[Abstract]:Coastal zone plays a more and more important role in human production and life and scientific research, and China's coastal zone is facing more and more severe challenges of resources and ecology. In the face of the massive increase of coastal zone data resources, it is urgent to strengthen the management of coastal zone related data. Based on the analysis of the present situation of integrated coastal zone management at home and abroad, this paper mainly studies the organization and management of coastal space-time data and the construction of information platform. In the process of studying the technology of coastal space-time information platform, the following aspects are studied in this paper: (1) the conceptual model and logical model of object-oriented coastal space-time object are studied and constructed. By analyzing the characteristics of coastal zone data, summing up the advantages and disadvantages of the existing space-time element model and space-time field model, the conceptual model and logical expression model of space-time object are constructed. The space-time field data and dynamic element data are expressed uniformly. (2) the organization structure of coastal space-time data is studied and designed. In order to solve the problems of redundancy and complexity in the data transmission and analysis of the traditional data structure in the network client, according to the object-oriented design idea, this paper designs the spatial and temporal data organization structure (TGeoJSON). TGeoJSON not only adapts to the expression of the characteristic information of the spatial and temporal data. Network transmission, data visualization and other requirements, but also conducive to the management and maintenance of data, conducive to the storage and expansion of object-oriented data, At the same time, it is beneficial to the index construction based on location elements. (3) the visual representation method of coastal space-time data is studied and designed. On the basis of analyzing the general data visualization method, the visualization method of space-time process data is discussed, and a new visualization design concept and scheme are put forward. Through the design and construction of space-time oriented dynamic visual representation method of coastal zone, the need of temporal change expression caused by the spatial and temporal data structure of coastal zone or the time, space and attribute of temporal and spatial objects is solved. On the basis of conquering the key technologies, the space-time information platform of coastal zone is studied and constructed. In this paper, the acquisition and processing of temporal and spatial data, the organization and scheduling of spatial and temporal data, the visualization and analysis of spatial and temporal data information are analyzed. The design scheme of five-tier architecture of coastal space-time information platform is put forward, including data resource layer, data management layer, service logic layer, functional module layer, user management and security service system. According to the data source, characteristics and types of coastal zone, the spatial and temporal database of coastal zone is designed. On this basis, the technical analysis of the platform function module is carried out, and the prototype system is developed to verify the system, which includes the space-time data organization and storage module, the space-time data management and scheduling module, and the local detail level space-time data module. Space-time data information visualization module, space-time data analysis application module five functional modules.
