Use the Shot point, Byte pos. spinbox to set the appropriate byte position.

Import multiple files

Geocap lets you import multiple SEG-Y files in one go. Since Analyze and Scan makes no sense for multiple files, they are disabled. A combobox with analysis options is enabled instead. The entries are:

• Normal (files read as is)
• Full auto - Equivalent to both Auto assign shot point and Auto assign navigation.
• *Auto assign shot point - Equivalent to pushing assign shot point button in Analyze dialog for all files.
• Auto assign navigation -Equivalent to pushing assign navigation button in Analyze dialog for all files.
• Auto omit taper on/off - Equivalent to manually omitting taper traces by setting Shot point Min all files.

Coordinates and scaler

Make sure the X coordinate has 6 digits and that the Y coordinate has 7 digits. In some cases the scaler may be wrong, causing the X and Y values to have to few or to many digits. This can be adjusted by changing the scaler multiplication factor.

...

The Z values are usually correct but you can have a look in the EBCIDIC header to see if there is any information about the sample interval or Z-range.

Import 3D seismic

The resulting data set's name in the project is either based on the file name or byte positions in the EBCDIC header. To set EBCDIC header byte positions simply highlight the section you want as data set name. The label between the comboboxes always shows current name.
