摘要:

AbstractMartin Hotine was many things to many men and women; to the Army he directed the British surveying effort during World War II; to photogrammetrists he wrote one of the first great English texts on the subject; to field surveyors he was the architect of the East African section of the Arc of the 30th Meridian and of the re-triangulation of Great Britain; to mathematical geodesists he was the writer of vital papers on three-dimensional geodesy; whilst to countless others around the world he was the instigator, and for many years the first director of the Directorate of Overseas Surveys. To me personally he was a tough manager, wholly dedicated to the job which had to be done, hard, and single-minded in his pursuit of knowledge and excellence. He said to this conference in 1951,‘I still study higher mathematics on long and tedious journeys by air. In fact, the worse the conditions, the more there is to be said for some concentrated means of taking one's mind off them.’Yet notwithstanding all of this, he remained an intensely human man, and to me, a man capable of much compassion and personal kindness. He gave some of the best advice that I have heard:‘The ability of a good leader’, he used to say,‘is the ability to let subordinates make mistakes’, although brevity, in this case, concealed some important reservations.

摘要:

AbstractOf recent years at least three manufacturers of surveying equipment have developed the use of theodolite intersections for industrial uses. They have developed highly sophisticated instruments and portable data-capture systems that are capable of real-time analysis and presentation of data to accuracies of 20μm, depending on geometry and other conditions. The three systems referred to are the TOK of Zeiss, Oberkochen, the RMS of Wild of Heerbrugg, and the ECDS of Kern of Aarau. It is not a commercial gimmick that these new titles have been conjured up; the systems are very different, in respect of speed, convenience and accuracy, from their essentially simple ancestors. It is the purpose of this paper to illustrate and explain just how sophisticated these systems are, and to hint at their potential.

摘要:

AbstractThe author raised the nature of the problem presented by the geometry and philosophy of quadrature in a letter to the Editor (Survey Review28, 221, pp. 372–373).This paper examines the background to the proven impossibility of the Quadrature of the Circle, offers methods for apparently achieving that quadrature, and poses questions concerning the validity of any proof of impossibility which is based upon a demonstration of the incommensurability ofπ.

摘要:

AbstractTwo methods for directly computing the geodetic coordinates of a point, employing a surveyed vertical angle, azimuth and slant range a known station point, are illustrated.This calculation in field survey operations is made possible by Integrated Electronic Theodolites
