【摘要】：進(jìn)入二十一世紀(jì)后,以信息高速公路為主的信息革命發(fā)展時代,地理信息系統(tǒng)類學(xué)科的也得到了飛速發(fā)展,電子地圖作為一種以網(wǎng)絡(luò)服務(wù)商提供的新型的地圖產(chǎn)品,在此扮演的角色逐漸突出。由于數(shù)據(jù)表達(dá)與數(shù)據(jù)存儲相分離,致使現(xiàn)在的地圖展示方式有著明顯的動態(tài)特點(diǎn)以及表現(xiàn)力。隨著可視化技術(shù)與多媒體技術(shù)的應(yīng)用,電子地圖在互聯(lián)網(wǎng)中的表現(xiàn)空間信息以及用戶與系統(tǒng)的交互探究方面,顯示出了巨大的優(yōu)勢。 當(dāng)今互聯(lián)網(wǎng)以及基于移動運(yùn)營商為主的移動互聯(lián)網(wǎng)以其開放性和友好界面迅速成為網(wǎng)絡(luò)信息處理和發(fā)布的載體。隨著互聯(lián)網(wǎng)應(yīng)用的普及以及GIS技術(shù)的逐步推廣,應(yīng)用于web技術(shù)基礎(chǔ)上的地圖服務(wù)已經(jīng)成為主要的表現(xiàn)方式。 本文是在對WEBGIS服務(wù)發(fā)展應(yīng)用的基礎(chǔ)上,結(jié)合相關(guān)地圖服務(wù)的總體特征和發(fā)展現(xiàn)狀,對本地離線地圖以及本地地圖服務(wù)的延伸的理論和方法,進(jìn)行了探討。通過對系統(tǒng)的總體設(shè)計、內(nèi)容的結(jié)構(gòu)設(shè)計、系統(tǒng)的功能設(shè)計、界面設(shè)計,以GIS繪制軟件mapinfo為平臺,在C#與MAPINFO可視化開發(fā)環(huán)境下實(shí)現(xiàn)WEBGIS的系統(tǒng)集成。實(shí)現(xiàn)了基于校園gis的地圖服務(wù)的系統(tǒng)原型。本文的主要研究內(nèi)容如下： 1、對課題背景以及發(fā)展現(xiàn)狀進(jìn)行研究,總結(jié)了現(xiàn)今國內(nèi)外基于GIS位置服務(wù)的研究及發(fā)展現(xiàn)狀,對其發(fā)展趨勢和目前存在的問題進(jìn)行了分析和總結(jié)。并分析了目前主流WEBGIS商業(yè)平臺和開源平臺,根據(jù)C/S模式功能的多少以及處理任務(wù)的不同,分析基于WEBGIS支持下的網(wǎng)絡(luò)地圖的實(shí)現(xiàn)方式,即圖像方式,位圖要素方式以及矢量數(shù)據(jù)方式。 2、對GIS和基于web的地圖服務(wù)進(jìn)行研究,其中對相關(guān)的位置信息概念和用戶數(shù)據(jù)在WEBGIS中的數(shù)據(jù)綁定以及位置信息在地圖中的顯示方法和顯示層級的用途。介紹了基于OGC標(biāo)準(zhǔn)的WEBGIS服務(wù)規(guī)范以及空間數(shù)據(jù)組織管理方式。其中,OGC將地圖定義為地理數(shù)據(jù)的可視化表現(xiàn),地圖非數(shù)據(jù),而是利用標(biāo)記的png,gif以及jpeg等柵格圖形格式進(jìn)行表現(xiàn),或者用矢量圖形格式例如SVG或DXG等等。同時介紹了基于空間數(shù)據(jù)庫的地圖服務(wù)器模式,可以進(jìn)行更好的網(wǎng)絡(luò)地圖數(shù)據(jù)的存儲和組織。 3、確定了以WEBGIS和OGC標(biāo)準(zhǔn)為基礎(chǔ),提出基于mapinfo的MAPXTREME的網(wǎng)絡(luò)地圖體系結(jié)構(gòu)設(shè)計方案,采用插件模式的瘦客戶端／胖服務(wù)器形式的體系結(jié)構(gòu),地圖服務(wù)器通過接受web服務(wù)器請求,從空間數(shù)據(jù)庫中提取經(jīng)過檢索的滿足條件的空間數(shù)據(jù),行程特定目錄下給定文件名以及URL圖像,又web服務(wù)器發(fā)送到前端進(jìn)行顯示。與此同時,web服務(wù)器還可與數(shù)據(jù)庫進(jìn)行交互,完成非空間數(shù)據(jù)信息調(diào)用。利用胖服務(wù)器模式,所有數(shù)據(jù)均完成于服務(wù)器端,前端只需要提交請求并顯示相應(yīng)的響應(yīng)結(jié)果。在網(wǎng)絡(luò)地圖服務(wù)的數(shù)據(jù)組織中,用元數(shù)據(jù)表、地圖數(shù)據(jù)表、地圖索引數(shù)據(jù)表、用戶信息表分別存儲服務(wù)所需信息,采用sql數(shù)據(jù)庫管理地圖數(shù)據(jù),并利用mapxtreme空間數(shù)據(jù)插件mapx來提供數(shù)據(jù)存儲環(huán)境,且提供了GIS分析功能以及地圖交互功能。 4、依照基于MAPINFO的MAPXTREME平臺下WEBGIS服務(wù)設(shè)計方案,利用SQL管理空間數(shù)據(jù),設(shè)計并開發(fā)出基于校園GIS地圖服務(wù)系統(tǒng)。系統(tǒng)將不同的地理信息,地圖要素以及用戶交互功能相結(jié)合,形成一個基于區(qū)域地圖特色服務(wù)的平臺。同時完成校園GIS地圖服務(wù)系統(tǒng)的主要功能的實(shí)現(xiàn)。 5、對本文的研究進(jìn)行總結(jié),總結(jié)了成果及不足,指出了以后的發(fā)展方向。
[Abstract]:After entering the 21st century, the information revolution era with the information superhighway as the main part has witnessed the rapid development of geographic information system disciplines. As a new type of map products provided by network service providers, electronic maps have played an increasingly prominent role in this area. With the application of visualization technology and multimedia technology, electronic maps have shown great advantages in expressing spatial information on the Internet and exploring the interaction between users and systems.
Nowadays, the Internet and mobile Internet based on mobile operators have become the carrier of network information processing and publishing because of its openness and friendly interface. With the popularization of Internet applications and the gradual popularization of GIS technology, map services based on Web technology have become the main form of expression.
On the basis of the development and application of WEBGIS service, this paper discusses the theory and method of local off-line map and the extension of local map service, combining with the general characteristics and development status of related map service. Through the overall design of the system, the structure design of the content, the function design of the system, the interface design, the soft drawing with GIS is carried out. The system integration of WEBGIS based on C and MAPINFO is realized. The system prototype of map service based on campus GIS is realized. The main contents of this paper are as follows:
1. This paper studies the background and development status of the subject, summarizes the research and development status of GIS-based location service at home and abroad, analyzes and summarizes its development trend and existing problems, and analyzes the current mainstream WEBGIS business platform and open source platform, according to the number of C/S mode functions and processing tasks are not. Similarly, the implementation of web map based on WEBGIS is analyzed, including image mode, bitmap element mode and vector data mode.
2. Research on GIS and web-based map services, including the related concept of location information and the data binding of user data in WEBGIS, the display method of location information in the map and the use of display layer. Introduce the service specification of WEBGIS based on OGC standard and the way of spatial data organization and management. It is defined as the visual representation of geographic data. Maps are not data, but are represented by marker raster graphics formats such as png, GIF and jpeg, or vector graphics formats such as SVG or DXG.
3. Based on WEBGIS and OGC standards, a design scheme of MapXTREME network map architecture based on MapInfo is proposed. A thin client/fat server architecture with plug-in mode is adopted. The map server can extract the retrieved spatial data from the spatial database by accepting the request of the web server. At the same time, the web server can interact with the database to complete the non-spatial data information invocation. Using the fat server mode, all the data is completed on the server side, and the front end only needs to submit the request and display the corresponding response. Results. In the data organization of network map service, metadata table, map data table, map index data table and user information table are used to store the information needed by the service respectively. The map data is managed by SQL database, and the data storage environment is provided by MapXtreme spatial data plug-in mapx. The GIS analysis function and map interaction are also provided. Function.
4. According to the design scheme of WEBGIS service under MAPINFO-based MAPXTREME platform, a campus GIS map service system is designed and developed by using SQL to manage spatial data. The main functions of map service system are realized.
