基于多源空间数据集成研究现状分析,提出了利用SuperMapSDX+空间数据引擎的数据直接访问模式来实现多源图像情报空间数据集成的构想;设计了空间数据库的多源图像情报内容体系结构,构建了多源图像情报空间数据的存储模式和集成管理模型;研究了组件式GIS的技术特点和应用优势,分析了多源空间数据无缝集成技术的体系结构。在此基础上,设计了多源图像情报空间数据集成应用技术方案框架结构,最后开发了原型系统,验证了本文理论的合理性。研究成果较好地实现了多来源多影像格式和多情报样式的空间数据集成,并基于数据集成进行了目标图像情报查询、对比辅助判读和目标专题制图应用。
Based on an analysis of the research progress of multisource spatial - data integrating, this paper puts forward an idea to integrate muhisource image intelligence spatial - data just in the pattern form which accesses spatial data directly by using SuperMap SDX + spatial - data engine. The contents system structure of the spatial database was designed and the accessing pattern and the integrating model were analyzed. Then the integrating technological frame structure was designed based on the study of GIS with its application superiority and the technological system structure of Seamless Integration of Multisource Spatial Data. Its Database Prototype was actualized so as to prove the rationality of the proposed theory. The research achievement has resolved preferably image intelligence spatial data integration characterized by multi -source, multi -format and multi -modality. On the basis of data integration, the application of target intelligence inquiry and assistant image interpretation by contrast and target theme -mapping was actualized.
