I think both Madagascar and Seismic UNIX should be able to do it. The packages are mostly aimed for reflection survey data but for your use it should work. Plotting is not the strongest side of Madagascar, but there are a few standalone segy viewers that are nicer to work with (but sometimes difficult to install).

**What I am in search of is an open source tool to pick first arrivals, plot travel-time curves, and perform simple velocity modeling.**

I am experimenting with seismic refraction to identify shallow subsurface interfaces. This includes the water table in a sand channel and the sand/bedrock contact.

I have a 24 channel Seistronix RAS-24 for field acquisition. This includes a field computer with software to set geometry, run the survey, and record data to various .seg formats.

What I do not have is a reliable program to process and model my data. Thus far I have been evaluating seismograms in the field and calculating depths by hand with the text book equations.

I am open to any freely available software solution that would allow me to interpret and visualize my field data. This includes python or matlab based packages.

**Are there any open source and community supported seismic refraction processing tools available?**
