实现移动终端上的电子地图查询和导航功能对城市旅游事业的发展具有重要作用。在申请GoogleMapAPIKey的基础上,基于Android开发平台,通过Java语言调用GoogleMap,可以开发和实现基于Android系统的电子地图应用系统。文中介绍了Android系统平台的搭建、GoogleMapAPI的功能和GoogleMapAPIKey的申请过程,探讨了GoogleMapAPI在电子地图服务中的应用,并以西安旅游智能地图手机软件为例,设计并实现了一个在线移动旅游服务平台,这为移动用户快速通过智能手机获取和导航景点地理信息提供支持。
Implementing the functions of query and navigation about electronic map on mobile terminals is important for the tourism de- velopment of a city. On the basis of applying the Google Map API Key,based on the Android development platform, electronic map ap- plication systems can be implemented on Android systems by invoking the Google Map with Java. In this paper, Android development platform slructure, functionality of the Google Map API and Google Map API Key application process are described in detail. Further- more, to explore the electronic map service, an intelligent electronic map mobile platform for Xi' an tourism is designed and implemented, through which mobile users can efficiently require and navigate the position of any tourism attraction in their smart phones.
