【摘要】：自从1946年诞生以来，计算机逐渐在我们的社会生活中扮演越来越重要的角色，我们也逐步迈入计算机时代，，同时也带来了一系列的计算模式的变革。地理信息系统（GIS）也随着计算机的发展进入了新的阶段，在决策支持方面得到了广泛的认可。20世纪60年代科学家们提出了互联网（Internet）的概念，到了20世纪90年代，由于计算机的发展和普及，随后Internet在全世界兴起，不仅带来了网络计算的概念，而且使我们进入了真正网络化的时代，GIS的发展也跟着进入了黄金时代，Web技术和GIS技术相结合，最令人激动的产物就是万维网地理信息系统（WebGIS），也带来了真正大众化的GIS。而随着信息技术的发展，移动通信技术与互联网技术、数据库等技术融合，在智能化电子通信设备的推动下，一种新的计算模式——移动计算应运而生，信息产业进入后PC时代‖，一种无处不在的计算，同时也带来了GIS的另一个产物移动地理信息系统（MobileGIS），一种无处不在的GIS。WebGIS和MobileGIS两大GIS的产物，随着时代的发展，二者必然会结合共同发展，共同为用户提供GIS服务，推动GIS的进一步发展。本文主要研究WebGIS与MobileGIS的协同技术，针对二者的特点探讨了如何将这两项技术更好的结合，并在现实生活中得到更好的应用。本文主要研究内容包括以下几个方面： 1、GIS系统框架服务的协同技术； 2、数据存储与数据调度的协同技术； 3、底层地图及坐标的统一。最后，论文以国家科技型中小企业技术创新基金项目——基于地理信息和位置服务的Web3D/SNS虚拟社区平台为例介绍了WebGIS与MobileGIS协同技术的具体应用情况。详细介绍了基于该技术并且结合虚拟现实技术和移动通信技术开发校园移动拼车系统的实现过程。
[Abstract]:Since its birth in 1946, computer has gradually played a more and more important role in our social life. Geographic Information system (GIS) has also entered a new stage with the development of computer. In the aspect of decision support, scientists put forward the concept of Internet (Internet) in 1960s. Because of the development and popularization of computer, the rise of Internet in the world has not only brought the concept of network computing, but also made us enter into the real era of networking. The development of GIS has also entered the golden age of combining Web technology and GIS technology. The most exciting product is the World wide Web Geographic Information system (WebGIS), which also brings the truly popular GIS. With the development of information technology, mobile communication technology, Internet technology, database and other technologies, driven by intelligent electronic communication equipment, a new computing mode-mobile computing came into being. With the development of the times, the information industry has entered the post-PC era, one kind of computing is everywhere, and at the same time, it brings another product of GIS, Mobile GIS, a product of GIS.WebGIS and MobileGIS. Both of them will combine the development of GIS and provide GIS service to users, and promote the further development of GIS. This paper mainly studies the cooperative technology of WebGIS and Mobile GIS, and discusses how to combine the two technologies better and get better application in real life according to the characteristics of the two technologies. The main contents of this paper are as follows: (1) collaborative technology of GIS frame service; (2) collaborative technology of data storage and data scheduling; (3) unification of bottom map and coordinate. Finally, the paper introduces the application of WebGIS and Mobile GIS based on WebGIS / SNS virtual community platform based on geographic information and location service. The realization process of campus mobile carpool system based on this technology and combined with virtual reality technology and mobile communication technology is introduced in detail.
