setgeom - BSU program sets geometry for reciprocal refraction shooting (run gensetg first)
setgeom [ -h | sfile | pfile | nezfile ]
Basic Seismic Utilities (BSU) applies the shots.txt and phones.txt files created by the interactive program, gensetg. This program is designed to set the geometry on engineering surveys, such as bridge foundation studies. The geophones are layed out in blocks (a group of phones together, say on one bank of a river). The shots move, perhaps across a river (with the geophone to channel relationship being constant the entire time). Refraction interpretation usually involves resorting to common receiver gathers. The two text files, sfile and pfile arguments, direct the association of surveyed positions in the *.nez file with the data files (sfile), and with the geophones (pfile). The association is made by an exact character match of labels (last column in *.nez file). Thus, an entry in the shots.txt file of SP04 will not match an entry of SP004 in an *.nez file (they must be identical, and this is something to watch when you run the pre-process, gensetg.

NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
setgeom shots.txt phones.txt stp001.nez
File the data files specified in column 1 of shots.txt will be associated with shot labels in the second column of that file. The seismograph channel numbers in the first column of phones.txt will be associated with survey labels in the second column. The survey coordinates will be in file stp001.nez.
setgxxxx.seg
named according to input file first 4 characters (see example above).
