【摘要】：进入二十一世纪后,以信息高速公路为主的信息革命发展时代,地理信息系统类学科的也得到了飞速发展,电子地图作为一种以网络服务商提供的新型的地图产品,在此扮演的角色逐渐突出。由于数据表达与数据存储相分离,致使现在的地图展示方式有着明显的动态特点以及表现力。随着可视化技术与多媒体技术的应用,电子地图在互联网中的表现空间信息以及用户与系统的交互探究方面,显示出了巨大的优势。 当今互联网以及基于移动运营商为主的移动互联网以其开放性和友好界面迅速成为网络信息处理和发布的载体。随着互联网应用的普及以及GIS技术的逐步推广,应用于web技术基础上的地图服务已经成为主要的表现方式。 本文是在对WEBGIS服务发展应用的基础上,结合相关地图服务的总体特征和发展现状,对本地离线地图以及本地地图服务的延伸的理论和方法,进行了探讨。通过对系统的总体设计、内容的结构设计、系统的功能设计、界面设计,以GIS绘制软件mapinfo为平台,在C#与MAPINFO可视化开发环境下实现WEBGIS的系统集成。实现了基于校园gis的地图服务的系统原型。本文的主要研究内容如下： 1、对课题背景以及发展现状进行研究,总结了现今国内外基于GIS位置服务的研究及发展现状,对其发展趋势和目前存在的问题进行了分析和总结。并分析了目前主流WEBGIS商业平台和开源平台,根据C/S模式功能的多少以及处理任务的不同,分析基于WEBGIS支持下的网络地图的实现方式,即图像方式,位图要素方式以及矢量数据方式。 2、对GIS和基于web的地图服务进行研究,其中对相关的位置信息概念和用户数据在WEBGIS中的数据绑定以及位置信息在地图中的显示方法和显示层级的用途。介绍了基于OGC标准的WEBGIS服务规范以及空间数据组织管理方式。其中,OGC将地图定义为地理数据的可视化表现,地图非数据,而是利用标记的png,gif以及jpeg等栅格图形格式进行表现,或者用矢量图形格式例如SVG或DXG等等。同时介绍了基于空间数据库的地图服务器模式,可以进行更好的网络地图数据的存储和组织。 3、确定了以WEBGIS和OGC标准为基础,提出基于mapinfo的MAPXTREME的网络地图体系结构设计方案,采用插件模式的瘦客户端／胖服务器形式的体系结构,地图服务器通过接受web服务器请求,从空间数据库中提取经过检索的满足条件的空间数据,行程特定目录下给定文件名以及URL图像,又web服务器发送到前端进行显示。与此同时,web服务器还可与数据库进行交互,完成非空间数据信息调用。利用胖服务器模式,所有数据均完成于服务器端,前端只需要提交请求并显示相应的响应结果。在网络地图服务的数据组织中,用元数据表、地图数据表、地图索引数据表、用户信息表分别存储服务所需信息,采用sql数据库管理地图数据,并利用mapxtreme空间数据插件mapx来提供数据存储环境,且提供了GIS分析功能以及地图交互功能。 4、依照基于MAPINFO的MAPXTREME平台下WEBGIS服务设计方案,利用SQL管理空间数据,设计并开发出基于校园GIS地图服务系统。系统将不同的地理信息,地图要素以及用户交互功能相结合,形成一个基于区域地图特色服务的平台。同时完成校园GIS地图服务系统的主要功能的实现。 5、对本文的研究进行总结,总结了成果及不足,指出了以后的发展方向。
[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.
