The accuracy of Australia's geodetic network
Journal of Spatial Science, 2005Australia's network of well‐established geodetic survey marks is the essential basis for the country's spatial data infrastructure. Until recently the precision of these positions was only really understood in a relative sense and was generally represented by an Order (1st order, 2nd order, etc).

On continuous theory for geodetic networks
2005Geodetic levelling networks and networks with distance measurements are analysed in order to elucidate their special features. This analysis naturally leads one to look for continuous analogons of these networks. By means of tools known from the method of finite elements we derive the corresponding Green's functions for various boundary value problems.

The Greenland Geodetic Network (GNET)
2020<p>The Greenland Geodetic Network (GNET) consists of 58 global navigation satellite systems (GNSS) installed on the bedrock around the perimeter of the island. Much of the network was installed between 2007 and 2009, providing a long time series of GNSS data for much of Greenland.

The Canadian Surveyor, 1974
Geodetic networks in Canada are concentrated in the southern populated regions and tend to reflect immediate demands. A long-range plan has now been undertaken to establish and maintain horizontal and vertical control frameworks that can adequately meet needs in any part of the country. A shorter term phase of this plan is the new North American Datum

Combined Adjustment of National Astro-Geodetic Network and National GPS2000 Geodetic Network
2008The combined adjustment between the National Astro-Geodetic Network and the National GPS2000 Geodetic network in China is described. In this paper, measurements of astro-geodetic network had been taken for nearly 60 years from early 1920’ to 1980’. Some astro-geodetic points may have moved during such a long time period, so coordinate analysis for ...

The Canadian Surveyor, 1974
The computation of geodetic networks has been carried out by establishing a correspondence between points of the actual physical surface of the earth and points of the reference ellipsoid and by treating elevations separately. This approach does not seem to be tenable any longer in view of the modern needs of space geodesy.

Polar Record, 1971
To know the exact size and shape of the earth has long been a goal of scientists. Man's attempts to locate himself and to determine the configuration of his planet date from at least the time of Eratosthenes, about 200 BC. He observed that on a particular day in mid summer the sun shone directly down a well in Syene, Egypt (thus the zenith angle=0 ...

A new approach to geodetic networks
Studia Geophysica et Geodaetica, 1984The linearized model of a geodetic network, expressed by the relationv=Ah−I, does not generally satisfy the following conditions: C1. The results of measurements are mutually independent. C2. The balance of the corrections is given in terms of the corrections of measurements and configuration only. C3.

The Optimum Design of Geodetic Networks
The Canadian Surveyor, 1965For a geodetic network, the least squares adjustment gives the best possible solution and an indication of the quality of that solution. On this basis, a computer program is being developed at the University of Michigan to determine the best and most economic configuration networks and the accuracies required in measuring.

Bulletin géodésique, 1967
The great San Francisco earthquake of April 18, 1906 , presented an opportunity for geodesists to assist in the study of earthquake mechanisms. It was a rather elementary matter for residents of the area to report displacements of 3 to 5 meters by merely noting the offsets in fence lines, orchard rows, or other manaligned features. Geodetic surveys had
