In a quick surevey I found SU (Seismic Unix,
http://www.cwp.mines.edu/cwpcodes/index.html) which
seems to be able to load SEG-Y format and is written in C.
So that would be a good code base for integration into GRASS
or other GIS.
Unfortunately SU is *no* free software though it
seems that the authors have the intention to have it Free Software
(and they even call it free software).

Is anyone else aware on a SEG-Y format reading module as Free Software?

Perhaps it is possible to get the code from the SU authors if
we ask and explain our intention.

Jan
