【摘要】：雷電是一種常見的天氣現(xiàn)象，是大氣中帶電體的瞬間放電過程，同時伴隨著聲和光的出現(xiàn)。同其它的自然現(xiàn)象相比，雷電具有發(fā)生時間短、影響范圍廣、破壞性強(qiáng)等特點(diǎn)，為此，我們需要加強(qiáng)對雷電的監(jiān)測和管理分析，在分析歷史雷電的基礎(chǔ)上為包括水利工程在內(nèi)的重大工程活動提供有價值的參考數(shù)據(jù)和決策支持。 而傳統(tǒng)的地理信息系統(tǒng)多是使用客戶端/服務(wù)器端模式建立起來的應(yīng)用程序，這種模式的系統(tǒng)專業(yè)性強(qiáng)、功能強(qiáng)大、操作的專業(yè)化程度高、安全性和穩(wěn)定性高，憑借著這些優(yōu)點(diǎn)，在過去的一段時間里，這種地理信息系統(tǒng)取得了廣泛的應(yīng)用，但是隨著互聯(lián)網(wǎng)技術(shù)的發(fā)展和用戶對于分布式操作的需求的增長，如何將互聯(lián)網(wǎng)技術(shù)和地理信息技術(shù)結(jié)合起來，開發(fā)一種既有桌面地理信息系統(tǒng)優(yōu)點(diǎn)又能滿足用戶對分布式操作、降低使用成本的需求的系統(tǒng)就成為一個新的研究方向。 本文將WebGIS系統(tǒng)應(yīng)用在雷電信息的管理上面，既能滿足一般的雷電災(zāi)害預(yù)防網(wǎng)站的功能需求，又能使用戶方便的操作與雷電相關(guān)的空間數(shù)據(jù)。本文首先介紹了雷電相關(guān)的知識和開發(fā)WebGIS（基于ArcGIS Server）系統(tǒng)所需要的技術(shù)，，然后根據(jù)課題的需求分析出了本系統(tǒng)與其它系統(tǒng)的關(guān)系、系統(tǒng)所具備的功能模塊以及各個模塊的設(shè)計開發(fā)方案、根據(jù)系統(tǒng)所用到的雷電數(shù)據(jù)的特點(diǎn)設(shè)計并采用合理的數(shù)據(jù)模型和數(shù)據(jù)結(jié)構(gòu)，確定了系統(tǒng)開發(fā)的方法，最后通過系統(tǒng)在應(yīng)用實(shí)例中的使用驗(yàn)證了系統(tǒng)的穩(wěn)定性、安全性以及在雷電探測數(shù)據(jù)（包括空間數(shù)據(jù)和屬性數(shù)據(jù)）管理方面具有的優(yōu)點(diǎn)，系統(tǒng)能夠很好的把分散在不同地區(qū)和站點(diǎn)的雷電信息組織管理起來，進(jìn)行網(wǎng)絡(luò)的發(fā)布，為廣大用戶提供數(shù)據(jù)支持。
[Abstract]:Lightning is a common weather phenomenon, which is a transient discharge process of charged body in the atmosphere, accompanied by the appearance of sound and light. Compared with other natural phenomena, lightning has the characteristics of short time, wide range of influence and strong destructive. Therefore, we need to strengthen the monitoring and management analysis of lightning. Based on the analysis of historical lightning, valuable reference data and decision support are provided for important engineering activities, including water conservancy projects. But the traditional GIS is the application program which is established by the client / server mode. The system of this kind of mode is professional, powerful, specialized in operation, high in security and stability. With these advantages, this kind of geographic information system has been widely used in the past, but with the development of Internet technology and the increase of users' demand for distributed operation, How to combine Internet technology with geographic information technology to develop a system which can meet the needs of distributed operation and reduce the cost of using desktop GIS has become a new research direction. In this paper, the WebGIS system is applied to the management of lightning information, which can not only meet the functional requirements of the general lightning disaster prevention website, but also enable users to operate the lightning related spatial data conveniently. This paper first introduces the related knowledge of lightning and the technology needed to develop WebGIS (ArcGIS Server based) system, and then analyzes the relationship between the system and other systems according to the requirements of the subject. The functional modules and the design and development schemes of each module are designed according to the characteristics of the lightning data used in the system and the reasonable data model and data structure are adopted to determine the method of system development. Finally, the stability, security and management of lightning detection data (including spatial data and attribute data) are verified by the application examples of the system. The system can organize and manage the lightning information scattered in different areas and sites, publish the network, and provide data support for the majority of users.
