This module provides tools to read, write, process, and plot 3D reflection seismic data. The documentation can be found here.
To use this package you must first install the Julia programming language. Once you have Julia you can download and install the Seismic package by typing Pkg.add("Seismic") on the Julia command line.
Once you have installed the package you can type using Seismic to start using
the functions. For example
using PyPlot,Seismic
param = ["nt"=>500,"nx1"=>500,
"tau1"=>[0.4 1.0],"tau2"=>[0. 0.],"tau3"=>[0. 0.],"tau4"=>[0. 0.],
"v1"=>[3500. -4000],"v2"=>[99999. 99999.],"v3"=>[99999. 99999.],"v4"=>[99999. 99999.],
"amp"=>[1. -0.5], "f0"=>[20. 20.]];
d = SeisLinearEvents(param);
plotpar = ["style"=>"overlay",
"wiggle_trace_increment"=>10,
"xcur"=>0.8,
"vmin"=>-2,"vmax"=>2,
"aspect"=>"auto",
"xlabel"=>"X","xunits"=>"meters","ox"=>0,"dx"=>10,
"ylabel"=>"Time","yunits"=>"seconds","oy"=>0,"dy"=>0.004,
"wbox"=>8,"hbox"=>5,
"cmap"=>"seismic"];
plotpar["style"]="color"; plotpar["title"]="color"; plotpar["name"]="plot1";
SeisPlot(d[:,:],plotpar);
plotpar["style"]="wiggles"; plotpar["title"]="wiggles"; plotpar["name"]="plot2";
SeisPlot(d[:,:],plotpar);
plotpar["style"]="overlay"; plotpar["title"]="overlay"; plotpar["name"]="plot3";
SeisPlot(d[:,:],plotpar);
will produce these three .png files:
