Writing of P1/90 files is handled by the P190 writer module. The P1/90 writer creates and writes point feature data to P1/90 files into the folder specified by the DATASET directive. Existing files with the same name specified are overwritten with new feature data. It supports conventional and non-conventional 2-D offshore surveys and conventional 2-D onshore surveys.
The required header record types, 0100 to 0800 and 1200 to 2000 inclusive, will be populated using respective attributes. The coordinate system must be specified on the writer.
