1：500地形图测绘设计技术测量毕业论文.doc

毕 业 论 文 题 目：1:500地形图测绘设计技术 英文题目：1:500topographic map surveying design technology 摘要：本设计主题为：1:500地形图测绘技术设计，是实施、结合实际主要从图根控制网的设计布设、实测和利用全站仪对碎步点进行的采集方法以及碎步点数据的处理三方面做了探讨；也非常详细的阐述了全站仪在数字测图中运用，以及大比例尺测图的方案；最终使用全站仪或RTK测出符合要求的大比例尺数字地形图，1:500数字化测图以其成图精度高，成图周期短，即用即测，快速建立城市大比例尺基础地理信息数据库定特点，已被一些城市建设规划管理的领导所青睐和引用。随着测绘科学技术的反战，全数字地形测图在现代制图技术下已经发展成为了高新的制图技术 数字测图的基本思想是将地面上的地形和地理要素（或称模拟量）转换为数字量，热爱后有计算机对其进行处理，得到内容丰富的电子地图，需要时有图形输出设备（如显示器、绘图仪）输出地形图或各种专题图图形。将模拟量转换为数字这一过程通常称为数据采集。目前数据采集方法书要有野外地面数据采集法、航片数据采集法、原图数字化法等。数字测图就是通过采集有关的绘图信息并及时记录在数据终端，然后再室内通过数据接口将采集到的数据传输给计算机，并由计算机对数据进行处理，再经过人机交互的屏幕编辑形成绘图数据文件，最后由计算机控制绘图仪自动绘制所需的地形图，最后又磁盘、光盘和硬盘等储存介质保存电子地图。数字测图生产成品虽然仍然提供图解地形图为主，但是它以数字形势保存着地形模型及地理信息。 关键词：1:500地形图 数字测图 要素 采集 设计 碎部点 Abstract：The design theme is: 1: 500 topographic map surveying and mapping technology and design, combined with the actual implementation, is mainly from the mapping control network design layout, survey and the use of total station in scattered points for collecting method and data processing for scattered points in three aspects were discussed; also very detailed description of the total station in digital mapping map use, as well as large scale mapping of the scheme; finally using total station or RTK measure to meet the requirements of large scale digital topographic map,1:500 Digital Mapping of the mapping precision, a short cycle, use namely, rapid establishment of city large scale basic geographic information database set features, has been some city construction planning management leadership favored and references. Along with the science and technology of surveying anti-war, digital topographic mapping in modern cartography technology has developed into a new mapping technology Digital mapping is the basic idea of the ground topography and geographic elements ( or analog ) is converted to a digital quantity, love after the computer carries on the processing, has the rich content of the electronic map, need to have the graphical output device ( such as a di
