【摘要】：水利是國民經(jīng)濟(jì)基礎(chǔ),GIS (Geographic Information System,地理信息系統(tǒng))的應(yīng)用是水利信息化的重要手段及內(nèi)容。GIS在水利行業(yè)的普及應(yīng)用,加速了水利信息化的進(jìn)程,使水利信息數(shù)據(jù)利用、展現(xiàn)更加科學(xué)和直觀,但當(dāng)前多數(shù)水利GIS系統(tǒng)間仍相互封閉,導(dǎo)致水利GIS應(yīng)用系統(tǒng)間存在諸多問題,如數(shù)據(jù)與功能難以共享,造成信息孤島與應(yīng)用孤島。 技術(shù)上,云計算這種面向服務(wù)的新型計算模式及其SaaS (Software as a Service,軟件即服務(wù))的理念為解決當(dāng)前水利GIS存在的問題提供了思路。構(gòu)建水利GIS云服務(wù)平臺,將GIS的處理功能與數(shù)據(jù)包裝成云服務(wù),使用戶通過網(wǎng)絡(luò)便捷地訪問、調(diào)用、獲取自己所需要的服務(wù),從而打破信息孤島與應(yīng)用孤島,實現(xiàn)數(shù)據(jù)與功能的最大化共享、復(fù)用。 基于上述思想,論文對GIS、云計算、云GIS進(jìn)行相關(guān)探討,就水利GIS應(yīng)用現(xiàn)狀進(jìn)行了詳細(xì)分析,認(rèn)為將云計算應(yīng)用于水利GIS是未來的發(fā)展趨勢之 為此,結(jié)合某省水利行業(yè)GIS狀況實例,規(guī)劃設(shè)計了一個私有水利GIS云服務(wù)平臺解決方案,給出了目標(biāo)任務(wù)、總體框架、功能模塊和具體服務(wù)內(nèi)容。在這個方案基礎(chǔ)之上,進(jìn)行了水利GIS云服務(wù)平臺的原型開發(fā),實際搭建了私有云計算環(huán)境,實現(xiàn)了平臺功能,可提供地圖數(shù)據(jù)和功能服務(wù),并采用Java和Flex技術(shù)編程,對平臺原型服務(wù)功能做了測試驗證。 研究和實踐表明,水利GIS云服務(wù)能良好的解決當(dāng)前水利GIS共享存在的問題,水利信息化資源可得到有效的集中調(diào)度和共享復(fù)用。
[Abstract]:Water conservancy is Information System. Application of Geographic Information system (GIS) is an important means and content of water conservancy information. The popularization and application of GIS in water conservancy industry accelerates the process of water conservancy information and makes water conservancy information data be used. The display is more scientific and intuitive, but the majority of water conservancy GIS systems are still closed to each other, resulting in many problems among water conservancy GIS application systems, such as data and functions are difficult to share. Information isolated island and application island. Technically, cloud computing is a new service-oriented computing model and its SaaS / Software as a Service. The idea of software as a service provides a way to solve the problems existing in the current water conservancy GIS. The cloud service platform of water conservancy GIS is constructed, and the processing function and data of GIS are packaged into cloud services. Users can easily access, call and obtain the services they need through the network, thus breaking the island of information and application, and realizing the maximum sharing and reuse of data and functions. Based on the above ideas, this paper discusses the GIS, cloud computing and cloud GIS, and analyzes the application status of water conservancy GIS in detail. It is considered that the application of cloud computing to water conservancy GIS is the trend in the future. For this reason, a solution of private water conservancy GIS cloud service platform is planned and designed, and the target task and overall framework are given in combination with an example of water conservancy industry GIS in a province. Function module and specific service content. On the basis of this scheme, the prototype development of water conservancy GIS cloud service platform is carried out, and the private cloud computing environment is actually built, and the platform function is realized. It can provide map data and function services, and use Java and Flex technology programming, the platform prototype service function has been tested and verified. The research and practice show that the water conservancy GIS cloud service can solve the existing problems of water conservancy GIS sharing, and the water resources can be effectively centralized dispatching and shared reuse.
