【摘要】：在一些對實時性要求很高的應用中，例如洪水災害預警系統(tǒng)，水文數(shù)據(jù)每時每刻都會有變化，而這些實時數(shù)據(jù)對于決策中心的決策者而言是至關重要的，因此本文重點研究水文數(shù)據(jù)的存儲、組織和發(fā)布及集成應用。 地理信息系統(tǒng)(GIS)是一種可融合進不同系統(tǒng)框架的技術，能采集、存儲、分析和顯示地理參考信息，它允許我們以一種快速理解和方便共享的方式瀏覽、理解、查詢、解譯和可視化數(shù)據(jù)；另一方面，Web服務是建立于XML、SOAP、WSDL、UDDI等開放標準之上，實現(xiàn)兩個應用系統(tǒng)之間的互操作性的體系結構�，F(xiàn)在我們擁有了兩個獨立的技術：GIS和Web服務，他們的結合點是集成一個滿足下面要求的水文時空數(shù)據(jù)集成系統(tǒng)，即GIS提供地圖和空間對象，而Web服務提供接入水文時間序列數(shù)據(jù)的接口。 在水文時空數(shù)據(jù)集成系統(tǒng)的設計及實現(xiàn)過程中，為了更好地體現(xiàn)水文時空數(shù)據(jù)的特點，本文詳細分析了ODM觀測數(shù)據(jù)存儲模型和WaterML語義模型：ODM數(shù)據(jù)模型建立于關系數(shù)據(jù)模型上，包含觀測數(shù)據(jù)、觀測站、數(shù)據(jù)源、觀測變量、觀測時間、數(shù)據(jù)采集方法、數(shù)據(jù)質量等信息，該模型主要研究這些數(shù)據(jù)之間的聯(lián)系及組織結構，該模型可以彌補現(xiàn)有時空數(shù)據(jù)模型不能存儲水文時間序列數(shù)據(jù)的問題；而WaterML作為一種XML結構的語言，定義了Web服務方法中的所有元素的結構,一方面作為Web服務實現(xiàn)時設計Web服務方法中水文數(shù)據(jù)類結構的依據(jù)，，另一方面Web服務調用者也可以此規(guī)范來調用Web服務，易于開發(fā)和維護不斷變化的客戶應用程序。 本論文使用GIS技術，以.NET與ArcGIS Engine為開發(fā)平臺,以Web服務技術框架為基礎，構建了一個水文時空數(shù)據(jù)集成系統(tǒng)，該系統(tǒng)集成了水文觀測時間序列數(shù)據(jù)及空間數(shù)據(jù)，并實現(xiàn)了數(shù)字地圖顯示、水文數(shù)據(jù)查詢、水位監(jiān)測及預警等功能。
[Abstract]:In some applications that require high real-time performance, such as flood warning systems, hydrological data vary from time to time, and these real-time data are critical for decision makers in decision-making centers. Therefore, this paper focuses on the storage, organization, distribution and integration of hydrological data. Geographic Information system (GIS) is a technology that can be integrated into different system frameworks. It can collect, store, analyze and display geographic reference information. It allows us to browse, understand and query in a way that can be quickly understood and easily shared. On the other hand, web services are based on open standards such as XML,SOAP,WSDL,UDDI to achieve interoperability between two application systems. Now we have two separate technologies called: GIs and Web Services, which combine to integrate a hydrological space-time data integration system that meets the following requirements: GIS provides maps and spatial objects. The Web service provides access to hydrological time series data. In the course of the design and implementation of hydrological space-time data integration system, in order to better reflect the characteristics of hydrological space-time data, this paper analyzes in detail the ODM observation data storage model and the WaterML semantic model: ODM data model established on the relational data model. It contains information such as observation data, observation station, data source, observation variable, observation time, data acquisition method, data quality and so on. This model can make up for the problem that the existing spatio-temporal data model can not store hydrological time series data, and WaterML, as a language of XML structure, defines the structure of all the elements in the Web service method. On the one hand, it is the basis of designing the hydrological data class structure in the Web service method when Web service is implemented; on the other hand, the Web service caller can call the Web service with this specification, which is easy to develop and maintain the changing customer application program. In this paper, a hydrological space-time data integration system is constructed on the basis of GIS technology,. Net and ArcGIS Engine, based on the framework of Web service technology. The system integrates hydrological observation time series data and spatial data. The functions of digital map display, hydrological data query, water level monitoring and warning are realized.
