Vancouver 3D Workshop Saturday, June 16th, 2018 THE NEED FOR STANDARDS TO SUPPORT 3D STRATEGIES OF GEOLOGICAL SURVEYS François ROBIDA BRGM OGC IUGS/CGI Vancouver 3D Workshop Saturday, June 16th, 2018

Our infrastructures and cities are built on flying carpets

Key challenges for smart / sustainable / resilient cities and infrastructures dependent of subsurface knowledge Geo-Hazards : ground stability, subsidence, earthquake, flooding Resources / services : water, geothermal energy, energy storage, building materials Remediation of polluted soils, urban wastelands … In the context of climate change and energy transition and of increasing conflict of usage of the underground We need an holistic modelling of cities that integrates the subsurface (and the other components of the natural environment as air, water, biodiversity) “City system” (analogy of “earth system”) Geological surveys, environmental agencies are information providers and data custodians

Why is it difficult to merge modelling of built environment and “geology” ? Modelling process Complete design by human Progressive exploration, and understanding (increasing complexity) Data acquisition Relatively cheap (Lidar…) Expensive and ”indirect” Modelling tools CAD engineering software “geomodellers” (interpolation algorithms) Standards BIM CityGML For 2d : GeoSciML For 3D ??? Accuracy / uncertainty Usualy well known (design – construction) Difficult to estimate, communicate, and represent Visualisation VR tools for general public “for experts only” People Engineers Natural scientists

Do we (GSOs) want to be part of the game ?

Some considerations about Geological Surveys strategies We are not mapping agencies (even 2D/3D), rather information agencies « We must not work anymore in a bubble » (Linda Richard – OneGeology meeting) For new customers / users (not only for geologists…) We will deliver new “3D products” : regularly updated, with provenance and traceability, be delivered on demand, easily integrated in different environments or workflows (including machine to machine) Ensuring a better collaboration with academic research on one side and industry on the other side Move from “handcraft” products to more industrialised processes we need to improve our internal processes and better collaborate with partners and customers this is all about interoperability (NATO defines interoperability “as the ability to operate in synergy”) … no interoperability without standards

… so what do we expect from standards ? To exchange between our “pairs” This is what we have done in CGI (GeoSciML, ERML,…) Necessary Takes time Must focus on use cases ( “Lite” versions) To exchange information with other communities (ie BIM for infrastructures) To facilitate the internal processes, (ie production and update of 3D models using a standardized description of geological conceptual framework) To facilitate the reuse of our data in broader contexts (ie AI…) … always need to identify why and with whom be interoperable… … and must be implemented…

​​International ​Union ​​of ​​Geological ​Sciences IUGS/CGI Commission for the Management and Application of Geoscience Information Mission: To foster the interoperability and exchange of geoscience information, by active community leadership, collaboration, education, and the development and promotion of geoscience information standards and best practice

CGI Mission and vision Mission: To foster the interoperability and exchange of geoscience information, by active community leadership, collaboration, education, and the development and promotion of geoscience information standards and best practice Vision: that geoscience information can be exchanged, understood, and used without limitation, that geoscience information can be readily integrated with standards-based information from other knowledge domains, that geoscience information is semantically rich and structured to enable seamless interaction in all environments, that global education about the management, modeling, exchange, and use of geoscience information enables its best possible application, for the benefit of all society.

GeoSciML The GeoSciML data transfer standard was recently accepted by a unanimous vote of the Open Geospatial Consortium (OGC) Technical Committee. This significant milestone cements GeoSciML’s place as an international geological data transfer standard.
