摘要
在数字城市基础地理空间框架建设中,影像数据是其中核心数据之一,是重要的建设内容。这些数据具有多源、多分辨率、多时相的特点,为方便这些数据的管理和利用,需对它们进行高效地组织管理。在分析现有的影像数据管理技术的基础上,采用文件数据库混合存储,基于ArcEngine的组件开发影像管理系统,实现影像入库、查询展示、分析决策、数据分发服务等功能,满足影像管理的需求。
In the construction of digital urban infrastructure geospatial framework, the image data is regarded as one of the core data which has become an important building task. These data has characteristics of muhi-source, multi-resolution, and multi-temporal phase. In order to facilitate the management and use of these data, the efficient management is needed. On the basis of the analysis of existing image data management technology, the mixed file database storage and video management system based on ArcEngine components are used to achieve the image storage, query and display, decision-making analysis, data distribution services in order to meet the image management needs.
