Syntax

   @CoordSys([coordsys-name])
   @CoordSys(__CONVERT_COORDSYS_NAME__, <inputCoordsysAttr>, 
      <CONVERSION_DIRECTION>, <EXTERNAL_SYSTEM_NAME>, <outputCoordsysAttr>)

Arguments

   <coordsys-name>   
   
      The name of the coordinate system for the feature to set.
   
      Range: coordinate system name 
      
   __CONVERT_COORDSYS_NAME__  
   
      This flag if present as the first argument indicates that the function 
      will be used for converting FME coordinate system name into its equivalent 
      representation in the external system and back.
   
      Range: N/A  
      
   <inputCoordsysAttr>  
   
      Name of the attribute that holds the source coordinate system string.

      Range: Existing attribute name   
      
   CONVERSION_DIRECTION 
   
      Indicates which way the conversion is to be done.

      Range: (FROM_FME_TO | TO_FME_FROM)  
      
   EXTERNAL_SYSTEM_REPRESENTATION   
   
      Indicates the external system representation.

      Range: (AUTODESK | EPSG | ESRI | MAPINFO | OGC) 
      
   <outputCoordsysAttr> 
   
      Name of the attribute which will hold the output coordinate system string.

      Range: Existing attribute name   
      
Description

   This function returns the name of the coordinate system where this feature's 
   coordinates are measured. If it returns a blank, it means that no coordinate 
   system has been set for the feature data. If a coordinate system definition 
   is created automatically by FME from parameters read from an input data 
   source, its name will begin with an underscore character (_).

   In conversion mode an empty string will be returned if the source coordinate 
   system does not have a target representation. This could occur, for example, 
   when no mapping exists between an Oracle SRID and an FME coordinate system.

   FME may automatically define coordinate systems. It is possible that there 
   may be two different names for the same coordinate system definition. The 
   result returned by @CoordSys should not be used in a comparison with a 
   hardcoded coordinate system name as coordinate system names may be different 
   but may be structurally equivalent.
