城市大比例尺地形图数据更新方法及其应用
发布时间:2019-05-13 17:33
【摘要】:以笔者所在单位近几年研制采用的城市大比例尺地形图数据更新方法为例,分析讨论了分别采用机载Li DAR技术、地面Li DAR技术、地图综合缩编软件、建设工程竣工测量成果、传统地形图更新修补测方法进行城市大比例尺地形图数据更新的工作流程、技术方法,对各自优缺点进行了比较,建议5种地形图更新方法相互借鉴补充配合使用。
[Abstract]:Taking the data updating method of urban large scale topographic map developed and adopted by the author's unit in recent years as an example, this paper analyzes and discusses the survey results of construction project completed by using airborne Li DAR technology, ground Li DAR technology, map comprehensive reduction software, respectively. The work flow and technical method of urban large scale topographic map data updating are carried out by traditional topographic map updating and mending methods, and their advantages and disadvantages are compared. It is suggested that five topographic map updating methods should be used for reference and supplement each other.
