【摘要】：嵌入式GIS系统以智能移动终端设备为平台,通过对多种技术的结合,能够随时随地为人们提供与位置信息相关的服务。如何将海量的空间信息和强大的应用服务功能扩展到移动终端上,以满足移动用户随时、随地对空间信息服务的需求,已经成为当前地理信息领域内研究的热点。随着GIS技术、移动定位技术、无线通信技术的不断发展,为移动空间信息服务的发展提供了新的契机。嵌入式GIS系统的最基本的功能就是导航功能,本文在分析嵌入式GIS系统关键技术的基础上,针对空间信息方便存储和快速显示的需求研究了电子地图数据的组织结构；针对空间数据尤其是导航道路数据变化快,现有数据更新周期长、现势性差的特点研究了空间数据的增量式更新技术。本文的研究工作主要包括以下几方面的内容： 1、通过大量阅读其他学者的研究文献,学习了嵌入式GIS的相关技术：移动终端操作系统技术、路径规划技术、公交查询技术、电子地图数据结构、电子地图在移动终端的调度与快速显示技术和导航电子地图的增量更新技术等。 2、在深入学习嵌入式GIS的相关技术的同时进行归纳总结,并设计了一种适用于嵌入式终端的电子地图数据存储结构,并研究了增量更新技术。 3、综合分析人们对嵌入式GIS的需求,设计一个具备基本功能的嵌入式GIS系统。 4、利用已有知识结合相关技术实现这个嵌入式GIS系统。 5、对嵌入式GIS的未来发展做出展望。
[Abstract]:The embedded GIS system takes the intelligent mobile terminal equipment as the platform, through the combination of various technologies, How to extend the massive spatial information and the powerful application service function to the mobile terminal, in order to meet the mobile user's demand for the spatial information service at any time, anywhere. With the development of GIS technology, mobile location technology and wireless communication technology, it provides a new opportunity for the development of mobile spatial information services. The most basic function of the embedded GIS system is the navigation function. Based on the analysis of the key technology of the embedded GIS system, this paper studies the organization structure of the electronic map data according to the requirement of convenient storage and fast display of the spatial information. According to the characteristics of spatial data, especially navigation road data, such as fast change, long updating period and poor present situation, the incremental updating technology of spatial data is studied. The research work of this paper mainly includes the following aspects:. 1. Through reading a lot of other scholars' research literature, we study the related technologies of embedded GIS: mobile terminal operating system technology, path planning technology, bus query technology, electronic map data structure, The scheduling and fast display technology of electronic map in mobile terminal and incremental updating technology of navigation electronic map, etc. 2. At the same time, the related technologies of embedded GIS are summarized and summarized, and an electronic map data storage structure suitable for embedded terminal is designed, and the incremental updating technology is studied. 3. The requirement of embedded GIS is analyzed synthetically, and an embedded GIS system with basic function is designed. 4. The embedded GIS system is realized by using the existing knowledge and related technology. 5. The future development of embedded GIS is prospected.
