| 摘 要： | 基于来自空间和常规的海岸带及近海多源信息,旨在满足国家空间数据基础建设和应用的迫切需求,在对诸多信息特征进行分析的基础上,建立了中国海岸带科学数据平台概念模型,并在此概念模型的基础上进行了具体的逻辑结构、遥感影像数据的ARCSDE存储、遥感数据的元数据存储等模型设计.同时阐述了多源数据空间组合的复杂技术及其关键意义,一俟由此实现海岸带及近海数据库建立和系统业务化运行,便可更加有效地为海岸带及近海调查、研究、开发应用和管理提供智能化信息分析的平台和技术服务.

| Abstract: | To meet the increasing demand of national spatial database infrastructure construction and application,a concept model of China's coastal zone science data platform is established based on the information feature analysis of a compound dataset consisted of remote sensing data and conventional data of coast zone and offshore.Based on this concept model,the detailed logical database structure and the storage strategy of remote sensing data and its metadata using ARCSDEare desig ned.The complicated technology of multi-sources data combination in this research is crucial to the future coastal zone and offshore database construction and practical running,which will provide intelligent information analysis and technological service for coastal zone and offshore investigation,research,development and management. |
