Hi all,

I was given a fair amount of seismic data (sgy) and except from loading as points on GM is there anything else funky that I can do with them? can I combine them and create something visually presentable etc? Its not the type of data that I usually work with and I understand that the info that they provide is supposed to extend "underground".

I run GM16.2 with LiDAR (I was wondering if the LiDAR module could come in handy as well).

Any suggestions would be welcome.

Thanks all

    Hi Yianni, 
    I don't have an answer but I'm commenting to bring this back to the top of discussions.  I'd like to hear what other GM users have to say.

    Hi Folks,

    Apart from loading location, IMHO there is almost nothing that you can do with SEGY data in GM. The whole point about SEGY is the seismic information in the Z direction (i.e. underground) and GM cannot display other than a simple height/depth Z value. However, I am happy to be corrected. If you want to delve under the hood of SEGY, here is the format descriptor in all its complexity http://www.seg.org/Portals/0/SEG/News and Resources/Technical Standards/seg_y_rev1.pdf.

    If you do fancy getting down and dirty with SEGY data, most of the software is very expensive,  OpendTect provide a free version of seimic software http://www.opendtect.org/index.php/free. I have not used it myself but I know of others who do.

    If you simply want to view the sismic, free viewers are available, e.g. http://www.lynxinfo.co.uk/software-seisview.html.

    Cheers
