To import spectral data into SMS, do the following:
1. Open spectral data files.
Use File | Open... to open files with spectral data such as STWAVE ENG files (*.eng), STWAVE nesting files (*.nst), CMS-Wave ENG files (*.eng), CMS-Wave nesting files (*.nst), BOUSS-2D directional wave spectrum files (*.dws), and coastal data information program files (*.cdip).
Alternatively, drag and drop the file into the Graphics Window in SMS.
2. Create a Spectral coverage.
3. View spectral data.
Alternatively, spectral data can be imported to a specific location in the project.
