Q: The coordinate system of the projection data is correct, and the longitude and latitude on the map is correct. Why can't the data of longitude and latitude of the same region be superimposed? Why can't it be overlaid with the latitude and longitude data in same region?

A: There are many geographical coordinate parameters. You can export the projection data and the latitude and longitude coordinate system that needs to overlay display. Then compare the two geographic coordinate systems to check whether there are different other parameters. If it is different, modify it and then overlay.
