| historyNote: | 2010-02-11 Add narrower relationship links by adding skos:narrower link in Protege, defining skos:narrower as inverse of skos:broader, calculating with Pellet reasoner to add inferred axioms, and using 'file/Export inferred axioms as ontology' in Protege. |
| historyNote: | 2010-11-28 SMR Replace URN with http URI according to CGI URI scheme (see https://www.seegrid.csiro.au/wiki/bin/view/CGIModel/PersistentIdentifiersInGeoSciMLServices) |

| prefLabel: | CGI Mapped Feature Observation Method Term Vocabulary |
| definition: | This file contains the CGI Mapped feature observation method vocabulary. These are terms that specify how a MappedFeature instance was mapped. MappedFeature ObservationMethod is essentially a metadata snippet indicating how the spatial extent of the mapped feature was determined, and the basis for association of the geometry with some GeologicFeature specification to define a MappedFeature. Observation method is a convenience property that provides a quick and dirty approach to shortcut use of more comprehensive observation and measurement construct when data are reported using a feature view (as opposed to observation view). |
