ABSTRACT
The use of surveying control networks in civil engineering has become widely accepted over the last twenty years or so, particularly since the advent of modern computers which have the speed and storage capabilities required to make the rigorous calculation of such networks a realistic proposition in the construction environment. Nowadays, a comprehensive survey network design and analysis can be carried out with little effort on a desktop personal computer, and even networks of the size of the national primary triangulation of Great Britain can be computed rigorously on such a machine.
