Role of the Chair OGP - update by Richard Wylde Geodetic Advisor, ExxonMobil Chair OGP Geomatics Committee User needs on energy and minerals data and services Energistics W Europe Region Meeting 31 st May 2011 London, UK

Who are the OGP? Formed Members produce half world’s oil and one third of its gas. London office (global affairs) since Brussels office (EU) since Representing some 30 OGP members active in Europe and 72 worldwide. International Association of Oil and Gas Producers (OGP) 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. Global standards used locally worldwide

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.

The GIGS Review Process To facilitate ease of understanding, the review process has been split into a number of aspects, for each of which a test procedure has been defined: 1.Documentation and Release Notes 2.Pre-defined Geodetic Parameter Library 3.User Defined Geodetic Parameter Library 4.The User Interface 5.Data Operations 6.Audit Trail 7.Deprecation (related to use of EPSG Dataset – see section 2.5.1) 8.Error Trapping These aspects are reflected in groupings, referred to as Test Series. The individual tests are numbered for the purpose of reporting
