orientation determination method concepts
CGI Orientation Determination Method
this vocabulary
Orientation value is specified using a calculated average of a collection of related orientations (computer generalization).
calculated average orientation
this vocabulary
Orientation of a geologic structure estimated based on inspection or measurements on an air photograph.
estimate from air photo
this vocabulary
Orientation of a geologic structure based on observation from a distance great enough to preclude direct inspection of the structure to determine orientation.
estimate from distance
this vocabulary
Orientation of surface or line is measured on an outcrop of that surface or line directly, e.g. by measuring a particular bedding surface, a 3-D exposure of a fold hinge, a particular stretched mineral grain in a foliation surface.
measure on outcrop
this vocabulary
use value qualifier to specify the kind of nil.
method unknown
this vocabulary
Orientation determined based on measurements from aerial photography or satellite imagery (in conjunction with an elevation model.
photogeologic determination
this vocabulary
Orientation measured using compass or other instrument directly on or at an outcrop of the structure.
standard on site measure
this vocabulary
Orientation determined by fitting a plane to three or more points located on the geologic surface of interest.
three point determination
this vocabulary
Orientation of a surface is measured by visually averaging across one or more outcrops in a small area--e.g. approximating dip by looking down strike of beds, approximating strike by outcrop trace of one or more beds.
visual surface estimation on outcrop

CGI Determination Method for Orientation Term Vocabulary
201211
This file contains the CGI Determination methods vocabulary. Methods of measuring orientation of geometrical features in rock bodies. Describes the way the dip value was determined e.g. measured, inferred from dip slope etc.
2012-11-24 SMR Update to 201211 version; add collection entity, check all pref labels are lower case, remove owl:NamedIndividual and Owl:Thing rdf:types.
2010-02-08. SMR Clean up namespace declarations so concept URI's follow CGI URN scheme; concepts have URN, are not document fragments.
2010 11 27 SMR convert identifiers from URN to http URI according to CGI URI scheme.
2012-02-07 SMR update URI to replace numeric final token with English-language string as in original URN scheme.
2009-07-14. Generate SKOS encoding of vocabulary from Excel spreadsheet.
2012-02-27 SMR add skos:exactMatch triples to map URIs for concepts in this vocabulary to number-token URIs in 201012 version of same concepts.
2010-02-12 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.
