Geospatial Integrity of Geoscience Software (GIGS)

gigs_logo_mediumThe company successfully orchestrated the project management of the GIGS JIP.  As such this makes the company uniquely positioned to offer a range of services to both E&P and software development companies.  Whether your interest lies in ensuring the product you purchased correctly handles geo-spatial data or whether you are developing a self-certifying your own product we can assist in a number of ways:

  • Understanding Geospatial Integrity and the requirements of the GIGS JIP
  • How the use the GIGS test data sets +
  • The test data sets were primarily generated for use with section 500 of the process – data operations, and they covered all the five areas, coordinate conversions, coordinate transformation, 2D seismic data, 3D seismic data and well data.

    The self-certification process requires that all common algorithms used within E&P be tested using the test data sets provided by OGP.  However, the range of test data provided is limited.  There will be circumstances where additional test data sets are warranted and the company will provide additional test data for any geographical area required and for any CRS.

    The test data sets can be provided in a range of different formats to suite needs.  The test data will also include the design, creation and delivery of UKOOA and SEG exchange file formats for 2D seismic lines, 3D seismic areas and well data.  Each request will be dealt with individually.

  • Understanding the self certification process +
  • The company provides a range of services to assist with the self-certification of geosciences software.  Self certification is a process that GIGS JIP has published to enable software vendors to ensure that the algorithms and workflows used within their applications meet with industry requirements.

    The process of self-certification can appear daunting and the company can assist the process in a number of different ways from providing general high level advice to actually performing the certification process independently.

    EPSG database – the crux of the GIGS drive is to make the EPSG database the main world authority upon which geosciences software systems derive their pre-defined geodetic parameters.  This database is independently maintained by the OGP and is freely available.  However, the integration of the database geodetic parameters into a geosciences software application requires an in-depth knowledge of the EPSG database design and structure.  The company has been at the fore-front of working with the database and will provide consultancy and training associated all aspects of the database.  Our software consultants will also assist in the provision of services and code to help integrate the EPSG database into your application.

  • Understanding structured software review +
  • Structured software review will ensure that the geo-science software integrity is maintained by examining the compliance of the application.   These guidelines form part of the GIGS JIP deliverables and a company must fully understand the context of the guideline where self-certification is to be achieved in-house.  This review will describe the Completeness, Correctness, Consistency and Validity of all key aspects of the process.  The company considers itself to offer a unique professional service to ensure these guidelines are thoroughly understood.

  • Understanding ISO compliance +
  • The company can provide guidance to understanding the terminology and approach adopted within the ISO/TC211 Standards Guide.  The company has particular expertise with respect to the following documents:

    • ISO 6709 – The standard representation of geographical location by coordinates
    • ISO 19111 – Geographic information – spatial referencing of coordinates
    • ISO 19115 – Geographical information – metadata
    • ISO 19131 – Geographical information – data product specifications
    • ISO 19138 – Geographical information – data quality measures
  • Understanding OGP guidance notes +
  • The company has been involved with OGP (Survey and Positioning Committee) for many years and is considered to have played a significant role in the continued development of products and documents associated with the organisation.  OGP has published a number of guidance notes of which the ones listed below have particular relevance to ensuring the Geo-spatial integrity of Geo-science software.
    Of particular mention are:

    Guidance Note No. Title
    1 Geodetic Awareness
    2 Use of bin grids and coordinate reference systems in workstations
    3 Contract area definition
