摘要
针对数量日益增长的多源、异构遥感影像组织与管理问题,在分析遥感影像特点的基础上,设计并实现了海量遥感影像高效可视化管理系统。研究了系统的组织架构,借助三维地球技术,提升系统的可操作性与视觉体验;采用元数据库技术,实现海量、多分辨率遥感影像的统一、快速查询、检索与定位;通过遥感影像缩略图、金字塔模型和线程池机制,提高遥感影像读取及可视化显示的效率。最后,完成了基于三维地球的遥感影像可视化管理系统的功能集成,实现遥感影像的多种管理模式和多层次需求。在此基础上,在实际工程应用中为海量遥感影像的分发服务提供有力的技术保障。
Remote sensing images play a more and more important role in the present social life and economic construction. For the organization and management issues of massive multi-source and heterogeneous remote sensing images, this paper designs and implements an efficient visualization management system for massive remote sensing images based on the characteristics of remote sensing images. This study included the organizational structure of the system and enhanced the operability of the system and the visual experience by the technology of three-dimensional globe. Combining xml file with database,we designed an effi cient and unified metabase, which achieved an efficient query, retrieval and positioning function for massive, multi-resolution remote sensing images. Through low-resolution thumbnails, multi-resolution pyramid model and high concurrent thread pool, the efficiency of loading and visual display was significantly improved. Finally, using the above techniques, we completed a three-dimensional globe-based efficient visualization management system,which achieved a variety of management modes and multi-level needs. On this base,this system provides strong technical support for the distribution of massive remote sensing images.
