摘要
随着全国实景三维建设脚步的不断加快,实景三维基础地理实体数据的生产迫在眉睫,城镇开发边界内的大比例尺地形图数据作为实体数据重要的转换源之一,如何对其进行快速更新就显得尤为重要。本文以数字醴陵地理信息基础工程建设生产为例,介绍了利用苏州真鉴信息科技有限公司研发的Pips测图云软件,探讨利用无人机单镜头正射航飞技术进行空三机密过程中遇到的问题及解决办法,并将其应用于大比例尺地形图数据更新时的精度分析。
With the acceleration of the pace of national 3D construction, the production of 3D basic geographic physical data is imminent. As one of the important conversion sources of physical data, how to up-date the large scale topographic map data within the urban development boundary is particularly important. Taking the construction and production of digital Liling geographic information infra-structure project as an example, this paper introduced the Pips mapping cloud software developed by Suzhou Zhenjian Information Technology, and discussed the problems and solutions encoun-tered in the process of using UAV single-lens direct flight technology for air and air classification, and applies it to the accuracy analysis of large scale topographic map data updating.
