遥感影像数据模型及影像数据库的建立

The Data Model of Remote Sensing Image and Its Implementation in RDBMS

在总结图像数据模型研究的基础上 ,分析了遥感影像的种类、一般存储方式、影像与具体应用的关系 ,指出了遥感图像管理的特殊性 ,提出了遥感影像在关系数据库中的逻辑表达模型 ,讨论了该模型支持下的基于图像内容的查询问题 ,最后介绍一个遥感影像数据库的设计原型。

A detailed analysis was carried on the classification, physical storage and relation with application of remote sensed image. A logical model of remote sensing imagery presentation in relation database was provided and the content based image retrieving problem was discussed too. Finally, an image database prototype based on the suggested model and its implementation was introduced.
