Topic:
Can you load a seismic line that has a topographic profile on top of the seismic?
Description:
This profile is actually the topographic profile stored as SEGY data. The
problem in loading this file is the amplitude value that was used is
very extreme i.e., -1.0e8 to +8.0e8, so when the data is loaded the actual
seismic amplitude is very low.
Solution:
If you want to see the elevation display on top of the seismic, you will have to
load the line twice.
1.) Load the profile line into a class called "elevation" (0-200 ms for this
line).
2.) Load the rest of the line - the real seismic- (200-5300 ms) into a class
called "stack".
You can now display a "split" Seis2DV screen with "elevation" in the top panel
(displayed VA), and display the "stack" in the bottom panel. This way the huge
numbers in elevation don't wash out the seismic amplitudes. This method,
however, devotes a lot of screen space to an elevation profile.
You can get more interpretation area if you launch two Seis2DV windows, and
display the elevation profile on the one in back, and your seismic data on the
one in front, so the seismic window overlies all but the very top of the
elevation window.
