The subject is the ability to make accurate up to date maps out of satellite imaginary. I fail to see how this is a counter argument against that.

Eh, SAR and multispectral can characterise more than one would realise about the innards of non-bunker buildings.

This is why I believe the policy of obfuscating strategically important sites in map data is counter productive. If you overlay the Chinese provided obfuscated mapping data over mapping data obtained by your own military apparatus, the "obfuscated" portions of the Chinese data suddenly become "highlighted".

And a domestic government approved mapping service will tell you what’s going on inside a building? Why are you moving the goal posts?
