Major thumbs-up. I’ve been waiting for this. I think (hope) it will be major.

There is a local business that has been mass flagging negative reviews to have them removed. I am witness to multiple reviews being shaddowbanned after the owner has become beligerant, combative, and hostile towards people online.

I want to report this to google, and if possible, get the negative reviews updated.

If you've ever looked at China in satellite view, you've probably noticed the roads and labels don't line up with the photos. They're shifted by about 300–700 m depending on where you are.

This isn't a Google bug. Chinese law requires maps of mainland China to use GCJ-02, a deliberately scrambled coordinate system. Google's road and place data for China is in GCJ-02, but its satellite imagery is at true GPS (WGS-84) positions, so the two never match.

I made a Chrome extension, China Satellite Align, that moves Google Maps' roads, labels, and places back to their true positions, so everything lines up:

- Roads and labels sit on the satellite photos (map, satellite, terrain and globe view) - Your location, searched places and routes are where they really are
- Coordinates Google shows (right-click, address bar) are real GPS coordinates, and you can search with GPS coordinates directly
- Optional: Street View coverage can move with the map or stay put (uploads in China are placed inconsistently)
- A small GPS ↔ GCJ-02 coordinate converter in the popup

It's free and open, collects no data, and only runs on Google Maps pages. Hong Kong, Macau and Taiwan aren't affected, since Google doesn't shift them. Near a few borders (Shenzhen–Hong Kong, Dandong) some roads and rivers can still be slightly off.

Happy to answer questions!

I was looking at a local rally event. Their site took me to google maps to show me the race paths. Now every time I open google maps on my phone it shows those paths. How do I remove them? Thanks
