COMMONWEALTH SURVEY OFFICERS CONFERENCE, 1951

Abstract

As already noted in the last instalment of this report, the whole of Monday, 16th July, was devoted to all-day visits to (i) a surveying ship of the Royal Navy, or (ii) the Royal Observatory at Hurstmonceaux Castle, or (iii) the School of Military Survey at Newbury, Berks, delegates being divided into three groups with one group going on each visit.     

THE COMMONWEALTH SURVEY OFFICERS CONFERENCE, 1955

Abstract

The sixth Conference of Commonwealth Survey Officers, which was held between Monday, 15th August, and Friday, 26th August, 1955, differed from all previous conferences of the same kind in that it was held at Cambridge instead of London. The advantage of meeting in Cambridge was that delegates could be accommodated in some of the Colleges so that those who were interested in the same subject were able to foregather in the evenings for private and informal discussions after the officialmeetings had concluded.     

CONFERENCE OF EMPIRE SURVEY OFFICERS, 1935

Abstract

The third Empire Surveyors' Conference has come and gone. It fully bore out the promise of its predecessors and was most interesting and instructive for all those who attended, as it will certainly prove to be for readers of the forthcoming Report. This year's gathering was noteworthy particularly for the better representation of the self-governing Dominions; Messrs. Peters, Percival, and Whittingdale, representing respectively Canada, Australia, and South Africa, formed a worthy trio to hold the Dominion bridge, while there were present also, besides the colonial delegates, Brigadier Couchman, the Surveyor-General of India, and a strong contingent from the Mother Country.     

THE SCHOOL OF MILITARY SURVEY AND ITS COURSES FOR COMMONWEALTH SURVEYORS

Abstract

On the first of January 1949 the Survey Training Centre of the Royal Engineers became the School of Military Survey. In the previous two years over fifty Colonial Survey Officers or Probationers came to the Training Centre as students on various courses. Many of these have now taken their places in the Colonial Survey Service. More students may come in the future not only from the Colonies but also from the Dominions, for just as the Military Survey courses are open to the military officers of the Dominions so are the Colonial Survey courses open to the survey students from the Dominion Governments. Some information about the School and courses may be of interest to these potential students and to many readers of this Review, and these notes have been written with the intention of providing this information     

SARAWAK LANDS AND SURVEY DEPARTMENT, 1940

Abstract

Financial.-The revenue collection for the year was 440,790.30, consisting of Land revenue 336,422.97 and Mining revenue 104,360.33. The expenditure for the year was 206,476.02, of which only 192.05 was Special. This does not include salaries, amounting to 14,313, of Officers seconded for Food Control. Expenditure was again below normal because of the secondment of staff to other duties.

UGANDA,LAND AND SURVEY DEPARTMENT,ANNUAL REPORT, 1938

Abstract

Among colonial dependencies Uganda is but a small territory; but it is comparatively prosperous and is compact. In such circumstances the integration under one departmental organization of survey and registration and of the administration of the State's responsibilities for lands and mines proves to be a convenient and economical arrangement, which works, in the balance, to the advantage of the survey branch. The Annual Report for 1938 deals with all the activities of a diversely occupied department, which controlled revenue collections of over £56,000, and mineral exports valued at £225,000.     

滑坡遥感调查、监测与评估

滑坡遥感调查包括滑坡识别、基本信息获取和滑坡空间分析等，本文以天台乡滑坡遥感调查中用特征点法确定滑坡边界、影响带及滑坡运动特征及规模为例说明。滑坡遥感监测可分为直接监测和间接监测。由于突发的高速超高速崩塌、滑坡及泥石流活动时间难以预测，滑坡运动的规模相对于遥感地面分辨率较小，获取遥感数据的不连续性及价格昂贵等原因，目前较少应用遥感技术直接监测滑坡活动； 遥感监测滑坡运动引起的环境变化，称为间接滑坡监测，以遥感监测易贡大滑坡引起的易贡湖水面变化及溃坝造成的下游灾害为例说明。滑坡遥感评估指在获取滑坡及其发育环境基本信息的基础上，评估滑坡的稳定性，预测其未来活动性，评估区域滑坡的影响因子和进行区域滑坡危险性评价，文中以天台乡滑坡、千将坪滑坡稳定性评估及三峡库区中前段区域滑坡危险性评价为例说明。     

CADASTRAL AIR SURVEY

Abstract

I Hope Dr Wolff's interesting article will stimulate to action some of those who have not given sufficient attention to air survey as a method of mapping or planning those areas which lend themselves to that method. At the same time, whether so many of us are as conservative as the author appears to think is a matter for doubt, and moreover we do not all look upon air survey as an “innovation”. As Dr Wolff writes from Palestine he might be interested to know that as the second British Officer to take up field survey work in the War in 1915—Major (now Brigadier) Winterbotham being the first—I was one of the earliest in my profession to study, and to assist in the development of, air survey. In 1915 our unit in the 3rd Army was the first to make use of air photographs for the production of a regular series of trench maps. There are consequently few surveyors more interested in the method. I have watched the progress of the science and the work of the Air Survey Committee with continued interest and have used air methods whenever these have been possible or suitable. On my last visit to Paris I tried my hand at plotting with a new instrument at the Service Géographique and was much impressed by the work that was being done.
