Who are the OGP?
International Association of Oil and Gas Producers (OGP)
• Formed 1974.
• Members produce half world’s oil and one
third of its gas.
• London office (global affairs) since 1974.
• Brussels office (EU) since 1992.
• Representing some 30 OGP members
active in Europe and 72 worldwide.
Global standards used locally worldwide
The OGP Geomatics Committee
• Formed in 2005 from the European Petroleum Survey Group (EPSG).
• Previously known as the Surveying & Positioning Committee.
• Comprises of specialists from OGP member companies working in the areas
of surveying, geodesy, cartography and geo-spatial information/coordinate
data management.
• It is the single global source for positioning
advice, guidance and formats provision for
the upstream oil and gas industry.

GIGS
Geospatial Integrity of Geoscience Software
• To provide geoscience software developers and users with
recommended industry best practice to:
o evaluate the capabilities of their software with respect to
- establishing and maintaining geospatial data integrity
What is a GIGS software review?
A GIGS software review is a structured approach to
evaluating the geospatial integrity aspects of software
and consists of:
• a qualitative evaluation of the software’s geospatial capability
by means of a series of checklists;
• a quantitative evaluation of the software’s capabilities by means
of test data.
Software developers and users (i.e. both software
vendors and clients) may execute such a GIGS review
and both will benefit from its results.
