地形图修测与补测.docVIP

摘要 地形图是社会建设必需的基础资料。随着社会的快速发展，对地形图的要求也越来越高，不仅要有较高的精度，而且还要具有极强的现势性。即充分反映地形地貌以及各种设施。为了保持地形图的现势性，满足社会发展建设的要求。必须对地形图进行经常性的补测与修测。因此，研究地形图的补测与修测方法具有重要理论意义和现实意义。 本文总结并介绍了传统的地形图补测修测方法，主要有距离交会法、支距法、设站法和透绘法。但这些方法不仅耗费大量的人力物力，而且成图周期长，难以满足建设规划用图的要求。所以又总结了地形图补测修测的新方法，包括利用实时动态（RTK）定位系统修测地形图、数字摄影测量在地形图补测修测中的应用。它可以及时反映地形地物的变化，保持地形图的现势性。 关键词：地形图、补测、修测、RTK、数字摄影测量 Abstract Topographic map is the necessary basic data of the social construction .With the rapid development of the society，On the map are increasingly high requirements，Not only have high accuracy，has a very strong reality.That fully reflect the topography of the land and facilities.In order to keep the currency of topographic map，To meet the social development demand.Must be supplement measurement and surveying on the map for recurrent.So，Study of topographic map supplement measurement and surveying method has important theory significance and the practical significance. This paper introduces the traditional topographic map supplement measurement surveying method.Mainly with distance intersection method, offset method, station method and through drawing method.But these methods not only spend a lot of manpower and material resources.And the long period of mapping.It is difficult to meet the requirements of construction planning map.It also summarized the topographic map surveying of the supplement measurement method.Including the use of real-time dynamic ( RTK ) GPS Surveying of topographic map，Digital photogrammetry in topographic map surveying supplement measurement application.It can reflect the terrain changes, keep the current topographic map Key words：Topographic map、Supplement measurement、Surveying、Method、 Basic technology、RTK、Digital photogrammetry. 目录 摘要 - 1 - 第一章 绪论 - 4 - 1.1研究背景与目的 - 4 - 1.2地形图补测修测技术研究现状 - 5 - 1.3地形图的补测与修测内容和目的意义 - 5 - 1.4地形图补测修测的要求 - 6 - 第二章 地形图补测修测方法基础技术 - 7 - 2.1地形图的概念、特征、功能与分类 - 7 - 2.1.1定义 - 7 - 2.1.2.基本特征 - 7 - 2.1.3功能 - 8 - 2.1.4地图的类型 - 9 - 2.1.5历史 - 10 - 2.2地形图的补测与修测方法与技术
