SEG-Y Viewer
The SEG-Y Viewer is used to examine SEG-Y files and to specify the location of certain critical keywords during data loading.
The SEG-Y Viewer is made up of:
General Information
SEG-Y Viewer Data Area
The SEG-Y Viewer Data Area contains the raw trace data for the SEG-Y
file.
File:Displays the current SEG-Y file you are viewing.
Data View: Specify which part of the SEG-Y file to display in the data area.
Format:Specify how to present the data in the data area. The most common formats are Integer (32 bit), Integer (16 bit) and IEEE Float (Fixed Point). When examining the EBCDIC Header you will typically choose either EBCDIC or ASCII.
Trace Number:Specify the sequential number for the trace data being displayed in the data area. This is only used when displaying the Trace Header or the actual Trace Data.
Change Byte Offset
to Realign Word Boundaries:This
option changes the starting byte being displayed from byte one to
byte three. This option is most useful when displaying 32 bit data,
whether floating point or integer. Normally 32 bit data will
align on four byte boundaries, but sometimes this does not
occur.
An example would be if your CDP Number started at byte 23 rather than a
more typical byte 21. If you have this set to Zero Bytes you
will
not see the CDP number, but by setting it to Two Bytes the CDP number
will appear normally.
SEG-Y Viewer Keyword Area
The keyword area displays defined keywords in the SEG-Y
file.
This area is useful for examining data that has been stored within the
Binary
Header and Trace Header of the SEG-Y
file. Highlight a keyword before using any of the buttons below.
Edit Keyword:Use to modify the location of a specified keyword in a keyword file.
Edit Value:Modify the actual value stored in the SEG-Y file.
Delete Keyword:Remove the Keyword from the list of defined Keywords.
Graph Keyword:Graph all values for a defined keyword for a specified trace range.
