Ontologies and data model of RESQML v2.2 format for operational and interoperable transfers of boreholes data from a 3D geomodeller to GIS and CAD/BIM softwares

 abstract = { EGIS is engaged in a BIM and GIS approach for all these civil engineering projects. The RESQML V2.2 format was chosen as no IFC components are designed to transfer geological and geotechnical 3D models. At the previous Ring Meeting, we communicated on our solution for transferring 3D geomodels modeled with GDM-MultiLayer and their boreholes data to the Autodesk softwares suite (Léonard, 2019). This year, EGIS decided to add to these tools a RESQML v2.2 file import module for ArcGIS Pro. The development of the import part concerning the transfer of boreholes data into GIS files is the subject of Priscillia's internship. In this communication, we detail the ontologies and the data model of the RESQML v2.2 format and we give valuable methodological information allowing developers to produce RESQML files of good quality and which offer the possibility of transferring several possible interpretations of boreholes logs. Indeed, if the first interpretation of the boreholes is based on the lithological description of the drilling log, the geologist who produces the 3D models must reinterpret these data in order to build stratigraphic or geological models consistent with the geological map. For the purposes of the civil engineering project, the geologist must also build a geotechnical model, which takes into account mechanical criteria. The lithological pile of the geotechnical model is different from that used for the geological model. A hydrological interpretation of the geomodel can also be made and will be associated with the hydrogeological interpretation of the boreholes. In this communication, we will report the first steps and the results of our developments on RESQML-GIS, our new module for ArcGIS Pro (ESRI). We will also show the results of an experiment of transferring a simple geomodel and their drilling data between GoCAD-SKUA and Autodesk Civil 3D. This experiment shows the necessity to follow a good methodology for exporting RESQML files and the importance to distinguish the type of interpretation of the geomodels and the boreholes data.   EGIS is engaged in a BIM and GIS approach for all these civil engineering projects.
