The product of overflights, satellite balloon and aircraft, were absolutely used for cartography. NIMA (now NGIA) spent lots and lots of time making maps (how else would SAC find their way to the ICBM complex at Laputa?).

'Topographic map non-linear confidentiality algorithm')[21] is a geodetic datum formulated by the Chinese State Bureau of Surveying and Mapping (Chinese: 国测局; pinyin: guó-cè-jú), and based on WGS-84.[22] It uses an obfuscation algorithm[23] which adds apparently random offsets to both the latitude and longitude, with the alleged goal of improving national security.[

- tablespoon 5y ago> So does the US and every nation that can. That's just plain not true. IIRC, China is the only country that mandates the use of an obfuscated coordinate system. The US certainly doesn't (and no, selective availability doesn't count, it was an entirely different thing).
