Datum Ensemble^c # Classes

URI https://w3id.org/geosrs/datum/DatumEnsemble

Description

URI	`https://w3id.org/geosrs/datum/DatumEnsemble`
Description	A collection of two or more datums (or if geodetic or vertical, a collection of two or more reference frames) that are realizations of one Conventional Reference System and which for all but the highest accuracy requirements may be considered to be insignificantly different from each other. Note: Within the datum ensemble every frame or datum is constrained to be a realization of the same reference system. Cf. ISO 19111:2019 Geographic information — Referencing by coordinates.

Defining Parameter^c # Classes

URI	`https://w3id.org/geosrs/datum/DefiningParameter`
Description	Parameter value, an ordered sequence of values, or a reference to a file of parameter values that define a paramtric datum. Cf. ISO 19111:2019 Geographic information — Referencing by coordinates.

Dynamic Geodetic Reference Frame^c # Classes

URI	`https://w3id.org/geosrs/datum/DynamicGeodeticReferenceFrame`
Description	Geodetic reference frame in which some of the parameters describe time evolution of defining station coordinatesExample: defining station coordinates having linear velocities to account for crustal motion.
Super-classes	geosrs:GeodeticDatum^c

Dynamic Vertical Datum^c # Classes

URI	`https://w3id.org/geosrs/datum/DynamicVerticalDatum`
Description	Vertical reference frame in which some of the defining parameters have time dependencyExample: Defining station heights have velocity to account for post-glacial isostatic rebound motion. Cf. ISO 19111:2019 Geographic information — Referencing by coordinates.
Super-classes	geosrs:VerticalDatum^c

Engineering Datum^c # Classes

URI	`https://w3id.org/geosrs/datum/EngineeringDatum`
Description	Definition of the origin and orientation of an engineering coordinate reference systemNote: The origin can be fixed with respect to the Earth (such as a defined point at a construction site), or be a defined point on a moving vehicle (such as on a ship or satellite), or a defined point of an image. Cf. ISO 19111:2019 Geographic information — Referencing by coordinates.
Super-classes	geosrs:Datum^c

Parametric Datum^c # Classes

URI	`https://w3id.org/geosrs/datum/ParametricDatum`
Description	Textual description and/or a set of parameters identifying a particular reference surface used as the origin of a parametric coordinate system, including its position with respect to the Earth. Cf. ISO 19111:2019 Geographic information — Referencing by coordinates.
Super-classes	geosrs:Datum^c

Temporal Datum^c # Classes

URI	`https://w3id.org/geosrs/datum/TemporalDatum`
Description	Definition of the relationship of a temporal coordinate system to an objectNote: The object is normally time on the Earth. Cf. ISO 19111:2019 Geographic information — Referencing by coordinates.
Super-classes	geosrs:Datum^c

Triaxial Ellipsoid^c # Classes

URI	`https://w3id.org/geosrs/datum/TriaxialEllipsoid`
Description	Surface of an analytic ellipsoid defined by three axes of different length. Also referred as scalene ellipsoid.

URI	`https://w3id.org/geosrs/datum/primeMeridian`
Description	The prime meridian used by a geodetic datum. Cf. ISO 19111:2007:2007-07, table 34, association role primeMeridian.
Domain(s)	geosrs:Datum^c
Range(s)	geosrs:PrimeMeridian^c

URI	`https://w3id.org/geosrs/datum/inverseFlattening`
Description	Indicates the inverse flattening value of an ellipsoid, expressed as a number or a ratio (percentage rate, parts per million, etc.). Cf. ISO 19111:2007:2007-07, table 37, attribute inverse flattening
Domain(s)	geosrs:Ellipsoid^c
