摘要
随着社会经济建设的不断发展,城市测量任务日益繁重,如何将获取的地理信息数据及时更新到城市空间数据库中,并建立快捷、经济的动态入库更新模式是亟待解决的问题。本文在常规实时动态更新基础上,引入了网格单元的概念,提出城市空间数据库网格化动态更新机制,并通过广州全市范围网格化动态更新和南沙区精细网格化动态更新的实践应用,验证了机制的可行性和可推广性。
With the continuous development ot economic construction, urban measurement task is being increased, therfore how to establish a last and economic mode to dynamic update about urban spatial database becomes a serious problem. Based on the conventional real-time update, this paper introduced the concept ot grid cells, proposed grid dy- namic update mechanism, and took Guangzhou and Nansha as an example to verify the feasibility and replieability of the grid dynamic update mechanism.
