Re: [Paraview] SEG-Y seismic data loading

2015-05-27 Thread Léo Pessanha
Google summer of code accepted a project that may add the seismic data
import.

Let's wait!

 A quick Google search yields a few Python libraries such as

 http://segymat.sourceforge.net/segypy/

 Has anyone experimented with any of those? Once someone can figure out how
 to bring the data in, we can figure out how to visualize it.

 Is there a georeference filter/tool in ParaView?

Re: [Paraview] SEG-Y seismic data loading

2015-03-17 Thread Lester Anderson
There is an updated version of the code here:
https://github.com/rob-smallshire/segpy

I only have 64 bit Python, and this needs 32 bit PyGtk - anyway the route
for reading the data is certainly there. The one issue we would have is
that seismic data can be both in Time (Z axis) or depth, depending on
whether it has been depth converted.

In terms of attributes to deal with, there could be any number of
components, including velocity, amplitude, density etc. but most people
just view a colour-shaded amplitude image for interpretation. The wiggle
trace is fine at a smaller scale.

As an import, it would be necessary to be able to either read the time of
Z-scale or define manually.

Re: [Paraview] SEG-Y seismic data loading

2015-03-06 Thread Lester Anderson
Yes indeed David, I am sure it would make an interesting challenge for a
coding exercise. Of course with the SEG-Y format, it would be easier (if
that is the right term) to work on a 2D import first rather than jump into
loading 3D cubes!

I know that with the free GMT software it is possible to read the SEG-Y
data (at least 2D) so I am wondering if there is a potential pathway via
that code? The issues are not simple to overcome, as you need to be able to
extract the positional (navigation) data (and understand the projection
used), and then convert it to a visual format. It would be great if there
was a way of dealing with this import using Python!

Something to definitely think about for a future update.

Putting a SEG-Y data in a more direct way is still in the escope of one of
the projects that i am working on. I did some research not a long time ago
and i found that Richard Strelitz wrote a paraview plugin for reading SEG-Y
data at LANL but he gave up since there was no easy way of retaining the
concept of a trace that is so essential to seismic data at the time he was
still trying. He said that would for some of the files he created but we
lost contact.

Maybe he could help, and instead of starting from zero, maybe there`s a way
to continue his work and save some time.

 This is definitely an import filter that would make ParaView more widely
 used, particularly in industry. Even doing as suggested by Leo, of reading
 the coordinates and extracting the amplitude would still be useful when
 viewing the data in 3D.

 Perhaps this will be addressed in a future release, but I know this has
 been asked for some years back I believe.

 Hi Leo,

 Thanks for the suggestions. What software did you use to export the data?

 Hi,

 I would like to apologize, i do not know how to answer a question in
 the mailing list correctly, i think the way i am doing it right now is
 going to appear as a new question

 There is no easy way of doing it, to see SEG-Y data in paraview, i used
 another software to export the data to ASCII txt

 So i exported to a 4 collumn text file with X Y Z AMPLITUDE,
 imported in paraview, table to structured grid points filter, and used the
 scalar variable amplitude to color the object

 Hope it helped!
