Type definition

This enumeration defines the different predefined types of geoscience observation types that can specify an IfcGeoScienceObservation.

Enumeration definition

Constant	Description
INSITUTESTRESULT	Result from a test carried out on site directly in place, e.g. in a borehole, a gallery or from the surface.
LABTESTRESULT	Result from test on a rock/soil (geologic) or fluid specimen carried out in a laboratory.
BOREHOLELOG	Any kind of observation or measurement result related to intervals or points on the borehole axis.
MAPPEDFEATURE	Distinctly mapped structures that have been observed on MappedZones such as lineations, fold axes, discontinuity surfaces etc.
LOCALINFORMATION	Other observations made locally (e.g. at a point) such as discontinuities, water inflow, weathering, rockburst etc.
GEOPHYSICALSURVEYRESULT	A systematic collection of geophysical data that was gathered either at or near the ground surface or by using boreholes and measuring the whole volume in between (crosshole).
USERDEFINED	User-defined type.
NOTDEFINED	Undefined type.
