【摘要】：中国各遥感应用需求部门对于需求的描述存在很大差别,而且需求之间有一定相关性,给后续遥感传感器的设计带来很大不便.针对这个问题,以多光谱应用需求为例,提出一种需求综合方法.首先将相关部门的原始需求以基于领域本体建模的方法进行结构化表达,建立相应的需求数据库以保证数据共享性,然后构建多光谱应用需求空间分辨率 时间分辨率的需求分类决策树.与中国空间基础设施规划的对地观测多光谱应用需求进行比较,并对分类方法进行评估.结果表明,该方法能获取良好的综合后需求,可直接用于后续遥感传感器的设计与评估.
[Abstract]:The requirement description of remote sensing application departments in China is very different, and the demand is related to each other, which brings great inconvenience to the design of remote sensing sensor.In order to solve this problem, a method of requirement synthesis is proposed, taking the requirement of multispectral application as an example.Firstly, the original requirements of relevant departments are expressed structurally by the method of domain ontology modeling, and the corresponding requirements database is established to ensure the data sharing.Then, the decision tree of multi-spectral application needs spatial resolution and temporal resolution is constructed.Compared with the requirements of Earth observation multispectral applications in space infrastructure planning in China, the classification method is evaluated.The results show that this method can obtain good post-synthetic requirements and can be directly used in the design and evaluation of remote sensing sensors.
