The WinSism program allows you to easily process refraction seismic data with all usual steps. Intercept time, Critical distance, Delay method, GRM computation are supported. Online contextual help, an extensive manual, and demo files are included.
You can pick first breaks on any SEG2, SEG-Y, ABEM Terraloc, BISON, OYO McSeis, or Geometrics ES-1225 data file with a maximum of 120 channels. It is easy to build travel time with any geometry up to 50 shots and 120 receivers. Irregular geophone spread is possible, and elevations can be introduced.
With WinSism you can print B&W and Color scaled copies and Seismic profiles with your Windows compatable printer.
