摘要
高光谱遥感数据具有海量、高维、图谱合一等技术特点,随着数据量的增加,传统的文件管理方式越来越无法满足实际的需要。本文提出了将高光谱遥感数据按像元顺序或者波段顺序分割,按大型对象存储的技术思路,设计了高光谱遥感数据的存储结构,并开发了相应的数据管理平台。实际应用表明,该平台能够较好地完成高光谱数据的存储、管理与查询,取得了理想的应用效果。
Hyperspectral remote sensing data are characterized with massive data, high dimension and image-spectrum incorporation. With the increasing of data volume, the typical file management system can not satisfy the practical needs. This paper puts forward a method which divides the hyperspectral remote sensing data into large objects by pixel sequence or band sequence, and stores the large object in the database management system, and has designed a management platform with general structure to store and manage hyperspectral remote sensing data. The application shows that this platform is fairly efficient in data store, management and query.
