We have included with this release USP binary test datasets, in both two and three dimensions.

2D Data Example

We off a 1.6 Gbyte marine seismic line containing 927 shots with 240 channel recording. It is partitioned into 4 files, for ease of download. There is no substitute for real data and rest assured, this is real data.

A sparse sampling [every 100th shot] of this dataset is also available. If your goal is parameter testing, at 14 Mbyte compressed, this makes for a significantly quicker download.

For the challenge of a full 2D processing flow, do download the large dataset. A FreeUSP processing sequence to gather up the pieces might look something like:

#! /bin/csh -f

 tar xvfz 2D_shots1.tgz
 tar xvfz 2D_shots2.tgz
 tar xvfz 2D_shots3.tgz
 tar xvfz 2D_shots4.tgz

 gather -N 2D_shots1 -N 2D_shots2 -N 2D_shots3 -N 2D_shots4 -S |\
 utop -R 927 -L 240 -O 2D_shots

If your tar application does not support the z option then simply gunzip the .tgz files prior to doing the tar extraction.

The full dataset is also available on a series of CDROMs from OpenGeoSolutions.

3D Data Example

Our 3D offering is in fact a directory structure containing both a small prestack 3D model, complete with velocity control, and an example Jobs directory. The model was created by Gary Ruckgaber to test our 3D routines. The Jobs directory, built by Paul Gutowski, contains many example flows.

Enjoy.
