多任务地理实体网格化数据联动更新工作机制研究

Research on Working Mechanism of Multi-task Geographic Entity Grid Data Joint Update

在新的自然资源管理体制下,测绘地理信息工作逐步融入自然资源管理与生态文明建设的大格局中,测绘任务日益繁重,如何快速及时更新众多测绘任务的时空数据库,并建立新的更新模式是亟待解决的问题。本文引入了网格化管理的概念,提出了基于地理实体的联动更新工作机制,有效提高了多任务地理信息数据库的更新效率。

Under the new system of natural resource management, surveying and mapping geographic information work is gradually integrated into the natural resource management and ecological civilization construction, and the surveying and mapping task is increasingly heavy. How to quickly and timely update the spatio-temporal database of many surveying and mapping tasks, and establish a new update mode is an urgent problem to be solved. In this paper, the concept of grid management is introduced, and a joint update mechanism based on geographic entities is proposed, which effectively improves the update efficiency of multi-task geographic information database.
