Updates on models exchanges in EPOS 104th OGC Technical Committee – GeoScience DWG session Southampton, United Kingdom Sylvain Grellet - BRGM GeoScienceDWG 14 September 2017 Copyright © 2017 Open Geospatial Consortium
Copyright © 2017 Open Geospatial Consortium Starting point Model : 3D, 4D, geophysics… Model discovery/description This is not metadata in the ISO 19115 sense A model is considered as a feature Not starting from the 3D visualization point of view (the usual approach) We truly miss model catalogues in our organizations !

Descriptive Information - Different levels of detail and purposes Summary, descriptive information VS detailed ones identifier: resource.geus.dk/ddd/ModelB name: Bunken, Frederikshavn 2011 (Dynamisk model) author: NIRAS pointOfContact : contact@geus.dk boundingBox: BBOX modelingSoftwareToolName: Geoscene 3D … Model discovery Geologic (modelled) feature (e.g. structure based on lithology) Input model used Grid resolution & unit Parameter Nugget in the interpolation, parameters used to generate the mesh Model description for exchange Copyright © 2017 Open Geospatial Consortium
