The topcon2 program converts an *.DAT (SEG-2) file to an *.seg (BSEGY) file, (what egg2seg does above). However, it does this with the aid of an NEZ file which contains the [Y, X, Z] coordinates of shots and receivers. In addition, the command line of topcon2 selects information from the NEZ file and permits insertion of shot and geophone orientations. The online terminal help is as follows:
topcon2 topf seg2f lid shdp is nch vpl vpn ir esh isa isv ira ita topf = topcon file name seg2f = seg-2 file name lid = line ID shdp = shot depth is = shot location number nch = number of channels (nch<66) vp1 = geophone station channel 1 vpn = geophone station channel n ir = shot record number esh = elevation adjustment to be added isa = source polarization azimuth (deg.) isv = source polarization vertical (deg.) ira = reference phone polarization R-axis (deg.) ita = reference phone polarization T-axis (deg.)
