Free Software for Vertical Seismic Profile (VSP) Data Processing

DSISoft is a free software package developed by the Geological Survey of Canada for processing Vertical Seismic Profile (VSP) data, operating under MATLAB 5.0 or later versions. The software includes modules for reading/writing, editing, sorting, filtering, and other standard processing operations on various seismic data formats. Using MATLAB's graphical user interface (GUI) editor, users can design interactive interfaces featuring seismic profile display, spectral analysis, F-K filtering, and trace header information plotting capabilities.
