盛夏酷暑,闷热难忍,平山一行,引发驼梁山之游。
车在绿岩上行驶,弯弯曲曲的山路转的不知东南西北。下午五时许,在朋友协助下,我们进入了景区,天空虽仍淅淅沥沥的下着雨,但傍晚的驼梁,人声鼎沸,显得异常热闹非凡,宽阔的广场上,一座座豪华宾馆拔地而起,在驼梁脚下添置了无限风光。热情的农家孩儿围拢上来,口若悬河,滔滔不绝的介绍住农家院、食农家饭的独特风味,意在招揽顾客。发家致富,竞也成为驼梁脚下的一道靓丽风景。天渐渐暗淡下来,点点滴滴的雨在冷风的吹拂下打在身上,感觉已不是凉爽,而是有点冷。好心的农家女走来,高撑雨伞,微笑着对我说:“到我家住吧!我家门前有一商店,可以买到衣服,这里的晚上是要穿秋衣秋裤的。 相似文献

埋头干事,善于创新,是一个年轻干部取得成功的不竭动力。新河县国土资源局局长张国新正是这样一位在拼搏中进取,在创新中前进的开拓。1983年8月,他大学毕业后在乡镇锻炼两年,1985年12月调县农业局土地管理股,1987年3月土地管理局成立后,他任地籍管理股和建设用地股股长,1993年11月任副局长,由于工作成绩突出,1995年在全县破格提拔为局长,当时29岁。在他任职的十年里,用一名共产党员的无限忠诚,凭着自己果断的创新意识和实实在在的苦干精神,开创了新河县国土资源管理工作的崭新局面,取得了令人瞩目的成绩,普法教育、地籍管理、执法监察、项目用地、开发储备、行风建设等工作都走在了前列。 相似文献

随着计算机技术的发展,数字地形图的技术已在生产中得以普及。但是在满足GIS建库方面,还有大量工作要做。城市基础地形图库是GIS应用系统的基础,因此,在制作数字地图时,一定要考虑面向GIS应用,而不仅仅是为了纯粹的机助制图。GIS是以实体为单元存储点、线和面之间的联系,在此基础上, 相似文献

标尺误差是精密水准测量的一项重要误差来源。其中由于温度变化而引起因瓦带的长度变化,是使用因瓦标尺带来的误差之一。国内外有关文献曾对此进行过深入的研究。我国过去在精密水准测量时,未测定所用因瓦标尺的综合膨胀系数,故在一等水准网平差中未对观测高差加标尺温度改正。本文主要针对将要开始的精密水准复测,讨论标尺的温度改正问题和我们的试验结果。 相似文献

三角高程法超长距离跨海高程传递实验研究 总被引:2,自引:0,他引:2
针对三角高程法跨海高程传递测量误差的来源问题,该文提出了基于三角高程法的超长距离跨海高程传递方法,设计了具体的测量方案,包括跨海场地选定与布设,观测标灯设计与制作,跨海观测时段数、测回数及组数设计,观测程序与观测方法、观测成果的限差验算与成果取舍等,并提出了跨海高程传递精度评定的两种方法。在平潭海峡公铁两用大桥工程现场选定两条跨海线进行了实验研究,实验结果表明,13.9km和18.0km跨距的跨海高差平差值与已知高差的较差均小于二等水准测量限差,每千米跨海高程测量中数的中误差分别为±0.68mm和±0.63mm。 相似文献

J. C. Boardman 《The Photogrammetric Record》1994,14(84):925-942
Photogrammetrists are acutely aware that remote methods of survey are commonplace. However, it is only relatively recently that high precision levelling of the national motorway network has been conducted in this manner. There are now several competing methods available, all of which have gained some acceptance. This paper describes a low level aerial photographic method employing a helicopter as the platform. It begins with the reasons for the development, describes the system and methods involved, addresses the safety aspects, attempts to outline the necessity for the largest scale possible to maintain precision, analyses the potential developments and discusses the advantages and disadvantages compared with ground based systems. 相似文献

AbstractThe object of the instrument and special staves is to enable levelling observations to be carried on in conditions of heat-shimmer which would hinder or prevent work by the ordinary methods. The instrument can, however, be used as an ordinary level in normal conditions. The staves for use with the instrument are marked with main bull's-eyes at intervals of 10 cm. and smaller intermediate bull's-eyes at the half-intervals (5cm. from each main bull's-eye). These intervals can be replaced by English units, if desired, and the reverse faces can also be marked with ordinary graduations for use in clear and steady conditions. 相似文献

The use of GPS for establishing height control in an area where levelling data are available can involve the so-called GPS/levelling technique. Modelling of the GPS/levelling geoid undulations has usually been carried out using polynomial surface fitting, least-squares collocation (LSC) and finite-element methods. Artificial neural networks (ANNs) have recently been used for many investigations, and proven to be effective in solving complex problems represented by noisy and missing data. In this study, a feed-forward ANN structure, learning the characteristics of the training data through the back-propagation algorithm, is employed to model the local GPS/levelling geoid surface. The GPS/levelling geoid undulations for Istanbul, Turkey, were estimated from GPS and precise levelling measurements obtained during a field study in the period 1998–99. The results are compared to those produced by two well-known conventional methods, namely polynomial fitting and LSC, in terms of root mean square error (RMSE) that ranged from 3.97 to 5.73 cm. The results show that ANNs can produce results that are comparable to polynomial fitting and LSC. The main advantage of the ANN-based surfaces seems to be the low deviations from the GPS/levelling data surface, which is particularly important for distorted levelling networks. 相似文献

如何更合理完善地制定一种判别测量成果质量的标准,是一个很有研究价值的课题。本文对在水准测量中用控制图表充实现行的固定限差法判别测量成果质量作了初步尝试,在统计检验原理的基础上,提出了判别限差内水准测量成果的三条准则。用极其简单、直观的控制图表,能对限差内的成果可能出现的异常及时作出判断。若以此监控水准测量生产,不仅方便可行,且能收到较好的经济效益,更重要的是对提高成果质量也大有裨益。 相似文献
