添加自定义坐标系统

FME is used in many different countries around the world, and it is also used with a variety of custom datasets within each country.However, sometimes FME’s Coordinate System Gallery doesn't include the coordinate systems that are being used.In these cases, you will have to define the coordinate systems before FME can use them.

To allow sites to add their own coordinate systems, a file of local coordinate system definitions is automatically loaded and made available to each FME session.This file is calledLocalCoordSysDefs.fme, and resides in the Reproject subfolder under the FME installation folder.

It contains a series ofCOORDINATE_SYSTEM_DEF,DATUM_DEF,ELLIPSOID_DEF, andUNIT_DEFlines that define additional, site-specific coordinate systems.You can edit these files to add your own definitions.
