Guy Bomford Brigadier Guy Bomford (28 June 1899 – 10 February 1996; also published as G. Bomford or simply G.B.) was a British geodesist who, at various times in his career, worked for both the Survey of India and the Corps of Royal Engineers. He is best ...

Content

''Geodesy'' is formatted as a textbook on the topic of geodesy, with particular emphasis on its applications to
triangulation In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to the point from known points. Applications In surveying Specifically in surveying, triangulation involves only angle m ...
. For content on applied geodesy, it is assumed the reader can use a
theodolite A theodolite () is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and ...
and a micrometer. The book also discusses the overlap between geodesy and the study of
geophysics Geophysics () is a subject of natural science concerned with the physical processes and Physical property, properties of Earth and its surrounding space environment, and the use of quantitative methods for their analysis. Geophysicists conduct i ...
. Due to a limit on space, the first edition intentionally leaves out information on the
history of geodesy The history of geodesy ( /dʒiːˈɒdɪsi/) began during antiquity and ultimately blossomed during the Age of Enlightenment. Many early conceptions of the Earth held it to be flat, with the heavens being a physical dome spanning over it. Early ...
, only including it when essential to understanding the current practices. In the same edition's acknowledgements, J. de Graaff-Hunter was noted for often discussing the book's content with Bomford. Excluding appendices and following sections, the first edition is 391 pages long. The book's second edition included information on the tellurometer, which had been introduced after the first edition's publication, and its relevance to triangulation. This edition also covered more details on how the development of
electronic computers A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', wh ...
impacted the field of geodesy. These updates brought the book more up to date in regards to technology and techniques developed since the first edition's publication. The book's third edition was a major rewrite of the second edition, as technology including electromagnetic distance measurement, computers, and

Esson's review, published in '' Geological Journal'', which complained the book explained processes but not their importance—the review described the book as "all technique but no passion." However, Esson went on to evaluate the book as "an invaluable reference" and "an unrivalled monolith."
