基于GIS的多源遥感影像管理显示系统的设计与实现

影像数据具有多时相、数据量大的特点,这给影像数据的集中统一管理提出了更高的要求。如何结合GIS空间数据管理优势管理影像数据,实现矿区影像的快速入库与高效查询,是本文所要探讨的主要内容。本文在分析不同影像类型在磁盘上的存档特点,以及头文件内容的基础上,确定了影像元数据库结构并设计了头文件自动解析模块,实现了影像的数据文件及其相关元数据的快速入库,开发了基于Arc GIS Engine的影像管理查询检索系统,实现了基于空间和属性的快速查询检索,并且在元数据的支持下实现了影像和元数据的双向查询。

Design and Implementation of the System of Multi-Source Remote Sensing Image Management GIS Display

Mineral resources are abundant, but widely distributed, which put a higher demand for centralized management of remote sensing image data in mining area.How to manage remote sensing images relatively concentrated and separated mining areas, com-bined with powerful GIS spatial data management advantages, which is the main research and explore directions.On the basis of anal-ysis characteristics of different type of images and contents of header files, this paper confirmed contents of metadata base and designed automatically parsing module to header files, implemented quickly storage of image data files and metadata, designed and developed image query and retrieval system based on ArcGIS Engine,This system implemented quickly query based on spatial and attribute, and implemented two-way query between image data and metadata.
