| Abstract: | 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. |
