【摘要】：移动GIS是在嵌入式系统的基础上集成先进的移动定位技术、移动计算技术、移动通信技术,以拓展地理信息系统的应用范围,提高地理信息系统数据采集和数据管理能力为目的的计算机系统。随着嵌入式备计算能力的提高以及移动定位技术与移动通信技术的快速发展,利用移动GIS进行和位置相关的数据采集成为移动GIS的一个重要应用方向。论文从移动GIS在国内外研究和发展的状况出发,阐述了在移动获取地理信息方面存在的问题和开发移动GIS在该方面应用的意义,然后分析了移动GIS发展的相关技术,针对传统的移动数据采集方式中存在的采集数据精度和效率低以及现有的移动数据采集系统偏重于空间位置测量等问题,论文以土地利用现状调查为背景,将移动GIS技术、GPS定位技术用于土地利用调查实时显示的数据采集。设计并开发了基于移动GIS技术的土地利用调查实时显示系统,该系统除了具有传统的空间信息显示、查询、分析等功能外,还可以实现实时的定位导航功能。更重要的是,它能保存采集到的数据,并把它转换成包含空间信息的电子地图,实现数据的重复利用,同时通过无线业务(GPRS)无线上网技术实现数据的上传下载和野外实时更新地图数据。
[Abstract]:Mobile GIS integrates advanced mobile positioning technology, mobile computing technology and mobile communication technology on the basis of embedded system to expand the application scope of GIS. A computer system designed to improve the ability of data acquisition and data management in geographic information systems (GIS). With the improvement of embedded standby computing ability and the rapid development of mobile positioning technology and mobile communication technology, it is an important application direction of mobile GIS to use mobile GIS to collect location-related data. Starting from the research and development of mobile GIS at home and abroad, this paper expounds the existing problems in mobile access to geographic information and the significance of developing mobile GIS in this field, and then analyzes the related technologies of mobile GIS development. Aiming at the problems of low precision and efficiency in the traditional mobile data acquisition and the emphasis on the spatial position measurement in the existing mobile data acquisition system, the paper takes the survey of land use status as the background. The mobile GIS technology is applied to the real time display data acquisition of land use survey. A land use survey real-time display system based on mobile GIS technology is designed and developed. Besides the traditional functions of spatial information display, query and analysis, the system can also realize real-time positioning and navigation functions. More importantly, it can save the collected data and convert it into an electronic map containing spatial information, so that the data can be reused. At the same time, it can upload and download data and update map data in real time through wireless service GPRS.
