AbstractTHE resolutions and pious hopes (væux) passed by the International Union of Geodesy and Geophysics at Edinburgh in September 1936 have just been circulated in a formidable document of 8 pages and XXIX commandments. Of these, two affect the Cape-to-Cairo line particularly and they seem to deserve special study. The first of these, Number III—on systems of Projections—applies the meridional strips of the Transverse Mercator Projection apparently to all maps, topographical as well as cadastral. 相似文献

周、秦时期（公元前841年至公元前206年），由中央王朝于每年八月派遣告使，轻车长驱，采访全国各地物产、民情、风俗、方言，利用“定南”和“计里鼓”进行测量，记录方位、里程，草绘地形，据此编制版籍（绘制地图，编制户籍等），并藏于秘室，以供朝庭了解各地经界、户口、贡赋以及军事要塞等地理信息，从而达到“人主居高堂知天下”的目的。派遣“轩之使”，用记录方式搜集资料，据此绘制地图，是周秦时期独特的地图测绘方式。 相似文献

TERRAIN AND SURFACE MODELLING SYSTEMS: THEORY AND PRACTICE 总被引：1，自引：0，他引：1
This paper presents a critical investigation of those parts of digital mapping that relate to the specific area of terrain modelling systems. In addition, image processing and database systems are considered where they impinge on model creation or later analysis. The theoretical basis for surface mapping systems is described and an attempt is made to determine how best such systems can cover many of the practical requirements of commercial, industrial, and institutional surveyors and researchers. Some proprietary computer terrain modelling systems are mentioned where they have particular features that relate to the theme of the paper. However, most of the examples are derived from Panacea, the terrain modelling software written by the author, although in many cases any major modelling system could have been used. 相似文献

This paper was prepared as supporting documentation for a tutorial given by the authors under Photogrammetric Society auspices. The authors do not make any claims of novelty or innovation but they feel that the information contained in the paper will provide useful study material, especially for practitioners of photogrammetry and surveying. The following topics are covered: functional and stochastic models; the least squares process; statistical testing; optimal design methods; and numerical examples in the design of a horizontal control network and of a close range photogrammetric survey. 相似文献

AbstractGeneral.—The two main causes bringing the Surveyor's work into association with that of the Town-Planning Engineer are development of new areas, arising from industrial, residential, or other necessity for expansion, and the replanning of congested or badly laid out districts in existing towns. The initiative in such schemes may come from a Local Authority, private enterprise, or public representations. 相似文献

AbstractSome time ago during a conversation in the Geographical Section, General Staff, the question of the ages of both Stonehenge and Woodhenge cropped up. As I was at that time stationed at Larkhill Camp, within easy reach of both, it was suggested that I might arrange to observe the azimuths of the axis lines of these two circles, in the hope that such information might be useful in determining which was really the older. This was done, but I regret that pressure of work has meant such a long delay before the resul ts have been made available. 相似文献

AbstractMr. Surveyor A walked into the Club, his first visit after a four-months' field season. He entered the lounge, sank into one of the deep luxurious leather arm-chairs and called for his“sundowner“. In a little while he was joined by several other Government officers, glad to see him after his long absence and eager to hear of his bush experiences and to cap them with stories of their own. 相似文献

AbstractNot long ago a very energetic and able soldier-surveyor said to me, “Why do people indulge in all this hero worship? Our forerunners in the Survey were not so remarkable”. Perhaps, on the few occasions when any of us do write Survey history, distance and loyalty add enchantment to the memories. But there is little harm in that. Besides some, at least, were great men. It is not perhaps of much value to our present work to read how Captain Drummond invented the limelight, in order to get his connexions across the Irish Sea. It does not help us much, although it is very interesting, to know how the Ordnance Survey stumbled on photozincography just at the same time as an Australian in Sydney. On the other hand it is of great importance to know just what standards Clarke did gather together for his great series of comparisons. It is of importance to know how the need arose for this scale or that, from the town plans to the I/M, for the same needs still exist. It is sadder but even more important to know how, entrusted with a magnificent field of action, the Survey gave up this item or that to the great inconvenience of the public. Survey history gives a yard-stick by which to assess the value, the authenticity and the precision of such measurement or topography as still underlies our work. It encourages us by showing what obstacles lcan be overcome, and it also teaches us to avoid the dangers, delays or mistakes we may, all unwittingly, repeat. The last are many indeed. Ordnance Survey history is full of warnings of that sort, for “the evil that men do lives after them; the good is oft interred with their bones”. 相似文献

基于ArcGIS与ArcObjects的线性参考系统的建立与应用 总被引：2，自引：0，他引：2
公路,铁路,河流等线性物体通常用沿线路的相对距离来确定线路上点或线的位置,而线性物体在地理信息系统当中一般用二维坐标系统来模拟,用常规的方法根据相对位置计算位置点的x、y坐标有一定的误差.本文重点介绍了线性参考系统的概念,并提出了基于ArcGIS的线性参考系统的建立与基于ArcObjects的线性参考系统的开发应用相结合的解决方法. 相似文献
