The 13 pages that link to Vertical datum, each with the reason it gives.

• GeodesyRelated: Combining national height systems remains difficult because datums differ and evolve.

• GeoidRelated: A vertical datum specifies how geoid-related heights are realized for mapping and surveying.

• BathymetryRelated: Depth values are meaningful only in relation to a stated reference surface.

• ElevationRelated: It specifies the zero surface from which an elevation is measured.

• Geodetic datumBroader topic: It governs height values, which need not use the horizontal datum’s reference surface.

• Digital elevation modelRelated: The datum determines what zero elevation means in a model.

• Mean sea levelNarrower topic: Mean sea level can serve as the reference surface for elevations, but its definition depends on the chosen datum.

• Tide gaugeNarrower topic: Gauge levels only have meaning when tied to a defined vertical reference.

• Sea levelRelated: Elevation depends on the datum chosen to represent sea level.

• Relative sea levelRelated: Datum choice affects reported coastal elevations and comparisons with sea-level records.

• World Geodetic System 1984Compared with: WGS 84 ellipsoidal height is not interchangeable with elevation above a vertical datum.

• Orthometric heightNarrower topic: A vertical datum specifies the reference framework in which orthometric heights are reported.

• Height above mean sea levelNarrower topic: It specifies the reference surface against which the height is reported.
