Description
The IOGP P6/11 seismic bin grid data exchange format defines the following parameters for a 3D seismic survey:
- Coordinate Reference System (CRS) and coordinate transformation parameters between global and local geodetic CRSMaster bin grid definition/coverag
- Bin grid origin and increments
- Scale factor of the bin grid
- Nominal bin width
- Full fold definition/coverage
Since the creation of the original P6 format in 1998, Geographic Information System (GIS) has become a common application used by operators to manage, analyse and map geo-information. GIS enables integration of geo-information of which seismic positioning data is an essential component. The requirement to be able to visualize and use seismic bin grid definitions and data in GIS has become increasingly important for:
- Seismic positioning QC (is a bin grid in the correct geographic location relative to surrounding seismic surveys, wells, permits etc)
- Improved spatial understanding of seismic coverage
- Linking survey outlines to documents to enable map based search for seismic acquisition and processing reports
With this in mind, IOGP has developed a GIS data model for the storage and visualization of seismic bin grid definitions that is based on the new IOGP P6/11 seismic bin grid exchange format.
