Schema documentation for component diggs:GeoUnitObservation

A soil or rock unit defined primarily by the value, or a range of values, of one or more physical or engineering properties; the criteria that distinguish units depend on the engineering application. The three-dimensional body of a unit, if one is given, is held by the inherited diggs:location property, which admits any diggs:AbstractGeometry, for example a diggs:SurfaceBoundedSolid, diggs:Solid, diggs:MultiSolid or diggs:CompositeSolid.

Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods. This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.

A legacy attribute for AGS trial pit sampling features, where observations of different strata can occur at the same depth in a pit: a reference letter or number whose sole purpose is to link the stratum on the face sketch of the trial pit to the observation.
