【摘要】：隨著計(jì)算機(jī)技術(shù)的不斷發(fā)展和GIS應(yīng)用研究的不斷深入，把網(wǎng)絡(luò)技術(shù)與地理信息系統(tǒng)聯(lián)合起來，推進(jìn)了地理信息向著產(chǎn)業(yè)化和大眾化的目標(biāo)快速發(fā)展，所以產(chǎn)生了地理信息系統(tǒng)研究應(yīng)用中的一個(gè)發(fā)展方向，即網(wǎng)絡(luò)地理信息系統(tǒng)。把網(wǎng)絡(luò)地理信息系統(tǒng)（WebGIS）技術(shù)引進(jìn)到交通信息行業(yè)來解決日益嚴(yán)重的交通問題，進(jìn)而加快城市交通信息化的步伐，起到促進(jìn)經(jīng)濟(jì)發(fā)展目的。應(yīng)用WebGIS技術(shù)開發(fā)交通地理信息發(fā)布系統(tǒng)，對(duì)于緩解城市擁堵、滿足大眾出行具有重要的實(shí)際意義。 本論文基于.NET環(huán)境，以ArcGIS Server為GIS平臺(tái)開發(fā)了福建省交通地理信息發(fā)布系統(tǒng)。從WebGIS的概念、特點(diǎn)、理論基礎(chǔ)等入手研究探討系統(tǒng)開發(fā)實(shí)現(xiàn)過程中所應(yīng)用到的相關(guān)技術(shù)，最終實(shí)現(xiàn)論文中所敘述的交通地理信息發(fā)布系統(tǒng)，，本文主要從以下幾個(gè)方面進(jìn)行了系統(tǒng)的研究： 1、論述了交通地理信息系統(tǒng)在國內(nèi)外的發(fā)展現(xiàn)狀，以研究WebGIS的理論為基礎(chǔ)來分析比較WebGIS系統(tǒng)的幾種實(shí)現(xiàn)方案，選擇系統(tǒng)的開發(fā)平臺(tái)。 2、研究Ajax技術(shù)，應(yīng)用該技術(shù)實(shí)現(xiàn)客戶端與服務(wù)器端之間的數(shù)據(jù)異步傳輸。 3、針對(duì)ArcGIS Server理論進(jìn)行研究，較為詳細(xì)剖析地圖緩存技術(shù)。 4、設(shè)計(jì)和實(shí)現(xiàn)系統(tǒng)模塊，為用戶提供全省境內(nèi)的交通信息、一般地理要素信息和最短路徑查詢等信息。為交通地理信息系統(tǒng)實(shí)際應(yīng)用做了有益的探索，建立了簡單的交通地理信息發(fā)布系統(tǒng)，對(duì)其他交通信息系統(tǒng)的開發(fā)也提供了借鑒。
[Abstract]:With the continuous development of computer technology and the deepening of GIS application research, the combination of network technology and geographic information system promotes the rapid development of geographic information towards the goal of industrialization and popularization. Therefore, a developing direction in the research and application of geographic information system (GIS), that is, the network geographic information system (WebGIS), has emerged. The technology of Web GIS has been introduced into the traffic information industry to solve the increasingly serious traffic problems. To accelerate the pace of urban traffic information and promote economic development, the application of WebGIS technology in the development of transportation geographic information distribution system is of great practical significance to alleviate urban congestion and meet the needs of mass travel. Based on. Net environment and ArcGIS Server as the platform of GIS, this paper develops the traffic geographic information publishing system of Fujian Province. From the concept, characteristics and theoretical basis of WebGIS, this paper studies and discusses the relevant technologies applied in the process of system development and implementation. Finally, the transportation geographic information publishing system described in this paper is realized. This paper mainly studies the following aspects:. 1. This paper discusses the current situation of traffic geographic information system (TGIS) at home and abroad. Based on the research of WebGIS theory, this paper analyzes and compares several realization schemes of WebGIS system, and selects the development platform of the system. 2. Ajax technology is studied and used to realize asynchronous data transmission between client and server. 3. The theory of ArcGIS Server is studied, and the technology of map cache is analyzed in detail. 4. The system module is designed and implemented to provide users with the information of transportation information, general geographical element information and shortest path inquiry, etc. It makes a beneficial exploration for the practical application of traffic geographic information system (TGIS). A simple transportation geographic information publishing system is established, which can be used for reference in the development of other traffic information systems.
