A MODEL FOR A FOUR-DIMENSIONAL REGIONAL GEODETIC REFERENCE DATUM

Survey Review, 1997
AbstractA model for the establishment of a four-dimensional regional geodetic reference datum is presented. Starting from the three-dimensional integrated geodetic network model, formulations for the establishment of a four-dimensional regional datum are developed.

Review of the Classical Methods for the Determination of Geodetic Datums

International Astronomical Union Colloquium, 1975
In conventional geodetic systems, locations of points on the surface of the Earth may be defined either by means of natural (astronomic) or geometric gepdetic cooprdinates. The natural coordinates, the astronomic latitude (Φ), longitude (λ), and the orthometric (mean sea level) height (H), being gravity dependent, are conventionally referenced, to the ...

Reference Systems, Reference Frames, and the Geodetic Datum

2008
Unambiguous reference systems are a fundamental requirement for accurate and reliable geodetic products. The definition of the reference system, the realization by a reference frame, and the allocation of the geodetic datum have to be strictly coherent.
