摘要:

AbstractIt seemed to me that this short paper could usefully be confined to a consideration of some aspects of the system of registration of title to land which now applies in England and Wales and in this way it might prove to be helpful to land surveyors not over-familiar with the registration procedures adopted in this country. I believe the references made to the definition of boundaries and to some branches of the law relating to land will be of special interest to the profession. There has been no attempt to discuss the alleged superiority of one particular system of registration over that of another, a matter which can faithfully be relied upon to provoke a near riot at any conference of Commonwealth surveyors. Instead, the paper has been restricted to a brief look at the English system, if I may call it that, and I hope that its contents will be found to be informative and constructive.

摘要:

AbstractThe theory required to obtain the error ellipses of network stations without using the actual values of the observations forming the network is given. The importance of this concept in the optimisation of geodetic networks is pointed out by means of an example.

摘要:

AbstractThis article summarises three former papers [1], [2], [3], the first of which set out for the first time the fundamental principles behind the design of road curvature, and the two later ones described an extensive series of recordings of the motion of cars on curves. From these latter it was concluded that the then current theory proposed for the design of transition curves was fallacious. A restatement is needed because curvature is still being designed on the obsolete theory, at some danger to traffic.

摘要:

AbstractA party of surveyors en route for Fort Augustus at the south-western end of Loch Ness on the Caledonian Canal in Scotland would not cause many eye brows to be raised. But when that same party requires two dozen table tennis balls one might wonder if they intended to enter for the table tennis championships or maybe whether they had found some intriguing way to capture the Loch Ness monster. The answer however is much less romantic but infinitely more practical than tangling with the kelpies of the dark waters of the Highlands; the table tennis balls were required for targets in a geodetic triangulation scheme. The triangulation was part of a study being conducted by geologists into crustal movements in the Great Glen fault which runs in a north-east, south-west direction across the Highlands of Scotland.

摘要:

AbstractIt has been said that any discussion of the relative merits of one particular system of land registration over another can be faithfully relied upon to provoke a near riot at any conference of Commonwealth surveyors. The ownership of land and the rights appertaining thereto are emotional topics in all corners of the Earth and not surprisingly perhaps this emotion extends to those responsible for describing the parcels of land into which the Earth is divided. The reasons why the surveyor develops such feelings on these matters may lie deep in the subconscious but at a superficial level they are undoubtedly influenced by a general ignorance of the alternative methods for describing and recording parcels of land and the reasons why and how any other systems tick. Each system has evolved in its own setting over a period of time and has been adapted to meet local requirements. This is not to say that it has necessarily evolved in the most appropriate way or that radical changes might not be beneficial. It is however true to say that the biggest bottleneck in the whole registration process lies in the surveying and mapping of properties and that there are parts of the world where the cost of survey is greater than the value of the land. Thus a would-be mortgagee who wishes to register his land as collateral, must either payor be subsidised by an amount greater than he can borrow. It is with problems like this in mind that a resolution was passed at the last Conference of Commonwealth Survey Officers recommending that a study be instituted leading to a publication setting out the techniques used for, and the costs and efficiency of, marking, surveying and recording land parcels in the Commonwealth. Work on this has already begun and it is hoped that something positive will be available by the next Conference.

AbstractIt was with interest that we awaited the arrival of CP1 002, one of the first production batch models of the new photogrammetric plotter designed by Professor Thompson of University College London. This instrument, which attracted a great deal of attention when it was first exhibited at the Conference of Commonwealth Survey Officers in August 1971, is manufactured byCartographic Engineering Limitedof Salisbury and marketed by A. Clarkson&Co. Limited of London. It sells for just over£3,000.

摘要:

AbstractNew electronic calculating machines are appearing on the market so rapidly that it is difficult to define criteria with which to assess them. The Hewlett-Packard 35 reviewed in the last issue of this journal(1)set a new standard in size and range of functions offered; this new machine, the Casio fx—l (fx one) is larger (240×315×77.5 mm, 2.3 kg) and operates from mains only but offers a slightly different range of functions and operating features. It should not be necessary to repeat the introductory remarks made in the review of the HP35 except to say that the Casio is able to cope with all the operations of a mechanical machine to an accuracy of 11 significant figures.
