海洋GIS时空数据组织框架模型研究

Study of Marine GIS Spatiotemporal Data Organizing Frame Model

通过对现有海洋GIS时空数据组织模型的评述,从海洋基础数据出发,以实用、高效的海洋时空数据的组织管理和应用为目标,提出了海洋GIS时空数据组织框架模型,该框架从原始海洋数据集的定义、海洋GIS时空数据仓库的内涵、时空数据的组织层次、算法的应用层次等多个方面进行了全新的描述和设计,使海洋时空数据的组织过程更加详尽、清晰。

Through commenting the present marine GIS spatialtemporal data organizing model, beginning from the basic marine data, aiming at the organizing management and application of the practicable and high-performance spatialtemporal data, this paper brings forward a new marine GIS spatialtemporal data organizing frame model. The frame gives a new description and design for the definition of marine basic data set, the connotation of marine GIS spatialtemporal data warehouse, the data organizing hierarchies, the algorithmic applying hierarchies, and so on. It makes the marine spatialtemporal data organizing procedure more thorough and clear.
