Seabed Survey Data Model
Since its publication in April 2011, the Seabed Survey Data Model (SSDM) has become the de facto industry standard for delivering seabed survey data in geographic information system (GIS) format.
Historically, geographical features interpreted from seabed survey data have been delivered in unstructured CAD files. This has made the management, integration and exchange of the survey data and interpretation of results difficult. To address these issues the IOGP Seabed Survey Data Model (SSDM) Task Force was formed in 2010 to define a standard GIS data model for delivery, management and exchange of seabed survey data. In January 2017 IOGP successfully released an updated version of the model (SSDM V2) incorporating the industry feedback received so far.
Version 2 of the SSDM package may be downloaded here (21 MB). The zip will unpack itself into the following structure:
- 1_Change_Log

- 3_Data_Model_Templates
- 2a_GIS
- 2b_SeabedML
- 4_Data_Model_Guidelines
- 5_Symbology
- 6_Metadata
- FGDC
- ISO19139
- 7_ Feedback_Form
The IOGP reports supporting SSDM Version 2 are also available directly via the IOGP library:
- Report 462-01 – Guidelines for the use of the Seabed Survey Data Model
- Report 462-02 – Guideline for the delivery of the Seabed Survey Data Model
Other useful documentation:
- Report 462-03 – Interface between pipeline data models and the OGP Seabed Survey Data Model. The Report provides guidance on the interface between the SSDM and the current version of the industry following pipeline data models: Pipeline Open Data Standard Relational (PODS Relational), Pipeline Open Data Standard Esri Spatial (PODS Spatial) and the ArcGIS Pipeline Data Model (APDM).

P6 Data Model
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/coverage
- 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.

Geospatial integrity of geoscience software – GIGS
GIGS (2021 – coming soon)
GIGS is currently undergoing significant revision and a new version will be released by IOGP in early 2021. Updates in the next release include simplified test series, an online testing platform, enhanced scoring system, consolidated guidance material, modernised and expanded test datasets, as well as bug fixes and error corrections. The new digital GIGS will make it easier to record and review test information and get help when needed. Furthermore, the new release will be more adaptable and flexible to the particular type of application being tested, aligning it with an agile strategy and encourage the use of GIGS in a variety of applicable software and data model development cycles. GIGS will continue to provide a complete and robust quantitative and qualitative evaluation of geospatial integrity and data quality.GIGS is currently undergoing significant revision and a new version will be released by IOGP in early 2021.

GIGS (2011)
The purpose of this Guidance is to provide geoscience software developers and users with recommended industry best practice to evaluate the capabilities of their software with respect to establishing and maintaining geospatial data integrity.
GIGS is a process developed in response to significant concern and user experiences of violations of geospatial integrity of data when using geoscience software, resulting in incorrect results, inconsistent understanding and misleading information for the user community.
The Guidance comprises six items, downloadable below:
- ‘Part 1 – Guidelines’ IOGP report number 430-1, describing the GIGS process. This guidance note is supplemented by a companion MS PowerPoint slide pack (with notes) explaining the GIGS process and business benefits
- ‘Part 2 – Software Review’ IOGP report number 430-2, containing a software review checklist to enable structured testing of geoscience software. This software review document is supplemented by an MS-Excel spreadsheet version (ZIP or RAR) of the checklist, intended to facilitate the execution of a geoscience software review and capture its results
- ‘Part 3 – User guide for the GIGS Test Dataset’ IOGP report number 430-3. This user guide supports a series of data files to be used for testing of the algorithms and data exchange capabilities of the geoscience software. The test dataset is included.
