2. Our infrastructures and cities are built on flying carpets

6. 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

LAND USE AND MOBILITY SYSTEM: Skinny Streets (bottom right quadrant)
ENERGY SYSTEM: Geothermal Park (top left quadrant)
WATER SYSTEM: Microbial Fuel Cell Wastewater Treatment (bottom left quadrant)
PORTRAIT OF THE LIVING CITY

9. 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

(owner of former Gemcom software suite : Surpac…)

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

12. 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

13. … 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…

15. The complementarity of 3 bodies
The home for geology (IUGS)
The connection to the geospatial world
A flagship project for standard adoption

16. ​​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

17. 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.

EarthResourceML Standard Working Group (ERML)
Geoscience Terminology Working Group (GTWG)
Continental groups
ICSU-CODATA ​ ​Commission ​ ​on ​ ​Standards – The Royal Society, London – /15

19. 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.

21. GeoScience Domain Working Group in a nutschell
Joint Domain Working group between OGC and CGI-IUGS
First meeting in Southampton OGC TC (September 2017)
A forum to enhance and organize geoscience data standardization

22. GeoScienceDWG position
Main targets:
Harmonize geoscience data expression and facilitate usage
Stay connected and even propose enhancements to technologies / solutions
Connect people interested in the geoscience topic
Ensure proper connections with other groups / communities inside and outside OGC

24. GeoScience DWG - Interoperability Experiments
Borehole Interoperability Experiment targeting a common Borehole conceptual model
Borehole is a core concept in geoscience
Several existing standards
Cross-countries initiatives on the run to push standard usage (EPOS, …)
3D-4D model discovery Interoperability Experiment targeting definition of metadata for 3D-4D models
3D-4D model standardization is not so advanced
Have to make 3D-4D models at least findable
Cross-countries initiatives on the run to push standard usage (EPOS, OneGeology, …)
