The location of the basal surface of a layer (a volume of earthmaterial) that intersects a planar sampling feature. Depending onhow the planar sampling feature is encoded, several line strings maydefine this basal surface.

A polygon that represents the layer volume in the plane of theplanar sampling feature. It is typically a ring polygon whose curvemembers are the layer top intersection, the layer bottomintersection and two edges normally at the lateral extent of theplanar feature. Repeat for each polygon.

Complex Type diggs:PlanarObservationRepresentationType
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
