摘要
针对当前多源基础地理信息数据一致性不好、质量参差不齐、定制衍生能力弱等现实问题,本文在分析地理信息相关“一张图”现状基础上,提出了基础地理实体底座“一张图”数据模型概念,并给出了模型的数学定义和以地理实体为核心的数据结构,设计了涵盖资料分析整理、数据择优融合和产品灵活定制等关键环节的模型应用体系架构。通过试验验证,该模型具有可行性和有效性。模型研究成果能够实现多源地理信息数据高效融合利用,同时为新型基础测绘建设提供一条高效集约化技术路径,以期推动地理信息数据生产、更新、管理、应用模式的创新,为国民经济和国防建设发展提供精准、可靠、统一、高效的地理信息服务。
In view of the current practical problems such as poor consistency,uneven quality,and weak customization and derivation ability of multi-source fundamental geographic information data,on the basis of analyzing the current situation of“one map”related to geographic information,the concept of“one map”data model of fundamental geographic entity base is proposed,and the mathematical definition of the model and the data structure with geographic entities as the core are given,and the model application architecture covering key links such as analysis and collation of data,merit-based fusion of data and flexible customization of products is designed.The experimental verification shows that the model is feasible and effective.The research results of the model can realize the efficient integration and utilization of multi-source geographic information data,and at the same time provide an efficient and intensive technical path for the construction of new fundamental surveying and mapping,which is expected to promote the innovation of geographic information data production,updating,management and application mode,and provide accurate,reliable,unified and efficient geographic information services for the development of national economy and national defense construction.
