Man the author did not have to resort to such a click baity title to get people to read. “Why Google Maps can’t map China” would have been accurate and not droll. I just opened Apple Maps and it looks perfectly fine. Tested about 10 areas and even rural areas and there was no issue. Stopped reading immediately after. I have no interest in supporting this crap.

Holy shit. I can't believe they created an adversarial mapping standard. That is insane. It really paints a picture of their worldview I think. The oppressed "middle kingdom" under siege. Wow, what it must be like to have that view that everyone else is against you, and you have to bulwark yourself at every opportunity. Yet somehow, balance that with the "historical trend of opening up". It's a scary attitude, and must be scary to try to implement it.
I never saw China like that before. This 1 article changes my mind about a few things. Even the map math is preparing for war! I kind of feel sorry for them. It's been like 70-some years but their war is not complete. And scary for the world: I hope they don't have to seek a cathartic resolution of whatever internal conflict they have by projecting it externally.
I don't see them like that, but details like this add support to that idea, I think. I had no idea maps were like this before today.... :(
Tho reading some other comments, it seems it's not so hard to undo this...maybe this is not really about war or such attitude tho...but then why? Why add that specialness to make it that much harder for people ? That in itself could speak volumes. It's a map, it's kind of representative of a national idea. How can you be for "opening up" but you make your maps different to everybody itself, and not necessarily better! Hahaha :) Maybe I'm just misunderstanding it.. haha :)
Here’s where it gets interesting — GCJ-02 is based on WGS-84, but with a deliberate obfuscation algorithm applied to it. The effect of this is that there are random offsets added to both latitude and longitude, ranging from as little as 50m to as much as 500m. Holy shit.

I honestly don't know why companies simply don't implement it. It's not really "secret" -- or if it is, it's an "open secret".

The standard has been reverse engineered before: https://github.com/googollee/eviltransform I honestly don't know why companies simply don't implement it. It's not really "secret" -- or if it is, it's an "open secret".

The consequences for them seem a bit more urgent, though, given Seoul lying in artillery range of the DMZ.
Yes, I'm sure obfuscating Google Street maps will prevent DPR artillery from accurately striking targets in Seoul.
So Openstreetmap must be illegal in China! And indeed it is: https://wiki.openstreetmap.org/wiki/China Of course that doesn't stop people from mapping every bench in China https://www.openstreetmap.org/search?query=China#map=3/33.99...
Indeed, despite its apparent illegality, China seems to be fairly well-supported and well-mapped by OpenStreetMap, at least in major cities. And is entirely mapped in normal WGS-84 without the obfuscation problem. In any case, according to Wikipedia, open-source code is available to convert between WGS-84 and the obfuscated GJC-02 coordinates. Since technology seems to have caught up with it, is there any advantage (…

Given some of the genius contraptions and tactics that the Russian Army has been caught using in Ukraine, I wouldn't be surprised if it actually did. Also, infosec isn't binary. Obfuscating Google Maps might not prevent the DPRK from doing terrible things to Seoul, but not obfuscating it would probably make it easier for them to do so.
This may have gone past me (I mostly remember the highly non-genius tactics), do you have some examples?
