Vocabulary

This scheme contains concepts used to specify the approach to acquiring the collection of attributes to describe an individual feature instance, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. Observation method is a convienence property that provides a quick approach to shortcut use of more comprehensive observation and measurement construct when data are reported using a feature view (as opposed to observation view). By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme.
