摘　　要：针对海洋遥感数据多源、异构特点显著、采用传统文件型或关系型数据库难以有效集成管理的问题,该文提出了面向海量多源影像数据集成管理的多传感器影像建模技术。在系统分析各类数据存储、组织结构的基础上,分别构建元数据模型和数据模型;数据模型由惟一标识ID、元数据信息、快视图、空间特征和影像数据实体构成,并由ID进行关联;提出了元数据的自动提取与匹配方法,实现了多源遥感影像数据元数据和快视图的自动提取,以及元数据与数据文件、空间特征和快视图的自动匹配,构成了海量多源遥感影像数据统一入库和集成管理的基础。该文提出的方法在我国海洋部门遥感影像数据管理系统中得到了成功应用,有助于提升现有海洋遥感影像数据集成管理和信息化的服务能力。To address the difficulties of integrating and managing multi-source and multi-structured marine remote sensing imagery through traditional file-based or rational database,this paper proposed a multi-sensor imagery modelling technique targeting at integrated management of multi-source imagery data.Based on a systematic analysis of the infrastructure of data storage and organization,metadata model and data model were contructed for currently documented marine remotely sensed imagery.The multi-source image data model constituted a unique image ID,a metadata table,apreview image,spataial features and image entities,which were connected with each other through the ID.Then an automatic technique of extracting and matching data-model entities was proposed,which extracted metadata information and preview images,and then the data files were matched to spatial features,metadata and preview images.The methods have been successfully applied in our national marine data management system,which significantly promoted the integrated management and information service capabilities of current marine remote sensing images.
