in the Catalog module
Select Version of EA Desktop:
SEG-Y Scan is available in both the Catalog module and the File module. These instructions are in reference to the Catalog module.
SEG-Y Scan converts your SEG-Y data files into compressed replicas for quick viewing. The scanning process extracts the set of coordinates, data from the EBCDIC header, SEG‐Y attributes and SEG‐Y cataloging detail. Using the extracted data, Exploration Archives generates images that you can view using SEG-Y SnapShot.
The generated images include:
- Live trace outline for each file
- Amplitude map
- Time sections
- Time slice
- Histogram of trace sample values
Identifying the scan status
In the Catalog module, the Scan Status column in the Files grid indicates whether a file has been scanned or not.
Files in a .sgy format are available for scanning and display a status in the Scan Status column as follows:
- Not Scanned: SEG-Y file has not been scanned
- Scanned : File was successfully scanned and outputs are available for viewing in SEG-Y SnapShot
- Missing Data: The scan process was unsuccessful because data is missing from the file
- Missing Navigation Data: The scan process was unsuccessful because navigation data is missing from the file
