Hi,

I have this proj4 config that I had converted to FME custom coordinate system. However, when I run a reprojection transformer on it, it gives me an error.

Below are the details.

 

Can anyone shed some light on this error?

Thank you!

Proj4 config:

 

+proj=tmerc +lat_0=0 +lon_0=120.95 +k=0.9999 +x_0=446904.02 +y_0=2879827.84 +ellps=GRS80 +units=m +no_defs

 

FME custom local coordinate:

COORDINATE_SYSTEM_DEF ER94 \\

 

PROJ TM \\

 

UNIT METER \\

 

DT_NAME ER94 \\

 

DESC_NM "ER94" \\

 

GROUP ASIA \\

 

SOURCE "ER94" \\

 

ORG_LAT 0 \\

 

PARM1 120.95 \\

 

SCL_RED 0.9999 \\

 

X_OFF 446904.02 \\

 

Y_OFF 2879827.84

 

FME ERROR when trying to reproject:

Datum definition ER94 does not exist.

Hi @lostsoul, thanks for your question!

 

From what I can tell, it looks like ER94 is not a supported datum out-of-the-box in FME. Cross-reference this dictionary. However, you can define a new datum and add it to FME. I think this would resolve the error.

 

Hope this helps!
