“天地图·上海”与主节点数据融合方案研究

Research on Data Fusion Solution between “Map World Shanghai ”and “Map World”

围绕"天地图·上海"与主节点数据融合方案的制订,分别对双方的数据内容、融合的技术流程、实现融合的关键技术等进行了研究。主要的研究内容包括:分析对比数据找出差异,确立融合原则和内容,制定技术流程,在对双方资料做详细分析的基础上,解决海量数据存储、处理和管理技术、专题数据变化检测和提取技术、数据自动检查和处理技术等关键技术问题。经过35 km^2数据试点,融合方案达到了预期目标,试点成果满足了主节点的要求,证明了本方案设计路线可行。

The article discusses the key technology of data fusion between Map World Shanghai and the main node. The main research contents include finding out the differences by sample data analysis, establishing the fusion principle, content, technical process and key technical problems involved. The key technical problems are the storage, processing and management of massive data, thematic data change detection and extraction, automatic data checking and processing etc. Tested by the sample data of 35 km^2, the fusion results meet the requirements of the main node, the fusion solution has achieved the anticipative target and the technology design is feasible.
