List of all enumerations of this type. Must be declared before any enum declaration. -
OTHER_SURFACE
@UML(identifier="other surface", obligation=CONDITIONAL, specification=ISO_19111) public static final VerticalDatumType OTHER_SURFACEIn some cases, e.g. oil exploration and production, a geological feature, such as the top or bottom of a geologically identifiable and meaningful subsurface layer, is used as a vertical datum. Other variations to the above three vertical datum types may exist and are all included in this type. -
GEOIDAL
@UML(identifier="geoidal", obligation=CONDITIONAL, specification=ISO_19111) public static final VerticalDatumType GEOIDALThe zero value of the associated vertical coordinate system axis is defined to approximate a constant potential surface, usually the geoid. Such a reference surface is usually determined by a national or scientific authority, and is then a well-known, named datum. -
DEPTH
@UML(identifier="depth", obligation=CONDITIONAL, specification=ISO_19111) public static final VerticalDatumType DEPTHThe zero point of the vertical axis is defined by a surface that has meaning for the purpose which the associated vertical measurements are used for. For hydrographic charts, this is often a predicted nominal sea surface (i.e., without waves or other wind and current effects) that occurs at low tide. Depths are measured in the direction perpendicular (approximately) to the actual equipotential surfaces of the earth's gravity field, using such procedures as echo-sounding. -
BAROMETRIC
@UML(identifier="barometric", obligation=CONDITIONAL, specification=ISO_19111) public static final VerticalDatumType BAROMETRICAtmospheric pressure is the basis for the definition of the origin of the associated vertical coordinate system axis. These are approximations of orthometric heights obtained with the help of a barometer or a barometric altimeter. These values are usually expressed in one of the following units: meters, feet, millibars (used to measure pressure levels), or theta value (units used to measure geopotential height).
