So tell me /x/, what do you think about the catacombs that are hundreds of feet underneath paris.. there are over 400 kilometres of tunnel, and has a maze like structure to its entirety. there are still areas unexplored down there, hundreds of kilometres of tunnel unexplored, over 6 MILLION bodys in the catacombs some areas they're stacked gracefully making beautiful somewhat unnerving designs, others it appears they've been just tossed to hurry the process. There are many cases of people going to explore the catacombs and never have been seen again, or other cases where the bodys are found years after. wouldn't it be fucking terrifying to have your light go out down there? zero light, and I mean ZERO light for hundreds of km's in a maze. Anyone have any stories about the paris catacombs ?
Not only paris has catacombs, amsterdam and other european cities have these :p
Wanted to explore them once but everyone i know where to scared to explore.
The plan now is get these bitches to amsterdam get them as stoned as a canarie and say he look there they have good space cake.
And let the exploring for the artefacts begin.
My masterplan cannot fail.
Can't remember the name, but the entrance was at an old drain output (most of the time there is a lock on the gate but with some tools it should be easy to get in) all i remember was that it was a log from an urban explorer, going to look if i can find it.
>zero light, and I mean ZERO light for hundreds of km's in a maze. Anyone have any stories about the paris catacombs ?
Yeah, it would be terrifying because pic related would likely happen.
If you want source of pic just google ''girl lost *filename*''
Not catacombs, but I've been to the Sedlec Ossuary, it was pretty neat
While it's sad that people die down there, I can't say I have much sympathy for them.
You really shouldn't be wandering in unmapped subterranean spaces like that unless you're an experienced spelunker, and even then it's pretty dangerous.
exactly, my worst fear would be the realization that I'm completely lost and chances are I'm going to die of starvation all the while having the creep factor of being in total darkness surrounded by millions of spooky skellys
this, there are so called "cataphiles" that frequent the catacombs, whom slowly map out the catacombs by repetitive visits, each time mapping a tiny bit more of the underground maze, with so many turns and corners and rooms, even those cataphiles have only seen a small portion of it all, it leaves you wondering what is down there that hasn't been stumbled upon yet. I'm sure with the proper team you could map the entirety of it , but you would definitely need the resources to do it, a flashlight and your buddy tom won't do the trick lol
Are you kidding? It's almost impossible not to. They fall into your backpack and your pockets, skulls all in your boots when you're trying to walk. In your hair. Skulls...
The real question is, "How do I resist playing the skulls like a xylophone!"
They should start a Kickstarter campaign to get funds to map and document the catacombs. It would make a great documentry too.
Isn't there a hand crank light available where you just crank it up to charge it and you have infinite light source? Then it's just food you need to worry about.
Imagine a reality tv show filmed down there. 10 survivors are taken blindfolded into the tunnels, with nothing but a hand crank light and enough food for 1 month each.
Police found a fully functioning movie cinema in one of the catacombs caverns. It included a fully stocked bar/restaurant and its own receptionist desk with automated CCT cameras.
I wish I knew every corridor down there, would the government of paris allow me to run a self-driving 3D scanner down there? I'm thinking of making it and trying to find a radiowave that reaches through at least 7 catacomb floors to instantly pass the data to be explored digitally.
I've found(on the internet) an entrance right beneath the park MontSouris https://www.google.nl/maps/place/Parc+MontSourisemail@example.com,2.3367341,15.83z/data=!4m2!3m1!1s0x47e671a3c64e8b37:0xdd96fc2f479adb1
There's an old unused railway beneath the park, the entrance will be obvious when you walk past it(a hole in the ground against the wall of the tunnel)
That is definitely excellent information and I thank you for sharing but that just moves my statement's goal posts to,
"Damned it would be kick ass to be in Paris right now!"
But this is still a fascinating read, good thread!
Why wouldn't I? I can be anyone for as far as you know. However, I've been a graphics programmer for the past 10 years and have a passion for technology/circuits. It would be a nice project right?
YES!!!! I'm fascinated by the catacombs if you are at all interested in going where no tv show will take you check out this great channel this dude knows his shit bra https://www.youtube.com/channel/UCC8lnipiY6mqcB3v0aBfEGA
Why would he need any of this? He doesn't have to build the scanner from scratch by himself, nor is he trying to model the catacombs purely from abstract algebra. I think you're exaggerating the skills needed for someone to run a 3d scanner.
They're spooky as fuck. I remember a video that scares the shit out of me as a kid, I saw it on Scariest Places On Earth or something. Some guy was lost, and he was just walking around the catacombs, filming stuff. Eventually the realization of his situation set in and he started running. He ended up dropping the camera and you watch his legs disappear into the distance, then the camera just sits on the ground rolling until the tape runs out.
If someone here tells me that video is fake, I'm gonna be miffed.
I seriously doubt someone would be able to create a scanner that "reaches through at least 7 catacomb floors" without having some idea of spectral analysis and electromagnetic waveforms.
There's almost no skill required to run a 3D scanner, at least a modern one.
Source - I work for a survey company, we have 3D laser scanners to as-build plant sites, leases, bridges and anything else the client wants. They're mounted to drones that fly GPS routes we program beforehand. Buddy's just being a prick.
Think again, anon.

Oh typically 4chan
>Someone says stuff which makes him look better than the avarage human
>lets try to look better than him because I'm so insecure about my own potential
Come on man, I'm not even trying to make a statement here, I'm just trying to talk with others about our passion for the catacombs.
Well science is all trial and error, if it doesn't reach through 7 catacomb floors we will have to find other ways but let's try the most useful thing first right? If you know more about spectral analysis why don't you join in on this project instead? It's quite easy to change a location(of the scanner) and a set of vectors(distances and directions to walls) to a 3D shape.
So where's the problem in thinking of making it? I have at least 40 other projects in mind and a few on paper(which I am also thinking of making)
All he'd have to do to build one is buy a drone, buy a scanner, mount said scanner to said drone. I'll concede that cresting something that can penetrate seven floors would be far fetched, but stop acting like you need an engineering degree to bolt a 3D scanner on a drone.
Oh what did I just found? is this really a program that turns photos to a 3d shape?
oh and what is this? an extensive guide on how to turn photos to a 3D shape? http://wedidstuff.heavyimage.com/index.php/2013/07/12/open-source-photogrammetry-workflow/ it certainly is impossible to do!!!
You clearly have no idea how such a thing would work.
Also, what's this about potential? Look at your "40" ideas you're never going to accomplish.
I'm sorry if I came off as dickish, but that's sort of the site's culture. I enjoy the talk about catacombs but what you said was completely ridiculous.
Hey idiot, I think there's a difference between surface data and volume data. I don't know though. Maybe there's some difference between a radiowave penetrating solid earth and yielding a useful signal that will construct information about a volume and inferring a surface from a set of photographs. But who knows. They sound pretty similar.
It's closed due to the filming of as above so below. They used cement before, to close the entrance. But now they've put up a heavy fence, covering the whole tunnel.
We used to use that one alot, since its a pretty good spot for several rooms. If anyone got any questions about the catacombs, feel free to ask.
Pic related, one of the entrance in Parc Montsouris
I'm working on 3 of those ideas so you're jumping to conclussions. If it doesn't work I'll just have to do it another way right? The easiest way I can think of is simply sending the data through wifi to my phone or laptop(in that case the 3d scanner/drone is the wifi spot and I already worked on that a year ago) I would have to follow the scanner which is less lazy than sitting in a park letting the scanner do the job.
Surface data is probably a model and volume data is probably voxels, by using a marching cubes algorithm you can turn voxels into surface data. There's also a ton of algorithms to change a point-cloud to surface data which is probably the easiest way to show it on a computer, directx and opengl have been optimized for surface data for ages
Ah that's a shame, I think it would be the smartest idea to look for cataphiles in paris and maybe they will help out. Throwing all this information on the internet isn't the most secure way to treat sensitive data such as entrances that are unknown to the government.
Does anyone ever try to get jobs with whatever aspect of Parisian city maintenance is involved with maintaining the locking down the area?
Coz some of this involves some also scary looking impromptu spelunking, although I suppose that's part of the fun.
I love this kind of stuff:
Just found this video which is pretty cool but I was looking for one that I saw posted on here years ago with some people in the Paris catacombs who knew where they were going and they found cool landmarks and showed them in the video. One in particular that I remember was an ornate miniature cathedral (think doll house size) but it was made of stone and really cool looking. Anyone know of the video I'm looking for?
But that's already happened to at least one person
Here it is:
can't upload the full quality 6mb
Went there a few years ago. Catacombs were cool but super creepy.
They even had a stone altar down there where the monks would perform mass for the dead.
Couldn't help but think the altar was the perfect size to sacrifice people on.
Okay, at most I know this is a map made for the gypsum and limestone mines which were later turned into the catacombs. I had no idea where the water reservoir was.
At supplied image I marked the public catacombes with red and the closed-off parc montsouris entrances in yellow.
Is part of the water reservoir circled in blue?
Heres the reservoir on my maps. Will have a second look at the computer later man.
I am going to need the screen cap of the thread of the looter on /b/ who tried to prove the thread was real by skull fucking the skull, I know someone has it...
You'll love this then. - Spooky Skellys.. well except 1 now lel.
I've read some articles and it seems 4g is using 700Mhz, however as far as my experience goes it doesn't reach through a thick layer of concrete, maybe it will when the 4g spot is closer by than the general 4g network.
I've got another idea, would any cataphile be interested in an cloud-based dynamic map service? I can make an android app which keeps track of your location when gps signal is available and estimates a position using the accelerometer and gyroscope when there's no signal. Users will be able to modify the map when new corridors are found or closed off. I want to add the feature to take a photo and show the catacombs in 3D. To show it in 3D I can track the movement lines and create a 3D model based on those lines. So it would by default be something like a 1 by 2 meters corridor unless cataphiles modify the size to a more accurate one. The photos would then be projected onto the 3D model which renders a nice estimation of what atually is down there. This would be a win-win project as the cataphiles can instantly share map data and we will have the catacombs mapped in 3D space. If someone can forward me to a good catacombs forum(I can barely speak french though) that would be great.
