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).

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

Quality Control in Geodetic Networks
1985Generally one can consider the “quality of a network design” to be made up of three factors: Economy, Precision and Reliability. Economy then expresses the costs of observation, transport, monumentation, etc.; Precision as expressed by the a posteriori covariance matrix of the coordinates, is the measure of the network’s characteristics in propagating ...

Vertical Geodetic Network of Mexico
2002The objective of this paper is to present the current situation of the National Vertical Geodetic Network of Mexico including operation indicators, data, precision, digital file availability, condition of the National Mareographic System, elevation values referred to the mean sea level, its correlation with values referred to NAVD88 and its application

The Vertical Geodetic Network in Chile
2002The objective of this work is to present the current situation of the vertical geodetic network of Chile that was principally established from 1931 onwards. At this time, the network is composed of a great number of first order points that are distributed on different leveling lines with reference to the mean sea level, and on different highways and ...

Fourier Analysis of Geodetic Networks
1985Life is difficult enough — why not make it easy! We have met this simple idea the first time in a high-school maths course, when we were forced to learn handle logarithms (although hardly anybody got the point): simplify a problem by appropriate transformation.
