General

• Include all files that are still relevant in your current package, not just the new files
• Include a separate navigation file for each SEGY
• Avoid nonstandard SEGY headers, or upload a header description document
• Ensure Shot Points/CDPs/CMPs are consistent
• Provide complete metadata
• Include a name, not just an institution, in the Data Owner field
• Don’t include ReadMe or other texty files; files should be self-describing
• Use the navigation buttons, and avoid the back button, in SSDB

 Georeferencing

• Use decimal degrees latitude and longitude in metadata and within files: -90 to 90 lat and -180 to 180 lon, WGS84 georeferencing
• Double check lat/lons, especially the sign
• Use appropriate geospatial referencing (e.g., line for SEGY data, bounding box for maps).
