Oil & Gas business decisions, safety of personnel, assets, operational activities, and also protection of the natural environment, are often dependent on having complete, correct, consistent and current information of our operating locations and areas of interest.
Geomatics is the combined discipline of Survey & Positioning and Geospatial Data Management, and provides accurate positioning and mapping support across the full O&G life cycle.
The most recent update about the Committee’s work is available here
Our key work areas
Think the Earth is round? Think again. Actually the Earth – land and sea – is continuously changing shape, influenced by factors such as its rotation, gravity and tectonic movement. Our Practical Geodesy work supports the description of the definitions of coordinates for describing locations on, above and below the surface of the Earth.
In order to improve our industry’s surveying capability, IOGP develops and maintains specialist tools and resources.
The EPSG Geodetic Parameter Dataset is a collection of definitions of coordinate reference systems and coordinate transformations. These may be global, regional, national or local in application. To learn more visit www.epsg.org.
Several IOGP’s short documents give guidance to the industry on geodetic topics:
- Guidance for industry:
- 373-01 Geodetic awareness. A brief overview of coordinates and their reference systems.
- 373-03 Contract Area Definition. A guide for exploration managers and lawyers in hydrocarbon exploration companies who negotiate for licence acreage and for licencing authorities.
- 373-05 Coordinate reference system definition. A guide on terminology and best practice.
- 373-23 Web Mercator. A guide on the use of the Coordinate Reference System Web Mercator.
- Guidance for geomatics professionals:
- Guidance for working in specific areas
We are also the custodians of UKOOA Report: Guidance notes on the use of coordinate systems in data management on the UKCS.
Information about Guidance Notes on other Geomatics topics may be found on other pages of this web site.
Geo-information (which includes location, coordinate and geo-code) accounts for about 80% of exploration and production data. Much of this information is stored in a variety of applications, databases and formats, including the widely used Geographical Information Systems (GIS).
Common geography provides an extremely powerful means to integrate E&P information in support of business decision-making for exploration, new business, construction, field development and decommissioning – in fact every aspect of the upstream life-cycle. We develop industry guidelines, good practices and specifications regarding the use of this data.

Seabed Survey Data Model
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:
- 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).
- The SSDM Version 1 launch presentation (used at ESRI Petroleum User Group in April 2011).
P6 Data Model
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.
The P6 GIS Data Model package may be downloaded here. The zip will unpack itself into the following structure:
Crisis response teams tackling the 2011 Japanese Tsunami disaster and the 2010 Haiti earthquake were helped by access to information generated by a space technology known as ‘Earth Observation’. This view from space can also help the oil and gas industry – and not only in a crisis.
Also known as ‘remote sensing’, it involves using earth-orbiting satellites or dedicated survey aircraft to obtain timely access to information about the status of the surface of the Earth.
The advantages of this technology – both onshore and offshore – include:
- Establishing historic baselines for new developments to minimize health and safety risk exposure to people carrying out routine monitoring operations.
- Allowing timely and effective decision-making during an emergency response
Other applications could include:
- Sea ice monitoring
- Environmental baseline mapping
- MetOcean parameters mapping and derived modelling.
The OGEO Portal, supported by the Earth Observation Subcommittee, creates a platform designed to allow an improved communication between the service providers and the oil and gas companies. To find out more go to http://www.ogeo-portal.eu.
The IOGP’s Geophysical Operations Subcommittee monitors and identifies the need for industry guidelines or standards for exploration, development and production related geophysical operations, with the objective of recommending good industry practice to improve the safety, quality and efficiency, and to develop new guidelines and standards as required. Specific areas of interest include:
- Positioning for geophysical operations, especially seismic surveying, on- and offshore
- ‘P’ geophysical position data exchange formats (P1, P2, P6)
- Drilling hazard site and development route geophysical surveys
- Geophysical instrumentation such as Multibeam Echosounders, Sidescan Sonar, Sub-bottom Profilers and Magnetometers, where they are used for seismic and drilling hazard site surveys.
We promote continuous improvement in the quality of geophysical data used to assess drilling or development risk due to shallow / seabed hazards and also in seismic positioning, in support of increasingly demanding geophysical objectives and the developments in acquisition techniques necessary to achieve them.
We maintain the following IOGP Geomatics Committee guidelines and data exchange standards through regular reviews and document updates in accordance with the IOGP requirements, either in direct control or through temporary Task Force(s):

Geospatial integrity of geoscience software – GIGS
Geospatial integrity of geoscience software – GIGS
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.
