the length of the coastline

This has such high production quality you should be getting more views

Coastline measuring is one of the inspirations for fractal studying and perhaps the most relevant natural fractal examples.

In theory, this would also mean that the area of countries is unable to be defined too right?

[planetofgamespog]

How about making some kind of sum to infinity formula depending on the scale used, derived from measuring a small but rough coastline, and use that for all the others instead of tediously and manually measuing the larger coastlines

Edit: Create some kind of mathematical simulation for the tides and other terrain changes that occur through time to account for them

[SimonsAstronomy]

That means that any country with a coastline has ∞ meters

[jaycartwright]

it’s pretty simple tbh, coastlines have a lot of jaggedness to them and so if you measure precisely you’ll end up going round and round a lot, thus getting a really long coastline

[unknownb]

and this is the application of integration where we add very very small parts(dx) of a function

[samuelspace]

This video does a okay explanation but here’s a better one:
1. Coastlines are like fractals they get more detailed the more you zoom in
2. It’s debated where the coast starts and the river banks end
3. a standard measurement doesn’t work it will still be debated where you put the measurement, what length and what you measure, also islands or coasts smaller then the measurement won’t even be counted, making some coasts extremely large while others extremely small to what they actually are

[Oscarpiastriismybrother]

What to do; start measuring at where the sand ends and where grass, concrete, etc starts. You can be as accurate as you like

[HudsonProdutions]

If time was paused then it would be possible

[catgirlm]

bro discovered the entire point of calculus

[darkalex]

A way to solve this issue is grab a flat map and return countries/islands to their real sizes and use a scale that works for every country with a coastline. (Use visible coastlines from the map)
