genref - BSU generates bash scripts for setting geometry on CDP reflection shooting
genref [ no options, this is an interactive program ]
Basic Seismic Utilities (BSU) interacts with the user to produce a set of bash scripts used to set geometry assuming a "Roll-a-long" CDP shooting geometry when no surveyor provided *.nez file is available. Designed only for Bison Format data sets. While similar to genvsp, this program is more limited in that only Bison data are provided for. If you have SEG-2 data, you will want to try the C-language programs, gensetg.c and setgeom.c which can do pattern geometry setting. NOTE: User must change permissions to execute on bash scripts generated by this program. Fortran 77.
NOTES, BISON
FORMAT DATA:
Data files will be named with 8 characters (ABCD0001 for
example, 4 alpha, 4 numeric). In addition to generating an
*.nez file (with coordinates of shots and receivers), bash
scripts will be generated that call topcon and
bis2seg programs. The first bash script, geom,
runs topcon and generates *.xyz files which are later
read by program bhed.
