OpenDtect developers create SEG-Y zip program
Please check out this new very smart SEG-Y zip program as it works great for me. Especially for sending out stuff to Schlumberger, when you have issues with attributes, loading, interpretation, etc. Also good for getting those large cubes onto your FAT32 drives...
Have Fun!
---------------------------------
Bert Bril, one of the key developers behind OpendTect made a little SEG-Y zip program to compress SEG-Y files. The program is available for free f(released under LGPL) from .
Bert claims that the program reduces the most common SEG-Y files to at least 50% without a loss that is detectable in the shape of the FFT spectrum. Higher reduction factors (up to 4x) can be achieved by setting the compression level higher. Some deterioration may occur but the effects remain random in frequency. The program is tiny (like 30kb), so that it can easily be sent together with compressed data. The program removes spikes from the data before compressing. Setting the compression level to zero SEG-Y zip effectively becomes a despiking tool and can be used as such.
