ReverseShift

Switching between coordinate systems

How does it work?

This one page allows reversing the offset in PRC Maps, and works both online and offline.

It works as follows: (1) Choose the coordinate system of origin, (2) paste the coordinates in the coordinates field, or in the latitude and longitude fields underneath if copied separately and click Split or Transform as required, resulting in (3) transformed coordinates that can be copied or opened in a corresponding mapping application right away. It's also possible to go the other way around, or convert from and to GCJ-02.
