摘要
基础地理信息数据为自然资源调查监测提供了有效的地理数据框架和本底数据,为自然资源管理"两统一"职责提供了基础保障。为了解决因地理信息数据的多样性差异而导致的融合效率低下问题,提出了一种一体化动态更新方法。采用统一的数据库模板、提取规格、提取流程和融合入库标准,利用一体化的生产平台对地理信息数据的动态更新进行了研究,极大地提高了数据融合效率,进而充分发挥了地理信息数据的应用价值。
Basic geographical information data can provide an effective geographical data framework and background data for natural resource survey and monitoring,and provide a basic guarantee for the "Two Unification" of natural resource management.In this paper,in order to solve the problem of low integration efficiency caused by diversity difference of geographical information data,we proposed an integrated dynamic update method,which using the unified database template,extraction specification,extraction process,integration warehousing standards,and the integrated production platform to dynamic update geographical information data.This method can greatly improve the efficiency of data integration,in order to give full play to the application value of geographical information data.
