AbstractThe exhibition of cadastral maps and of land-registry and land-revenue records arranged at the Science Museum in July 1931 in connexion with the second Conference of Empire Surveyors was, we believe, the first of its kind to be held anywhere. The idea took shape slowly and required more preliminary discussion and preparation than had been anticipated. This caused the issue of notices explaining the exact nature of the exhibition to be delayed, and therefore handicapped participation, particularly by countries at a distance from England. The response made under these difficult conditions was remarkable. A most excellent and instructive series of exhibits was received from the responsible public services in the United Kingdom, all the Dominions, five Indian provinces, eleven Colonies and Protectorates, three Mandated Territories and six Foreign Countries. The resulting exhibition was so much appreciated that the desire was expressed by the Conference that the exhibits should be retained in some convenient centre in London as the nucleus of a permanent collection for reference and comparative study. 相似文献

AbstractWe regret that, owing to illness and the pressure of other demands on them in the same field, it has been necessary to interrupt the publication of the papers on cadastral subjects which Sir Ernest Dowson and Mr. Sheppard are contributing to the Review. We hope, however, to resume this valuable and interesting series in the January 1947 issue.— ED., E.S.R. 相似文献

AbstractAlthough the title of this paper may appear to some to refer to a rather humdrum subject which hardly deserves much serious thought or consideration, it is the writer's experience that the vital necessity for keeping clear records of survey work in a permanent form in which they can easily be referred to at any future time is not always sufficiently appreciated by those whose duties do not involve constant or frequent reference to the records of old work. Accordingly, the following notes and suggestions, which are based on practical experience, may be of service in drawing attention to a matter which is really of great practical importance. 相似文献

基于全站仪的圆形建筑物倾斜观测的方法和精度 总被引:2,自引:0,他引:2
随着建筑物的不断增高、增大,其稳定性和可靠性成为人们关注的焦点.其中建筑物的倾斜度是衡量施工技术质量的重要指标之一.而传统的观测方法如经纬仪测小角法、经纬仪投点法,由于受仪器精度和观测条件的限制,观测精度较低.拓普康全站仪独具推出的圆柱偏心测量功能为快速、准确测定圆形建筑物的倾斜量开辟了一条新途径,本文阐述了基于全站仪的圆形建筑物倾斜观测的原理和方法,并对其精度进行分析. 相似文献

The article discusses a general classification system applicable to digital ground models (D.G.M.) as used in highway design. Examples of the various categories are given, together with details of some advantages and disadvantages. The place of the D.G.M. in the highway design system is described in conjunction with traditional methods. The relationship between accuracy, density and economy of D.G.M. systems is examined. Finally an experiment is described which investigates the accuracy of various D.G.M. systems; it is being conducted by the Transport and Road Research Laboratory. 相似文献
