But Google Maps told me to take a right, in the middle of the Mississippi River. So who's really living in 1984?
The car GPS in the middle of the road there’s the road on the right and left but the GPS says go left points right if it says go right it just points left
Lol I’ve had google maps tell me to exit a freeway, go to the light, make a u-turn, get back on the freeway going the opposite direction and within 2 seconds I had arrived at my destination... 😂😂

This is so true !!! I was in Xiamen, China last year for a 19 hour layover, so I went to explore the city. On my google maps I saw a river with a bridge crossing it so I decided to walk 45 min to explore and see it. When I got there, no sign of any water or any bridges, just a regular city. I was so confused 😭

Nothing says “development of national economy” quite like sending someone 5-10 minutes away from a business’s actual location. What a joke.
This is somewhat misleading in that you won't ever actually face the problems stated in the video. In reality, you use a distorted map with distorted coordinates that sends you to the right place.
@@cong4559 No. It communicates that China is uncooperative and not interested in ease of doing business. After watching this, I don't think I want to go there.
@@runningfromabear8354 Considering the current political attitude from Washington and Trump's banning of Chinese companies etc... I'd say China is not the one that is uncooperative and not interested in ease of doing business. Quite the opposite actually. More people would agree that they didn't want to go the US having seen Trump swing his dick around.
Cong Lu got’em
@@cong4559 The only company that has really been banned is Huawei which has had so much evidence brought against them of spying, stealing designs, and working closely with the Chinese government. Almost everyone agrees with the decision that was made to ban that company. China has been taking advantage of not just the United States but everyone, basically and were just the first ones to take action on it. The banning of this company is completely justified. We are now at a trade war that China knows if they do not get out of they are in big trouble. The United States can hurt the Chinese government way more than they can hurt ours and they know that. Maybe if China would stop stealing IP and trying to spy on us this wouldn't be a problem.

I lived in China for a time, and it's really interesting to see how creative my Chinese friends were in getting around arbitrary things like this. My friends kept mental maps, and navigated by landmarks.
Me, I just used the satellite view, which mostly worked.
I was going to say when I went to China a few years ago and used Google Maps (and other similar apps) to navigate around Beijing, Shanghai etc it worked fine. I was able to find everything, down to particular shops. There might have been a shift of a few tens of metres but not enough to make navigation difficult...

4:53 In conclusion, there's no way to know where anything in China actually is.
But since you can get the Chinese satellite map that has been distorted by the GCJ system can't you compare that to an accurate satellite map, determine how the distortion has been applied and find the appropriate correction, and then apply that correction to street map?
As a programmer, that was my first thought- it sounds very simple to do, but I imagine it's illegal - And companies aren't well known for wanting to be on the bad side of China, considering the population of China is seen as another source of profit, and the companies don't tend to mind bending the knee occasionally.
How you can "determine how the distortion has been applied"? If you don't have actual location of places, unless you are actually in that place and have way to measure it (without being catch by Chinese police), which is probably difficult
@@MaraMara89 By comparing their GPS apps to satellite photos. You can start the calculation of the distortion based on easier-to-recognize landmarks, such as bridges, tall buildings, and highways. It's a really trivial calculation to get usable results.
It's not only possible, it's already been done.
@@weeveferrelaine6973 No, you can't at least if the random number generator used for scrambling isn't a pseudo-random one. If they used cryptographic RNG then you need to know the seed to get what you want. Well unless you want to brute-force every single pixel.

Imagine an entire country’s government being this delusional
Back in the day American maps of the Moscow area were very popular there because they were accurate.
Not delusional, but paranoia. You know, in many Chinese war story, the first thing to do before making war is making map. The CN govt just so paranoia they don't want anybody to have an accurate map of CN, so that no invasion can be effective. But I bet all strong countries like US or Russia have their own military surveillance satelites and can make an accurate map of CN, at least for all important government/military facilities.

@@santiagorappy71 then obviously the Baidu one is wrong :))
fun fact: different maps may use different reference systems. as a sailor/yacht owner, you know that you need to check the reference system of your map. usually all newer maps are in WGS84, but especially with older maps, you have to shift your location by a bit. it's indicated by how much and in what direction though, because the manufacturer of the map wants you to know where you are ^^
In China, please use Amap(Gaode Map, AutoNavi) or Baidu Map. They have the same functions as Google Map, with accurate information and traffic conditions. BTW, Google Map is disabled in China.

Is it possible to figure out the distortion by comparing the satellite images? It drives me nut to think that I live in the middle of some vapor wave coordinates
How about commercial pilots, do they get real maps so they don't hit mountains and all?
Nope. XD
Commercial pilots don't really use "maps" to navigate, certainly not the type of map you would have in your car. Generally, navigation is either conducted using a series of pre-programmed GPS waypoints that the aircraft automatically follows, vectors from air traffic control, radio transmitters called VORs, and in some cases the naked eye or "dead reckoning." (This is only done under visual flight rules, generally in smaller, non-commercial aircraft or on final approach to a runway). Aeronautical charts are used for route planning prior to departure and I'm sure that these are 100% accurate since they do not include things like stores and roads, only airports, dangerous terrain, obstacles, etc. Not to mention aircraft are equipped with several different systems to prevent them from impacting terrain, a building, or another aircraft.

One thing you missed: Chinese gov made this coordinate system very pricey too, there is a huge amount of licensing fee even for the authorized companies to make the map.
the other joke about this is that some incompetent "GIS demo" program was published with source on Google code and everyone learned the algorithm from it

Man this video is incredible I always wondered why the roads layout was always off on Google maps to the point where I go look for maps on baidu ditu instead
All American maps include intentional inaccuracies. Not for military reasons, but so the publishers can prove that somebody else just copied their map instead of making their own. As an example, I once found a map that showed a small dead end road in our hay field.
Eric Farmall1206 To be fair, that’s quite a bit less interference than intentionally scrambling the coordinates of the entire map.
Eric - None of the copyright errors affects anyone: nobody has died, no emergency services affected. Who uses paper maps nowadays?

@@airgliderz except it is! Some maps have "paper towns" which are traps for map copiers.

because CHINA
what?
Communists aren't exactly known for their rational decision making abilities.
Well, acutally most countries do have the right map.
Then why keep it wrong? Just because COMMUNISTE?
Nope, and it's a little bit complicated.
You see, as this wonderful video says, if someone wants a real map, they have to make it themself, (and they often do). And during the process, lots of amateur spies got caught. (Noticablely Japanese commercial spies got caught a lot)
And since those "wrong" maps are designed to protect some important spots, Ex an Uranium mine in the middle of nowhere.
It's pretty easy to caught some foreigners with high-end (sometime even militray grade) map making tools and a real classified map.
It's not always for militray though, for example a detailed mineral map can give huge advantage in commercial negociation when one side know excatly how many tons of mineral left in the mines, (which is feasible with a precise measurement of local gravity), the traffic around the mines(which means its capability) etc.
Just want to explain why those wrong map even exist.
(But do China exist in the first place?)
Ones enemies cannot reliably plan to destroy that which they possess incomplete information about. It forces direct observation.
When I travelled to Shanghai and a few other cities a couple of years ago, I didn’t notice any map variations. I’m not saying that I tested every location for accuracy, but I wasn’t aware of map inaccuracies. Maybe there was and any confusion was written of as translation weakness on my part.
For those wondering, no, the end user does not have problem navigating IF you are using the correct map app. My guess is the algorithm is deterministic and easy to compute one way (from real coordinate to mapped coordinate) but hard to compute the other way (from mapped coordinate to the real one). The map app would translate the received GPS coordinate into the mapped one and display on the app, hence it will still appear correct in the app.
How do I know this? I'm a Chinese citizen living aborad. I never had any issue with Chinese map app when I go back for visit in the past 10 years. Just don't use google map. In fact the best practise is to disable the entire google suite while you are there, otherwise it attempts to contact google server in the background which will never make it through, but drains your battery very quickly.

Are they relying on taxis for everything? I don't see how even locals could travel without being lost every time with using public transit and walking in the cities.
I read in ancient times (pre smartphone) people relied on street sign and asking for directions.
sarvesh lonakadi anyone who have been to China will tell you that this is not a problem at all
@@abcabc-uv6ce Maps come in physical paper too. Maps aren't only in smartphones. Besides, cartography is ancient just as much as just simply asking for directions.
The map is wrong, but will still allow you to find your way around in China following paths and roads, because everything is wrong relative to everything else in China. So path finding works fine.
Everywhere else the maps are an accurate representation of what’s on the ground. If you have a 1:100,000 scale map and blow it up 100,000 times you will have a drawing you can lay over the real world and lines up perfectly. That will not be the case with this map in China.
So you couldn’t use the map for plotting artillery strikes, or walking a bearing.
I went to China and my hotel on google maps was in the middle of an airfield
4:48 if i were to drive across this, would i get teleported from one side of the bridge to the other?
What if you take Google.cn's map and cross reference it to normal google map's satellite imagery and then distort accordingly? Wouldn't you then get an accurate map and thus accurate coordinates? I'm sure you could have some sort of AI algorithm do such

Because they use the shift algorithm for the whole world?
@@postvideo97 They just don't have satellite data at a reasonable resolution that lets you see if the algorithm is used or not, at least for the US.
Baidu is kinda useless for anyone who doesn't understand Chinese though...
@jmarks881 It's annoying to code and no one's had a use case for it.
@@ruedelta big data companies (google, microsoft, facebook,....) do a bunch of stuff just because they can, and because it may eventually be useful for something.
i wouldn"t be surprised if any of them internally already had the map restauration tools, and eventually started selling a tool for recreating complex geometries from images and a few data points, but for use on a smaller scale.
the applications for closer to accurate surroundings in architectural and urban planning concepts are certainly there, enabling workable designs at the competition stage without having to settle on and professionally measuring a specific site beforehand.
Wouldn't some clever programmers be able to crack the algorithm using correct satellite images and the modified ones and trying to match them?
You cannot crack randomness, if the map is distorted at a random degree, a random distance, and some streets and buildings are mirrored or removed, well, you cannot crack it.
@@thomasdahl3083 The distortion can't be truly random, otherwise the process would not be repeatable and it'd be impossible to distort the satellite images in the same way as the coordinates. Sven's suggestion seems viable. I don't think it'd be easy since parts of the images are distorted differently, and you'd obviously run into problems if the Chinese catch wind of your project, but it seems like something that can be done.
@@thomasdahl3083 isn't that how hacking works? Finding a pattern to a seemingly random observation.
Ritwik Reddy I don't know squat about it, but I think it's like when something is encrypted which is basically impossible to crack you cannot intercept it and decipher what's being said.
But if they have their own system with their own maps I guess there is a way.
But then if it's like a server sided system then only said device can shake hands with said gps/map.
But nothing is impossible but using a brute method would probably be impossible but maybe fishing for a clone could work.
But then there's probably another zillion unique IDs they use for that so it would be like winning the lotto but needing to guess 100 trillion numbers correctly is a sequence.
But the people who make this shit have to write it all down somewhere and design it.

GPS was similarly obfuscated but they did it badly enough that eventually there was a workaround to interpolate the correct data

Who cares about engineering some fancy targeting system to destroy one thing when you can just blow up everything and take your target out with it.
Sebastião Mendonça wow piece of shit
@@gggggggggggggggggg161 wow someone got mad over a fucking joke
@@sebastiaomendonca1477 As the saying goes... "You get the most flak when you're over the target"... But your joke could also be considered a simple statement of fact... Because when it comes to blowing stuff up, generally you want to make the smallest boom you can get away with while still taking out your target... Making precise targeting necessary to avoid collateral damage... But when precise targeting isn't possible, it's just easier and less time consuming to use one big boom to guarantee the target is dealt with rather than having to waste ordinance hitting every spot where you think the target might be. Sure... It means collateral damage, but if an enemy is going to use civilians as human shields... That is just another reason to beat them.

I can tell the cover picture used for this video is around Yuyuantan (玉渊潭) - a pretty good lake, need to say.
Omg ty for this vid. I was on Google maps and wondering what this is about.
This is true! My Mother went to china and on maps it said her hotel was in the middle of the freeway

It's really not , no foreign government in its right mind would use google maps to plan an invasion. And there are easy ways around it anyway. This only affects tourism.
Can OSM maps overcome if not fix these inaccuracies?
Is there an estimate for how much this costs their economy?
Alot
LOL
Nothing
Really nothing, anyone equipped with high-level math knowledge can do the same trick.
@@baozhao1870 Operating the transform isn't what I was referring to. It's losses due to poor navigation. Do ships ever bump into each other? Do cars or tourists get lost? Are appointments missed? What is the sum total of all that inefficiency?
I still don't understand what's the point, how does this bring "development of national economy and progress of the society"?
China is really bad at making all kinds of excuses.
It's about spies. It's assumed that the locals would know where everything is and outsiders would need a map. An inaccurate map would slow down their progress if they were hostile.
@@orlock20 No it's about accurate targeting of missiles and artillery. I have a feeling the US has produced highly detailed, highly accurate maps of China. Otherwise the CIA isn't doing it's job. It might have been a nightmare 30 years ago, but modern machine learning could easily match up satellite images with annotated maps to produce accurate military maps.
@@ZBritt92 I don't believe the Chinese government fears a military invasion because that would end in a nuclear war. What the Communist Party spends most of its time and money on is to prevent the Chinese people being influenced by outside forces.
It's just modus operandi of oppressive governments. People wrote a lot of possible reasons in the comments elsewhere, but I think persons who made this decision were just "well, we censor books, movies, correspondence, what people say and write, so why should people be allowed to make accurate maps?"

Man, I can't help but be impressed at the lengths the Chinese government will go to further their agenda.
China simply gets things done. Some of this thing are stupid but if someone with power commands it they move mountains, raise the ground in the sea too make an island or build a wall you can see from space (if you bring a picture). Let's just hope no one commands them to jump from a chair all at once or this whole planet fly straight into the sun :D
While we don’t have laws against making maps for the most part, our GPS system used to intentionally introduce random errors into the data stream of non-military users in order to keep it less accurate than what the military had. For some reason.
@@stewie3128 Actually US once switched off GPS in 1996 during a missile launch in China, that's when China decide to build their own GPS system and their own coordinate system.
@@stewie3128 That's because the US government didn't want other countries using the GPS system for their missile targeting and other military applications. GPS was originally developed for military purposes, thus it represented a very useful tool for other armies. This actually happened in 1999 in a conflict between Pakistan and India. India requested the US to provide truly accurate GPS data for the Kargil area for military purposes, and they were denied. Now other countries can use their own systems for war, therefore making GPS purposely less accurate became pointless.
I think it was the coast guard that was somehow stuck with the lesser civilian GPS, so they funded the development to making it better. What they came up with (dGPS) canceled out the errors introduced by the government.
To play devil's advocate: China's not wrong that if YOU have a map that is sub-meter accurate, any potential enemies ALSO have a map that is sub-meter accurate. And as long as your effectively "mesh distort" algorithm preserves _topological_ accuracy (i.e. which roads connect to where) that is still "good enough" for everyday usage.
The fact that China considers basic cartography part of their national defense to begin with is a different matter, and opinions can differ on whether they "should" just because they "can".
I bet AI can resolve this issue with common landmarks on both the real satellite images and the wrong nav waypoints
Chinese government be like:

2:38 Tbf most countries have a national coordinate system although in most cases the aim is to improve accuracy.
Imagine thinking offsetting a civil map does anything for your protection. If someone wanted to attack some particular place in China, I'm pretty sure their military would have the means to figure out the actual GPS coordinates with their own satellites. Because honestly you need to remember it's not the imagery that's off, just the labels are. But no military in this world would rely on the Google Map label to identify their target. It's like putting a sticky note that reads "door" onto your window and think that now intruders will take hours searching for the lock on your "door" to pick.
"OK, so let's say you're you..."
That's it, I'm outta here...

Not like you have diplomatic immunity when you go there. Technically you could, but in the way that technically the law doesn't apply to people who don't get caught.

@@nils2868 so you can survey the land. There are things you can't scope out with satellite imagery. And because you're in China, you have to follow their laws.

But couldn't you use the data from google.cn and cross-reference it with the data of google.com via an algorithm in order to calculate which part was shifted in what way and reverse it to create an accurate map in the end?
