About rivers #210

Open ftomassetti opened 8 years ago

ftomassetti commented 8 years ago

I just found an old image I generated from public data. Perhaps there are a bit too many rivers (or smaller streams) but this is how they look like in real life.

Bonus question: can you recognize the area?

psi29a commented 8 years ago

Honestly, that looks absolutely amazing. :) With the contours, I can visual a topography map, even reverse engineer one based on this alone.

I'm guessing that is Corsica and Monaco? ;)

psi29a commented 8 years ago

To be fair, I think this is accurate (to a point)... those are all lines of erosion, paths that rain/moisture would follow. While it wouldn't ALL be rivers, it would be creeks and streams even if only temporary.

psi29a commented 8 years ago

Was this with your original river code?

ftomassetti commented 8 years ago

Well yes, but the perfect answer would have been: "this is the glorious Piedmont and the irrelevant lands surrounding it". Close enough anyway :)

Yes, that is great but it is also true that it is difficult to represent rivers: it looks decent here because there is no land represented. I think it would be great to have all these information stored in our world file but in maps showing other elements we could represent just main rivers.

This is not generated from me: the image is generated using the real data on rivers that I found in some dataset from NASA I guess.

But thank you for asking if this was the result of my original code :D

psi29a commented 8 years ago

I only recognized the island outline, and I know that it is near Monaco. I'll be honest, I grew up in/near the Piedmont... (Virginia Piedmont). ;) https://en.wikipedia.org/wiki/Piedmont_(United_States)

I just realized, Piedmont is just French for 'foothill's. ^_^; "The region is named after the Italian region of Piedmont, the lowlands which abut the Alps."

ftomassetti commented 8 years ago

ah ah, that is amazing. We could promote WorldEngine as "Made in Piedmont" then :)

psi29a commented 8 years ago

Technically true! :P

On my machine, with version 0.18 (I didn't find the binary package for 0.19 up until right now) all of the rivers are running from the southeast to the northwest. The river basins in the elevation map, on the other hand, look perfectly reasonable.

psi29a commented 8 years ago

This was fixed in 0.19, it should have been listed in the change log. :)

Aksej commented 8 years ago

Oh, sorry then. I now managed to compile 0.19 and the rivers actually work properly there. Thanks!

psi29a commented 8 years ago

Cheers :)

Are you on windows by chance? That is the only thing holding us back from a release.

We have osx and linux builds.

Aksej commented 8 years ago

Nope, sorry, I'm on Linux.
