【摘要】：近年来随着互联网技术的飞速发展,使用浏览器来访问互联网上的地理空间数据的需求大大增加。以局域网络为基础的传统地理信息系统无法满足互联网时代的需要。地理信息系统的用户数量以及应用领域有了显著的增长。如今,企业公司要面临复杂的事务,特别是在车辆跟踪领域。因此,有必要认识到,车队管理员采用诸如WEB GIS和远程信息处理等新的解决方案比几年前有着更好的可控性。这项工作的研究目的是调研影响GIS领域的网络技术,设计一个可扩展的WEB GIS车辆实时跟踪及其路(?)优化的架构模型。本工作采用的方法是将WEB GIS跟踪和道路优化设计为子模块,每个模块在不同的平台上独立研究和实现。第一个模块是网络映射;该服务允许通过集成本地空间数据库服务器来管理空间数据;该模块通过WMS,WFS和WPS服务提供对空间数据的可互操作访问,符合WEB GIS和OGC标准的要求。第二个模块是车辆跟踪及其管理模块,该模块在开源软件OpenGTS上实现;该模块实现GPS事件的跟踪。该软件的编程语言为java;设计原则是打破其架构,并使用新的Web服务架构将其所有功能进行包装作为服务发布,并开发一个用于从完全不同的python平台为车辆管理开发OpenGTS提供的功能的场景。目标是通过空间和非空间数据传输,以及通过管理两个平台之间的互操作来调用过程。以透明的方式将这种集成到统一的架构中。XML-RPC允许两个或多个使用不同语言或平台下开发实现的Web GIS组件共享数据和操作。XML-RPC用于收集我们的Web GIS组件,并使用XML数据解决互操作性和服务调用问题。该WEBGIS架构还着重推出定制服务以改进车辆路(?),实现最短路径优化,该方法使用基于图论理论领域的Dijkstra算法模型。Dijkstra算法已被用来从想要执行路(?)选择优化的两个位置实现基于边长的最短路径选择,使用XML通过http协议将POST-WPS请求发送到地理服务器;服务器接收查询请求,并在XML响应中返回feature列表;从该响应中可以提取数据以此构建Dijkstra算法路由表。数据结果是连续节点的列表,将用于传递向量表示,并在地图容器中作为路径进行显示。总之,该WEB GIS系统研究成果并不局限于车辆跟踪功能或严格依赖于某平台,通过XML-RPC接口可以将其集成到任何的组织基础架构中,并通过XML文件以透明的方式实现数据和操作的互操作。
[Abstract]:In recent years, with the rapid development of Internet technology, the need to use browsers to access geospatial data on the Internet has increased greatly. The traditional geographic information system based on local area network can not meet the needs of the Internet era. There has been a significant increase in the number of users and applications of GIS. Today, companies face complex business, especially in the area of vehicle tracking. Therefore, it is necessary to realize that new solutions such as Web GIS and remote information processing are more controllable than they were a few years ago. The purpose of this work is to investigate the network technology that affects GIS, and to design an extensible Web GIS vehicle real-time tracking and road tracking. Optimized architecture model. The method used in this work is to design Web GIS tracking and road optimization as sub-modules, and each module is independently studied and implemented on different platforms. The first module is network mapping, which allows spatial data to be managed by integrating local spatial database servers. The module provides interoperable access to spatial data through WMSWFS and WPS services, which meet the requirements of Web GIS and OGC standards. The second module is the vehicle tracking and its management module, which is implemented on the open source software OpenGTS, and realizes the GPS event tracking. The software's programming language is java; the design principle is to break its architecture and use the new Web services architecture to wrap all of its functionality as a service distribution. Develop a scenario for developing OpenGTS functionality for vehicle management from a completely different python platform. The goal is to transfer both spatial and non-spatial data, and to invoke procedures by managing interoperability between the two platforms. Integrating this in a transparent manner into a unified architecture .XML-RPC allows two or more Web GIS components developed and implemented in different languages or platforms to share data and manipulate .XML-RPC to collect our Web GIS components. And use XML data to solve interoperability and service invocation problems. The WEBGIS architecture also emphasizes the introduction of customized services to improve vehicle routing and achieve shortest path optimization. The method uses Dijkstra algorithm model based on graph theory. Dijkstra algorithm has been used from the desired execution route. Selecting the optimized two locations to realize the shortest path selection based on the side length, sending the POST-WPS request to the geographic server through http protocol, the server receives the query request, and returns the feature list in the XML response. The data can be extracted from the response to construct the routing table of Dijkstra algorithm. The data result is a list of consecutive nodes, which will be used to represent the transfer vector and be displayed as a path in the map container. In a word, the research results of this Web GIS system are not limited to the vehicle tracking function or are strictly dependent on a certain platform, but can be integrated into any organization infrastructure through the XML-RPC interface. And through the XML file in a transparent way to achieve data and operation interoperability.
