在测量和计算数据时，必须要有肯定的技术依据，必须要满意肯定的规范在限制测量中网形的选择尤为重要，我选择了两种网型设计从各方面进行比较，选出最优的网形设计方案确定限制网网形后，起先选点埋石作业，作业时需满意一点的规范并上交规定的资料下面就是依据限制网进行测量，并对数据进行平差处理，对数据精度进行估算，其中的图根限制测量对我来说是比较重要也是比较困难的一个环节，在获得最终的数据结果后，还须要自检，互检登的检查，以确保精度最终依据地形图基础要求来绘制地形图，上交整个测量过程中须要上交的资料关键词：限制网；限制测量；数据处理；平差；布网原则毕业设计（论文）外文摘要The 1: 500 Digital Topographic Map TechnicalDesign of Punan Industrial ZoneObstract：The core of design is to produce topographic maps, the purpose of topographic map production is to provide services for the planning of Lianyungang, Lianyungang extension of land information database. Our main task is to control the plane measurements, vertical control survey, topographic survey.Plane Control Survey is based on specifications laid E-class GPS control network, based on a planar control measurements, height measurement is mainly carried out using a spirit level, topographic survey is mainly topographic map use of existing data and measurements needed to draw.In the measurement and calculation data, there must be some technical basis, must meet certain specifications. Control Survey Network in shape choice is particularly important, I selected two network design aspects to compare, select the best net-shaped design. After determining the control mesh net-shaped stone buried start site selection work, the job must meet that specification and submitted information specified.Here is measured according to the control network, and data adjustment processing, data accuracy estimate, which mapping control surveying for me is more important and difficult aspect in obtaining the final data results, also need self-inspection, mutual inspection board checked to ensure accuracy. Finally, in accordance with the requirements of basic topographic map topographic map, is turned over to the entire measurement process needs to hand over information.Keyword：Control Network；Control Survey；data processing；Adjustment；principle of net 目 录1.绪论--------------------------------------------------------------12.测区自然地理概况--------------------------------------------------13.主要工作程序及任务------------------------------------------------2 3.1测量的主要工作程序---------------------------------------------2 3.2主要任务-------------------------------------------------------24. 已有资料及此次测量的技术依据--------------------------------------2 4.1已有资料-------------------------------------------------------2 4.2测量的技术依据------------------------------------------------3 5.基础限制测量------------------------------------------------------3 5.1平面坐标系统的选择及其论证-------------------------------------3 5.2平面限制测量---------------------------------------------------4 5.3E级GPS限制网布网方案------------------------------------------5 5.4选点埋石------------------------------------------------------11 5.5观测要求及记录------------------------------------------------14 5.6E级GPS网数据处理---------------------------------------------16 5.7一，二GPS限制测量--------------------------------------------186.高程限制测量-----------------------------------------------------20 6.1高程基准和水准等级的选择--------------------------------------20 6.2网形设计------------------------------------------------------21 6.3选点，埋石，及应交资料----------------------------------------22 6.4施测方法------------------------------------------------------24 6.5验算与平差计算------------------------------------------------257.图根限制测量-----------------------------------------------------26 7.1基本要求------------------------------------------------------26 7.2图根导线测量--------------------------------------------------27 7.3图根点高程测量------------------------------------------------28 7.4图根导线平差计算----------------------------------------------28 7.5采纳GPS RTK 方法测定图根点-----------------------------------288.地形图测绘-------------------------------------------------------29 8.1基本要求-----------------------------------------------------29 8.2地貌测绘的要求------------------------------------------------31 8.3地形图编辑----------------------------------------------------319.地形测量成果的质量限制与资料提交---------------------------------31 9.1质量限制流程--------------------------------------------------32 9.2检查方式------------------------------------------------------32 9.3质量监理------------------------------------------------------33 9.4资料提交------------------------------------------------------3310.结论-----------------------------------。
