JRG, the Resource Geology Seismic Processing System for Java, and Viewmat

The Resource Geology Seismic Processing System for Java (JRG) is a basic seismic reflection processing package with great graphics, record animation, 3-d and crooked-line capabilities, SEG-Y, SAC, and sound file I/O, and a friendly GUI that runs on any desktop or laptop. It lacks muting or migrations.

Senior Undergrad Applied Geophysics Class Lab Exercises using JRG function as basic user tutorials and reference manuals for the software, available on Google Drive here. The refraction and refraction microtremor labs refer to commercial software. You can use other methods, or contact johnnlouie@gmail.com about the commercial software. There are two versions of each lab. The older full versions were meant to be demonstrated during the lab periods and then worked on by individual students for one or two weeks. The newer short versions are cut back to be worked on and answered by student teams entirely within the 2.75 hour lab period.

To run the Viewmat app and start JRG, double-click on the jrg500.jar or jrg2G.jar file. Use the jrg2G.jar version, unless your computer has less than 4 Gb RAM. The source code is zipped into the jrg-src.jar file.

JRG is partly an adaptation of the UNIX command-line-based Resource Geology Seismic Processing System. See https://Louie.pub for more information. That site also links to Applied Geophysics, Geophysical Series and Filtering, and Seismic Imaging class lab exercises that use JRG.
