Kansas and the Geodetic Datum of North America

Transactions of the Kansas Academy of Science (1903-), 1948
Kansas has the distinction of having within its borders two significant landmarks. One of these is the geographical center of the United States, the other is the Meades Ranch triangulation station or the geodetic datum known as the North American datum of 1927.

Proposed absolute datum for Indian geodetic system

Bulletin Géodésique, 1981
The international ellipsoid, 1924, was locally fitted to the Indian geoid in 1927. An attempt is here made to obtain the initial values for the Indian geodetic datum (I.G.D.) in absolute terms by gravimetric method using the available gravity material. The values obtained independently by the author’s least-squares solution technique, making use of the

The Geodetic Datum in New South Wales

Australian Surveyor, 1984
Abstract In 1969 the National Mapping Council resolved that “all future mapping at all scales” be based on the Australian Map Grid. The AMG is based on the Australian Geodetic Datum 1966, AGD66 which in turn is based on astronomical observations. In consequence of the resolution a massive effort was expended in New South Wales to establish all mapping ...

Review of Problems Associated with Conventional Geodetic Datums

The Canadian Surveyor, 1974
After discussing the parameters needed to define a horizontal geodetic datum, the paper reviews the development of the major geodetic datums. The problem of determining the interrelationships between the various datums is analyzed and current transformation parameters are presented.

DATUM TRANSFORMATION PARAMETERS FOR THE KENYA GEODETIC SYSTEM

Survey Review, 1993
AbstractA summary of the history of geodetic control surveys in Kenya is given and this is related to a geodetic datum. Determination of datum transformation parameters is carried out for the 7-parameter and 3-parameter models using 25 points distributed over the country.

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 ...

DETERMINATION OF A LOCAL GEODETIC DATUM FROM ASTROGEODESY

Survey Review, 1980
Abstract Several methods of choosing a local geodetic datum, based on astrogeodetic deflections of the vertical, are presented. The results of applying these methods to a test network covering about 200 000 square kilometres in western New South Wales, containing sufficient astronomical stations for reliable astrogeodetic levelling, are computed and ...

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.
