Hi,

i am trying to read a segy file.

the coordinate are ok but the attribute no.

They show weird character (maybe encoding?)

How can i configure that? I can't find any option on segy reader.

Is this possible?

Thanks.

Looking another segy file, it seems FME don't look the information on byte 72-73 (Scalar to all coordinates). This byte has an multiplier to all coordinates. Usually this is used to indicate how many decimal places the coordinate has. So, if in byte 181, the value is: 189543256 and in byte 72-73 the value is -100, the coordinate is: 1895432.56 (dot is the decimal separator).
