SeisProcessing.jl

This package contains Processing tools for SeismicJulia project.

At the moment, it is updated and tested against Julia v1.

Installation

To use this package you must first install the Julia programming language. Then, run the Julia application and add the package

julia>using Pkg
julia>Pkg.add("SeisProcessing")

or

julia>]
pkg> add SeisProcessing

Finally, in the julia prompt type

julia>using SeisProcessing

Basic usage

Please, direct to the folder examples. Also, the following code produces the figure below.

using PyPlot, SeisProcessing
dt = 0.002;
w1 = Ricker(dt=dt);
nw = length(w1);
nc = floor(Int, nw/2);
t1 = dt*collect(-nc:1:nc);

w2 = Ormsby(dt=dt, f=[5.0, 10.0, 30.0, 55.0]);
nw = length(w2);
t2 = dt*collect(0:1:nw-1);

w3 = Berlage(dt=dt);
nw = length(w3);
t3 = dt*collect(0:1:nw-1);

subplot(131)
plot(t1, w1)
axis("tight")
xlabel("Time (s)")
title("Ricker wavelet")

subplot(132)
plot(t2, w2)
axis("tight")
xlabel("Time (s)")
title("Ormsby wavelet")

subplot(133)
plot(t3, w3)
axis("tight")
xlabel("Time (s)")
title("Berlage wavelet")
