A Quaternion-based Geodetic Datum Transformation Algorithm

Journal of Geodesy, 2006
This paper briefly introduces quaternions to represent rotation parameters and then derives the formulae to compute quaternion, translation and scale parameters in the Bursa–Wolf geodetic datum transformation model from two sets of co-located 3D coordinates.

Positioning of Horizontal Geodetic Datums

The Canadian Surveyor, 1974
This paper treats the classical problem of positioning horizontal geodetic datums. By ‘classical problem’ we mean the problem we face when dealing with the usual horizontal control networks, as opposed to some of the more modern ideas, such as the use of geocentric coordinates, or the ideas of Hotine [1959, 1969].

Geodetic Datum and Geodetic Control Networks

2014
To measure terrain, surface features, position coordinates, heights, and gravity values at points on the Earth’s surface, there need to be corresponding reference points or surfaces (also known as datum points or surfaces), namely geodetic datums, to which surveying and mapping results are referred. Geodetic datums consist chiefly of coordinate datums (

Horizontal and Vertical Geodetic Datums

1989
In conventional geodetic systems, locations of points on the surface of the earth may be defined either by means of natural (astronomic) or geometric (geodetic) coordinates. 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 ...

Geodetic Datums in Canada

The Canadian Surveyor, 1973
Because of 1) the appreciable distortions in the system of coordinates known as the 1927 North American Datum, 2) the definition of oil and gas exploration permit areas and offshore boundaries in t...

Errata/Addendum - Australian Geodetic Datum Technical Manual

Australian Surveyor, 1994
Abstract The Australian Geodetic Datum Technical Manual (Special Publication 10) was produced by the former National Mapping Council of Australia in 1984. Since that time this publication has served as the standard technical reference for the definition of the Australian Geodetic Datum (AGD), the Australian Map Grid (AMG) and the Australian Height ...
