About China Satellite Align
THE PROBLEM
China requires maps of the mainland to use GCJ-02, a deliberately offset coordinate system. Google Maps draws its roads and labels in GCJ-02 but its satellite photos at their true positions, so in satellite view they're about 300 - 600 m apart. This extension moves the photos onto the roads and labels.
PRIVACY
• No data is collected, stored or sent. The only saved setting is the on/off switch.
• It downloads neighbouring photo tiles from Google's own tile servers, without cookies or a referrer. Switched off, it makes no network requests.
• It only runs on Google Maps pages.
LIMITATIONS
• Mainland China only. Hong Kong, Macau and Taiwan are left as they are, as they do not use GCJ-02.
• Near borders, a small strip of photos can be off. It shrinks as you zoom in.
• With photos aligned, coordinates Google shows (right-click menu, pins, address bar) are about 500 m off the photo, as on the regular map.
