【摘要】：海岸带对人类生产生活和科学研究的作用和意义越来越大,我国海岸带正面临资源与生态日趋严峻的挑战。面对海岸带数据资源海量增加,加强海岸带相关数据的管理迫在眉睫。本文在分析国内外海岸带综合管理现状的基础上,主要研究海岸带时空数据的组织管理与信息平台的构建。本文在研究海岸带时空信息平台技术过程中,研究了如下几个方面:(1)研究构建面向对象的海岸带时空对象的概念模型和逻辑模型。通过分析海岸带数据特征,总结现有时空要素模型和时空场模型的优势和缺陷,构建了时空对象概念模型与逻辑表达模型,对时空场数据和动态要素数据进行统一表达。(2)研究设计海岸带时空数据组织结构。针对传统数据结构在网络客户端的数据传输和解析存在冗余、复杂等问题,本文根据面向对象的设计思想,设计时空数据组织结构(TGeoJSON)。TGeoJSON既适应时空数据特征信息的表达、网络传输、数据可视化等需求,而且有利于数据的管理与维护,有利于面向对象数据的存储与扩展,同时有利于基于位置要素的索引构建。(3)研究设计海岸带时空数据可视化表达方法。在分析通用数据可视化方法的基础上,讨论时空过程数据可视化方法,并提出新的可视化设计理念与方案。通过设计构建面向时空的海岸带动态可视化表达方法,解决因海岸带时空数据结构或因时空对象时间、空间、属性而产生的时态变化表达需要。在攻克关键技术基础上,研究构建海岸带时空信息平台。本文分析了时空数据获取与处理、时空数据组织与调度、时空数据信息可视化与分析应用。提出了海岸带时空信息平台五层架构的设计方案,包括数据资源层、数据管理层、服务逻辑层、功能模块层、用户管理及安全服务体系;根据海岸带数据来源、特点和类型等设计了海岸带时空数据库;在此基础上,对平台功能模块进行了技术分析,并研发了原型系统进行验证,实现了包括时空数据组织与存储模块、时空数据管理与调度模块、局部细节等级时空数据模块、时空数据信息可视化模块、时空数据分析应用模块五大功能模块。
[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.
