Following the ObservationTypology discussed in April. Several specializations of ObservationCollection are proposed: - Serie Observation : A collection of Observations that observed the same property thanks to the same procedure...

NB : the term Fault is prefered in IFC GeoSubgroup but keeping the same definition.

The ShearDisplacementStructure is already defined by CGI IUGS in OGC GeoSciML. DiscreteDiscontinuity is up to us. Both MINnD project and IFC Tunnel GeoSubgroup identified it as a suitable and distinct...

@Alexis-SERIEYS : by defining a relationship between ShearDisplacementStructure and DiscreteContinuity I mean in terms of semantics. In other words, can we say a DiscreteContinuity is a kind of GeologyStructure (a...

The proposal is to have this concept for both the Hydrogeological model #5 and the Geotechnical model #6

Answers to @Didymograptus > Dan some interesting thoughts. I think that counts as a three-beer discussion ;-) +1. Major conceptual models were beer driven :-) > we need to understand...

OGC GeoscienceDWG had a Borehole IE in 2019. The report can be found here : https://github.com/opengeospatial/boreholeie/tree/master/er _This document describes a conceptual model, logical model, and GML/XML encoding schema for the...
