Summary
A new data format convention was proposed by the software developer (Dr. Choon Park) to maximize the downloading speed and
compatibility between the current hardware design base (that uses the LabVIEW TDMS format) and the software development base
(that uses the ParkSEIS format). Considering the vast amount of data that, when completed, will be coming from the acquisition system
for the pseudo-real-time onboard analysis, there should be a compact data format without unnecessary overhead information that will
allow the software package focus directly on the analysis algorithm rather than spending extra time for data importing. Click for a brief
demonstration of the new format on YouTube. A temporary data format, however, will be used as a communication tool to deliver data
sets already collected by using a similar hardware system developed for other related projects at the Lund University until the hardware
system for this project is fairly ready to be tested with the software package. The KGS format (a modified SEG-Y format) will be used
until then. A field data set collected by using the 48-channel MEMS microphones at the Lund University has been delivered to Park
Seismic for the evaluation, by using the ParkSEIS MASW software package, of the optimum number of channels per longitudinal array
(NCh-opt) and the optimum channel (receiver) spacing (dx-opt).
Modification of the ParkSEIS software, the base software package to be developed into the software packaged for this HMA project, has
started. The first task is to upgrade its capacity to handle the highest frequency from 30 KHz to 100 KHz. This process is currently
being applied to all related components in data import, display, FFT, and the 2D-wavefield transformation module to generate the
dispersion image data sets.
Main hardware components have been specified and the first pricing quote has been received at the Norrfee Tech, AB. It seems the
overall hardware budget (now re-estimated approximately as $35K) is higher than the one originally proposed (~$30K). It has been
discussed to submit an amended budget proposal by shortening the overall project period so that the part of the labor cost can be
reallocated into the hardware budget. This topic will be continuously discussed as the project proceeds.
