【摘要】 研究了遥感专题信息数据、常规观测信息数据以及地理信息数据。三类数据其来源不同,组织方式不同,存储格式也不同,如何在遥感信息提取平台上综合运用它们进行多维、动态显示与处理,是系统研发的一个瓶颈问题。根据海洋数据特征,建立能够对矢量、栅格以及时间数据综合处理的一体化时空模型,实现其数据结构,并使用“海洋一号”卫星数据进行模型验证。实验结果表明,该数据结构可以满足多源遥感数据的多维动态显示与处理的要求。更多还原

【Abstract】 In this paper, the main marine data, including remote sensing thematic information data, conventrional observed information data and geographic information data are studied. The origins, organization forms and storage formats of three types of data are different from each other, so how to integratedly use these data to realize the multi dimensional and dynamic data visualization and processing on a remote sensing information retrieval platform has become a bottle neck in the system development. In this paper, based on the marine data characteristics, a united spatio temporal model to integratedly deal with the vector, grid and time data is established to set up their data structures, and the HY 1 satellite data are used to validate the model. It is shown from the validation results that the data structure can meet the requirements for multi dimensional and dynamic visualization and processing of multiorigin remote sensing data.更多还原
