基于位置服务的移动GIS

随着移动终端的普遍应用，无线通信技术和地理信息系统的飞速发展，基于位置的服务LBS（Location Based Service）与移动GIS（Geographic Information system）相结合的应用模式已成为研究热点，并且开拓了一个具有无限潜能的市场. 本文首先论述了基于位置服务的移动GIS的基本概念，探讨了Android开发平台的系统架构与基于LBS的移动GIS体系结构，在此基础上设计了一个基于android平台的移动GIS系统，该系统在传统移动GIS的基础上进行了改进，克服了传统移动GIS缺乏社交互动性的缺点，不仅能够实现准确的实时定位与轨迹记录查询，还能够与好友互相分享实时位置以及进行多人轨迹的同时追踪，可以用于对老人儿童等弱势群体进行实时监护，也可以用于企业员工、车辆的管理调度等.

Mobile GIS Based on Location Services

With the rapid development of mobile terminal technology, wireless communication network technology and the universal application of geo-spatial information in all walks of life, the application mode that combines LBS with mobile GIS has become a hot research topic, and it opens up a market with unlimited potential. This paper discusses the basic concept of mobile GIS based on location services and the system architecture of Android development platform and the architecture of mobile GIS based on LBS. On the basis of this, a mobile GIS system based on Android platform is designed. The system has been improved on the basis of traditional mobile GIS, which overcomes the shortcomings of lack of social interaction in traditional mobile GIS, it not only can realize accurate real-time positioning and query trajectory, but also can share real-time location with friends and track the trajectory of many people at the same time. It can be used for real-time monitoring of the old elderly, children and other vulnerable groups, but also for employees, vehicle management scheduling.
