1. Updates on models exchanges in EPOS
104th OGC Technical Committee – GeoScience DWG session
Southampton, United Kingdom

Starting point
Model :
3D, 4D, geophysics…
Model discovery/description
This is not metadata in the ISO 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 !

4. 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 :
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

Work done
EPOS ModelView
SimpleFeature specification (SF-1)
Ex instance
Partners currently implementing it (then will be harvested)
Conceptual model to support national flows
Roughly started between BRGM, GFZ, László SŐRÉS (MFGI)

7. EPOS – ‘Model’ conceptual approch
Mainly based on O&M
Same philosophy as INSPIRE:GE:GeophysicsExtension
