For my project, I'm working a lot with Matlab program to perform cross correlation over huge amounts of continuous data. The technique implemented in the program is called template matching, and it entails cutting out small five to ten second slices of a waveform that shows a single event and trying to find sections in the continuous waveform that look similar enough to count as a match. Matches in the same places on different stations suggest the occurrence of a true seismic event, which is then noted and located and cataloged for some later analysis. To pick out the templates, I'm chopping up data using SAC, a program currently being maintained by IRIS. I'm still deep in the data manipulation (and even extraction?) phase, so I haven't had much mapping to do. However, I definitely see GMT in my future, and possibly other graphics tools as well when it comes time to start displaying my results.
