摘要:

波谱模拟模型在遥感应用中至关重要,但是传统的波谱模拟模型应用主要是基于单机版的应 用,模型模拟的结果不能广泛共享,并且利用波谱数据库的支持也十分有限。试图突破这种局限,以波 谱模拟模型在遥感中的应用为主线,参照知识库系统建设的理论,采取B/S的网络结构,充分利用波谱 数据库和先验知识库的强大支持,建立分布式波谱模拟模型的应用系统,通过一定的规则和算法自动从 波谱数据库和先验知识库中调用数据和知识作为模型的输入参数;对于模拟的结果,可以根据用户意愿 决定是否录入波谱数据库,作为知识库系统的知识获取机制,为用户进行遥感应用提供了一个有力的支 持平台。

Abstract:

The application of spectrum simulation model in remote sensing is extremely important, whereas in the traditional way, this model was used normally in a single computer. Its simulated results can hardly be shared with others, and it can be limited to be supported using spectrum database techniques as well. As a clue of the application of the model in remote sensing, the paper tries to break through this limitation, and constructs the distribution application system based on the spectrum simulation model, referenced to the theory of constructing knowledge database system, which is adopted Browser/ Client network structure. The built distribution application system is enough supported by the spectrum database and prior- knowledge library. It can extract and transfer the data and knowledge from these two databases as an input parameter for the model automatically with some regulations and algorithms. For the results of simulation, user can decide whether or not to use the spectrum database as a knowledge capture mechanism of knowledge library system. This system provides a strong software platform in remote sensing application for the users.
