bnez - BSU survey generator for NEZ file (C-Language Version)
bnez [ -h | outfile | n-points | tag | so | yo | xo | zo | ido | dy | dx | dz | did ]
Basic Seismic Utilities (BSU) program for generating a survey file in Northing, Easting, Elevation (NEZ) format. Normally, one would have survey data, but in some cases, it may be necessary to generate the NEZ file from a description of geometry. This program would normally be run at least twice, (once for shots, once for receivers). North is positive y-coordinate, East is positive x-coordinate. The output NEZ file will consist of 5 12-character fields. These are a sequence number, y-coord, x-coord, z-coord, and a tag-ID number. One might first run gensetg to create shots.txt and phones.txt files which will link the BSEGY data files to SP and VP numbers. This program creates the *.nez file. Then one would run the setgeom program which takes the shots.txt, phones.txt, and the outname.nez files, creating headers in the binary BSEGY files. C-Language Version.
Options
|
-h |
Online help giving details on command line arguments |
outfile
First argument is the output file name (ex. abcd.nez).
n-points
The number of survey points being generated in this run (either number of channels or shots).
|
tag |
tag=1, label ID as VP (geophone voltage point). tag=2, label ID as SP (shot point). | ||
|
so |
Initial value for an arbitrary sequence value, initial value. | ||
|
yo |
Initial value of y-coordinate (Northing). | ||
|
xo |
Initial value of x-coordinate (Easting). | ||
|
zo |
Initial value of z-coordinate (Elevation). | ||
|
ido |
Initial value of tagged ID number. Combined with tag on output (ie. VP001). | ||
|
dy |
Incremental distance between y-coordinate points. | ||
|
dx |
Incremental distance between x-coordinate points. | ||
|
dz |
Incremental distance between z-coordinate points. | ||
|
did |
Increment between ID numbers points. |
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
bnez masw0001.nez 62 1 1 0 98 0 98 0 2 0 2
File
masw0001.nez is created. Command line arguments are as
shown. Initial few lines of output looks like this
1 0.000000 98.000000 0.000000 VP98
2 0.000000 100.000000 0.000000 VP100
3 0.000000 102.000000 0.000000 VP102
4 0.000000 104.000000 0.000000 VP104
outfile
Recommend a name ending in nez. Example, abcd.nez
standard output
produces a progress bar
