移动地理位置信息系统的设计与实现
首发时间:2013-12-23
摘要:基于位置的服务为移动用户提供了许多生活上的便利,移动用户可以根据当前自己所处的位置来获取一些有用的信息。其中,Android是一个实现高附加值位置服务的良好平台。本文介绍了一个基于位置服务系统的设计与实现方法,这个系统包括Android客户端和LAMP服务器两个部分。Android客户端获取用户的地理位置信息并发送给LAMP服务器,LAMP服务器收到数据后在数据库中查找相应的商铺信息并返回给Android客户端,Android客户端对服务器返回的数据以列表的形式展示给用户。如果用户选择在谷歌地图中查看商铺的位置情况,Android客户端将对商铺和用户的位置在谷歌地图中进行展示。在谷歌地图中有两个附加功能,一个是更改地图显示模式,另一个是显示用户和商铺之间的路径,这两个功能可以通过点击Android客户端中谷歌地图界面中的两个功能按钮来实现。

Design & Implementation of the Mobile Geographical Location Information System
Abstract:Location Based Service (LBS) offers many advantages to the mobile users.Mobile users can retrieve their current location and use it to get more useful information near to their location. Android is a good platform for implementing LBS to provide these value-added services.This project is an android system based on LBS.It contains an android application and a LAMP server. The android application gets the user's current or last time location, then, send it to the LAMP server to get information of nearby shops. Once got the information, the android application displays them in the user interface.Then the user can view them and choose to display a shop in Google maps. There has two add-on functions in Google maps, one is to choose the map view's type, and the other one is to display a walking route between the user and the shop, these functions can be launched by tapping corresponding icons in the Google map's interface.
