The SEG-P1 reader module produces an FME feature for each line in the SEG-P1 input dataset with the exception of header information, which remains unread.
This also means that although coordinate system information may be contained in the file header, it is not parsed or interpreted and thus no reprojection can occur unless the coordinate system is known and specified by the user in the FME user interface. The SEG-P1 reader reads individual files but can be given a list of several files to read in one translation.
