基于工作流的基础地形数据建库及动态更新关键技术研究与实现

Research and Realization of the Key Technologies of Basic Terrain Database and Dynamic Updating Based on Workfl ow

基于南京市国土资源"一张图"总体架构,提出了Oralce Spatial 11g+FME Server的一体化地形数据库建库策略,实现了B/S模式下基于工作流的对任意范围地形的快速更新与智能检查,形成了要素级元数据的管理模式,并在生产中得到实际应用。

Based on overall architecture of ＂One Map of land resources of Nanjing city, this paper proposed same strategies of building the terrain database of Oralce Spatial 11 g ＋ FME Server, and realized the rapid updating for any range of terrain and intelligent inspection under the B/S mode, based on workflow; it formed the management approach of elements metadata and used it in the actual production.
