摘要
近年来,城市发展日新月异,现存地形图明显滞后于城市发展,因此地形图动态更新很有必要,于是研究城市基础地形图更新方法有很大的现实意义。本文结合2012-2013年杭州市余杭区地形图动态更新的工程案例,主要研究地形图更新的方法,包含更新的要求、过程、原则、内容、目的和意义,并介绍数字地形图更新过程中存在的问题以及一些注意事项。
In recent years, city development change rapidly, the existing topography significantly lagsbehind the city development, therefore the dynamic updating of topographic map is necessary, so the city basic topographic map is of great realistic significance to update method. In this paper, combined with the 2012 --2013 years in Hangzhou city Yuhang District of topographical map updating dynamic engineering case, method to study topographic map update, update Contains requirements, process, principle, content, purpose and meaning, and introduces the digital topographic map update process and some matters needing attention.
