GENREF

NOTE: This program is only for BISON data. For SEG-2 formatted data, consider GENSETG 10.1.6 and SETGEOM 10.1.7. This is an interactive program that generates bash scripts for setting geometry when doing conventional “Roll-a-long” shooting, but no survey data are available. The program generates an *.nez file and scripts:

geom run this first, it runs program TOPCON to generate *.xyz files.
geom2 run this second, it calls script go1 which reads the *.xyz files
go1 called by geom2

TIP: Make sure to chmod +x the scripts to make them executable. The following is an example log of a small run:

The labels “SP” are shot locations, the labels “VP” are voltage points (geophone) locations.

The geom file calls topcon 10.1.3 for the Bison files FAC10001 etc., and looks like this:

The go1 script looks like this:
