摘要
针对具有蓝牙功能的Java手机,提出了一种基于蓝牙GPS的移动GIS解决方案。该方案借助一个外置蓝牙GPS接收器获得移动终端的当前坐标,并将数据发送到服务器端,服务器依据该坐标进行重定中心运算生成栅格地图,并将地图数据返给客户端。该方案可实现普通手机的定位、查询和导航等地图服务功能。蓝牙GPS市场价格低廉,与为此更换GPS高端手机相比,节省了资源。系统基于J2ME技术实现,具有良好的扩展性。
A mobile GIS solution is provided which can provide LBS by adding an external Bluetooth GPS receiver, toward the mobile terminal which does not have in-line GPS-function. Through an external Bluetooth GPS receiver, the mobile terminal can get current position＇s coordinate, and create the gird map which marks the mobile terminal＇s current position. Terminal receive this map can easily find the current position of itself. The solution could achieve the target of map services and LBS for ordinary java phone. The price of Bluetooth GPS receive is low, adding Bluetooth GPS receiver can save resources. The client application in this solution is based on J2ME technology. This solution is suitable for mobile terminal which is Bluetooth-enabled and J2ME-enabled.
