SPW DEMOs 
View Text Only
We presently have demos for Windows and Macintosh only. Our Windows Demo is a zip file containing both an SPWInstall executable, as well as Demo Data files. It allows you to launch the actual SPW program and work with a sample data set. After downloading Windows SPW Demo, you will need to extract the files and install the self-extracting archive file SPWInstall.exe. There is an SPWReadMeFirst.doc file that will guide you through the SPW installation process. After this you will need to review the DemoReadMe.pdf file located in the Demo Docs folder that will help you work with the demo data.

Windows SPW Demo Now [32MB].
Our Macintosh SPW Demo is a self-extracting archive file. It is a hypercard document giving you a very thorough tour through the entire program. It does not, however, allow you to interact with the program or your data.

A Lab Manual of Seismic Reflection Processing
The European Association of Geoscientists and Engineers (EAGE). has recently published "A Lab Manual of Seismic Reflection Processing" by Roger Young. Along with a complete version of Seismic Processing Workshop, the lab manual contains all of the data files and processing flows used to process a near-surface P-wave survey acquired for geotechnical purposes. The small size and high quality of the data set make for a very educational and interactive processing experience. If you already own a copy of the lab manual, we highly recommend that you upgrade the copy of SPW that was included with the manual by downloading our current offical release.
