一种大文件多版本遥感影像数据组织管理方法
A Management Method Base on Big File Data Storage Structure and Multi Versions for Remote Sensing Image
【摘要】 近年来,遥感技术的飞速发展使得影像数据的使用也越来越广泛和深入,而影像分辨率的增加,使得数据量急剧增长,对数据的存储和管理提出了很高的要求。针对传统遥感影像数据组织存储的不足,本文提出了一种大文件金字塔数据存储结构,用来高效存储管理影像数据;同时针对多时相遥感影像数据,提出了基于版本机制的影像数据管理模式。实验表明这种方法具有更高的存储检索效率。
【Abstract】 In recent years, the rapid development of remote sensing technology enables the wider and deeper use of image data. The increase of image resolution makes the data quantity increase dramatically, and claims for high demand for the storage and management of the data. Base on this background, the paper proposes the big file data storage structure based on the file system aiming at the deficiencies of the traditional storage structure of image data and the management model of image data based on the version mechanism aiming at the images to be updated. The test has shown its high efficiency.
