Which is useless in this day. I was in China last week and Google Map’s street layer was aligned correctly to where I was, but the satellite imagery was not.

This demonstrates that Google already knows the correct coordinates of street in China, including those of an airport finished in 2021. For some reason they have spent no time manually aligning the imagery.

Coordinates on the globe are constant whether China likes it or not, my only guess is that Google doesn’t want to spend time fixing data in a country that blocks them entirely.
