Borehole

What is a Borehole?

A Borehole is the generalized term for any narrow shaft drilled in the ground, either vertically, horizontally, or inclined.

Realizations

Data model	Concept name	Definition
OGC GeoSciML	Borehole	A Borehole is the generalized term for any narrow shaft drilled in the ground, either vertically, horizontally, or inclined.
IFC 4.4+	Borehole	Same as OGC GeoSciML
AGS	LOCA	AGS LOCA includes exploratory holes of any type, e.g. borehole, trial pits, CPT
DIGGS	Borehole	A sampling feature feature that is a deep, narrow excavation made by drilling and/or extraction of earth material. Boreholes are constructed typically for the purpose of investigating subsurface geologic or geotechnical conditions, exploring for water or oil, for installation of wells or other downhole monitoring installations.
DIGGS	Sounding	A sampling feature that is created by a measurement or construction activity through insertion of a probe or tool into the ground.

FAQ

What about Trial Pit?

Despite a lot of similarities with borehole, the Trial Pit is proposed as a different concept.

See https://github.com/opengeospatial/Geotech/wiki/TrialPit for its description.

What about Borehole core?

A borehole core is considered as a MaterialSample.

See https://github.com/opengeospatial/Geotech/wiki/MaterialSample for its description.

What about Borehole Logs and Observations?

All observations, measurements and test descriptions from a Borehole are considered as Observations.

See https://github.com/opengeospatial/Geotech/wiki/Observation for their description.
