A standardized vertical datum is required for global geodetic consistency.
A standardized vertical datum is required to achieve consistency across global geodetic frameworks, replacing fragmented local sea surface level systems with a unified reference frame.
The claim asserts that a standardized vertical datum is required for global geodetic consistency. This is a specific, empirical, and contestable (now standard) geodetic principle. Papers [0] and [5] directly support this by detailing international initiatives (such as those by GGOS) to unify height systems worldwide and resolve discrepancies among local vertical datums. No papers refute this claim.

Fairchild et al. (2012) highlight that the Global Geodetic Observing System promotes the standardisation of height systems worldwide to provide a reliable reference frame for consistent global geodetic and gravity field modelling.

Grzempowski et al. (2015) demonstrate the necessity and methodology of connecting local vertical datums to a global vertical datum to resolve substantial differences in regional height measurements.
