Introduction
The Coordinate System Settings dialog box supports the creation of coordinate systems by EPSG Encoding. European Petroleum Survey Group (EPSG) is responsible for maintaining and distributing dataset parameters for coordinate reference systems, as well as coordinate transformation descriptions. There are different combinations of ellipsoids, projection coordinates, etc., which correspond to different ID numbers. This number is called EPSG Code in EPSG. It represents information such as specific ellipsoid, unit, geographic coordinate system or projection coordinate system information,and so on. You can get corresponding coordinate system information through EPSG code.
Basic Steps
- In the Coordinate System Settings dialog box, click the Create New Coordinate System > Obtained by EPSG Encoding to open the Obtained by EPSG Encoding.
- In the dialog box, enter EPSG code. EPSG Code is a professional parameter. Each coordinate system has a unique EPSG Code.
- Click OK. And then a coordinate system in the EPSG code will be added under the Custom group.
