Q: How can I transform a planar coordinate system with no projection into latitude and longitude coordinate system?

A: The planar coordinate system with no projection can be converted into a latitude and longitude coordinate system by the means of registration. There are two methods for registration: (1) If there is already a reference layer, open the registration tool, set the registration layer and reference layer, and then puncture the same place in the registration layer and the reference layer, select the appropriate registration method, and perform registration. (2) If you already know the latitude and longitude coordinates of some points on the registration layer, open the registration tool, set the registration layer, and leave the reference layer not specified, pick control points on the registration layer, enter the correct latitude and longitude coordinates, select the appropriate registration method, and perform registration.
