Advanced:
specification of the relationship of a coordinate system to an object, thus creating a coordinate reference system<br/>Note: For geodetic and vertical coordinate reference systems, it relates a coordinate system to the Earth. With other types of coordinate reference systems, the datum may relate the coordinate system to another physical or virtual object. A datum uses a parameter or set of parameters that determine the location of the origin of the coordinate reference system. Each datum subtype can be associated with only specific types of coordinate reference systems.<br/>

Public CharacterString
  anchorDefinition
Details:
Notes: description, possibly including coordinates of an identified point or points, of the relationship used to anchor a coordinate system to the Earth or alternate object <br/>Note: For modern geodetic reference frames the anchor may be a set of station coordinates; if the reference frame is dynamic it will also include coordinate velocities. For a traditional geodetic datum, the anchor may be a point known as the fundamental point, which is traditionally the point where the relationship between geoid and ellipsoid is defined, together with a direction from that point.<br/>- For a vertical reference frame the anchor may be the zero level at one or more defined locations or a conventionally defined surface. <br/>- For an engineering datum, the anchor may be an identified physical point with the orientation defined relative to the object.<br/>
