This just seems bizarre. What’s to stop companies in other countries from meaningfully mapping China using satellite data? Can’t they figure out the amount of obfuscation or use AI algorithms to align the maps correctly?

It's a rent seeking scheme. The algorithm is already reverse-engineered and you can download it from your favorite package manager. But in order to operate legally in China you need to purchase the "decryption module" from the surveying department.

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...

It seems that even taking geotagged photos is illegal in China, indeed some camera models automatically disable geotagging when inside China: https://ogleearth.com/2012/05/why-do-panasonic-leica-fujifil...

Thanks for the details. It is always interesting how the most innocent things are seen as danger by an autocracy.

South Korea does it too. It forbids Google from access to its official map. Only local enterprises are licensed to get it. Precisely, the government bans the export of geographical data abroad. Check out the 243rd page of a US government report on trade barrier: https://ustr.gov/sites/default/files/2024%20NTE%20Report_1.p...

None, other than their personal safety (when the person enter China border, that's include Hong Kong), or if they want to enter China market.

Everything which is not allowed is forbidden.

The consequences for them seem a bit more urgent, though, given Seoul lying in artillery range of the DMZ.
