Why develop a Seismic Bin Grid GIS Data Model?
The P6 seismic bin grid standard is spatial in nature as it defines the following parameters for a 3D seismic survey:
1. Coordinate reference system2. Master grid, total, full fold, null fold coverage
definitions3. Bin node origin and increments4. Scale factor of bind grid5. Nominal bin width
Being able to visualise and use the bin grid in GIS has become increasingly important for the following reasons:
1. Seismic navigation QC (does the grid sit in the correct geographic location relative to surrounding seismic surveys, wells, permits etc?)
2. Better spatial understanding of seismic coverage3. Be able to spatially search seismic bin grids for
processing and acquisition reports

Overview of P6 GIS GeodatabaseData Model
• The principles behind the P6 data model are:• Utilise the Seabed Survey Data Model (SSDM) design principles• Keep it simple by using only two feature classes i.e. seismic perimeter
polygon FC (polygon) and a bin nodes FC (points)• Feature classes to contain relatively simple tables that hold the main
information carried in a traditional bin grid definition i.e. P6/98 or P6/11
• Data model created to work in conjunction with the P6/11 format
• Material provided includes:• Seismic bin grid (P6) file geodatabase template• ArcGIS symbology stylesheet• Data dictionary• Guidance note describing the P6 GIS data model • Example Dataset

P6 GIS Data Model ArcGIS Symbology Stylesheet
An ArcGIS symbology stylesheet has been provided to symbolise bin grid polygons and nodes in ArcMap. Symbology will likely be integrated with the SSDM symbology to create an OGP symbology stylehseetfor all OGP GIS data models.
