Riassunto

This text introduces the concepts and applications behind plane networks. The book presents features on: fundamental material includin linear algebra and differential equations; an examination of tools for analyzing discrete networks; transition from the discrete to the continuous case is described via finite elements; Green's functions; problems and examples; techniques applied to levelling; practical problems that underscore the continuous theory; and others.

Recensione

"This concise book renders an advanced exposition of the theory of error propagation in geodetic networks that are comprised of up to a few hundred nodes... The reviewed book constitutes a timely and valuable contribution to the theory of plane geodetic network analysis and design. An outstanding feature of this book is the extensive use it makes of the nowadays easy availability of sophisticated automatic computing tools.”
