About the Borehole Interoperability Experiment

Following the birth of the OGC GeoScience DWG in September 2017, an Interoperability Experiment about Borehole data was launched.

Starting in March 2018, during the Orleans OGC TC, the GeoScience DWG work on how connect several existing borehole definitions.

More details about this initiative can be found on the Borehole IE Github.

Engineering report

This document describes a conceptual model, logical model, and GML/XML encoding schema for the exchange of borehole related data and especially all the elements that are positioned along a borehole trajectory. In addition, this document provides GML/XML encoding instances documents for guidance

Sampling Boreholes

Before we can provide data for various tests to be performed on boreholes, we must determine what spatial features must be defined to serve as features-of-interest for these tests. We start by differentiating between the Hole (the absence) and the Core in their entirety. Both the Hole and the Core can then be subdivided, either as Points or as Segments. Dedicated featureTypes have been created for all six of these variants, as illustrated in the diagram below.

As linear referencing is a key function for the provision of borehole observation, it was then proposed to connect ISO19148 (linear referencing) and ISO 19156 (observations, measurements and samples).
