Digitization Software Summary

July 27th, 2010

Well it's been an interesting summer that's for sure. I've got about 2 1/2 weeks left of my internship so I'm beginning to compile all my results into some semblance of a paper. Overall I've tested 3 different digitization software each using different types of seismograms (long period vs short period) at different scanning/copying resolutions. I've generated some digital seismograms using each program for 5 seismic waveform samples - extreme long period, extreme short period, typical long period, typical short period, and noise waveforms at 4 different resolutions - 200dpi, 400dpi, 600dpi, and 800dpi. I've investigated the auto trace vs manual traceability in each program as well as exploring the sampling rate allowed by each. There are definite distinctions amongst the programs and it really comes down to what is desired in the output seismogram that can be the deciding factor in your choice of digitization software.
