Why do we see some of these behaviors within China maps, outside China? > .. the obfuscated coordinate system for geo-aligning maps .. https://goo.gl/maps/Qr2

Why do we see some of these behaviors within China maps, outside China? > .. the obfuscated coordinate system for geo-aligning maps .. https://goo.gl/maps/Qr2QRB7aB2jrg9Rk7 https://goo.gl/maps/Qr2QRB7aB2jrg9Rk7 Roads are not aligned to the satellite imagery for example.

The same exists elsewhere, in South Korea that I know of. Bridges and dams disappear or move on maps, Google Maps doesn't have high res sat pictures, etc. Just to say, it's not great IMO but not only totalitarian states have a need for such obfuscation; healthy democracies too.

  what is the need that justifies this exactly?

    missiles and artillery can't remote-boom-boom if you can't know where they are

      North Korea won't think to look at other maps?

        Of course not! They choose their targets using Google Maps: nobody was ever fired for using Google Maps! :D

      Perfect for those apple-maps guided bombs.

        In a recent Donbass conflict, there were reports of Ukrainian military and militia using specially tailored Android apps with OSM data as base layers.

        If you can get perfect coordinates from Apple Maps and your missiles have GPS, you're good to boom. It's not as though the missiles have an iPhone inside them.

        But if your missiles have GPS surely you have satellites to get the coordinates yourself?
        Veen 5y ago
        I don't think that follows. GPS access is universal; accurate mapping data is not. These rules are an attempt to ensure that precise coordinates for key targets are not available to anyone with a satnav system or smartphone.

  > Bridges and dams disappear or move on maps, Google Maps doesn't have high res sat pictures, etc. Not defending what I see as childish China the slightest, but one should be aware that even the best democracies don't necessarily publish entirely correct maps, and it is on purpose ;-)
