基于剖分理论的遥感影像模板数据模型

随着数据量的增加和应用需求的扩大，遥感数据的高效组织管理和快捷处理速度已经成为制约遥感技术应用的瓶颈，地球剖分理论和高性能计算为上述问题解决提供了一种可能途径。针对上述问题，结合地球剖分模型，在遥感影像剖分面片的研究基础上，提出了剖分面片模板的概念模型及数据模型，设计了基于剖分面片模板的计算模式，构建了一个小型化剖分遥感影像模板数据库，并通过一个模板化应用的具体实例对上述模型进行了部分验证。实验结果验证了模型的可行性，提高了目标检索的效率。

Research on data model of remote sensing image template based on partition theory

With the increasing amount of data and expanding of application demand, the efficient organizational management and rapid processing speed of remote sensing data have become a bottleneck in the application of remote sensing technology. The earth partition theory and high performance computing provide a possible way to solve the above problem. Combined with global partition model, the conceptual model and data model of partition facet template were proposed based on partition facet of remote sensing image. A computing mode of partition facets based on templates was designed, and a small partition template database was established. A specific example of partition image data template applications was also given for validation. The experimental results demonstrate the feasibility of the data model and improve the efficiency of targets retrieval.
