I'm using a coordinate system that is not in FME’s Coordinate System Gallery. I added a custom coordinate system by creating a new .fme file and using the online tool. When I use it in my FME model it give me the message: "Invalid longitude value given for projection origin".
My .fme file has this information:
COORDINATE_SYSTEM_DEF PTRA08-UTM/ITRF93 \\
DESC_NM "PTRA08 / UTM zone 26N EPSG:5015" \\
GROUP EUROPE \\
EL_NAME GRS1980 \\
ORG_LAT 0 \\
PARM1 -27.0 \\
PROJ UTM \\
QUAD 1 \\
SCL_RED 0.9996000000 \\
SOURCE "https://www.dgterritorio.gov.pt/geodesia/sistemas-referencia/regioes-autonomas/PTRA08-UTM-ITRF93" \\
UNIT METER \\
X_OFF 500000 \\
Y_OFF 0
I think the error is in PARM1, but I think it's ok... -27
