]> OBOE Spatial This ontology contains terms relating to spatial concepts that are common across OBOE extensions. The terms are derived from the International Standards Organization (ISO) geospatial standards in the 19100 series and from the Geography Markup Language version 3.2.1.

Spatial Feature GML 3.2.1 defines a subclass of AbstractFeature called Observation with a subclass of DirectedObservation. This my conflict with the OBOE concept of Observation. For this reason, these two subclasses are not currently included under SpatialFeature, and this issue needs to be reconciled.

It often defines the nominal location of a station or sampling place.
